Gameplay
''Q*bert'' is an action game with Puzzle video game, puzzle elements played from an Isometric video game graphics, axonometric third-person perspective to convey a three-dimensional look. The game is played using a single, diagonally mounted four-way joystick. The player controls Q*bert, who starts each game at the top of a pyramid made of 28 cubes, and moves by hopping diagonally from cube to cube. Landing on a cube causes it to change color, and changing every cube to the target color allows the player to progress to the next Level (video games), stage. At the beginning, jumping on every cube once is enough to advance. In later stages, each cube must be hit twice to reach the target color. Other times, cubes change color every time Q*bert lands on them, instead of remaining on the target color once they reach it. Both elements are then combined in subsequent stages. Jumping off the pyramid results in the character's death. The player is impeded by several enemies, introduced gradually to the game: * Coily – Coily first appears as a purple egg that bounces to the bottom of the pyramid and then transforms into a snake that chases after Q*bert. He is often considered the main antagonist and Q*bert's arch-nemesis. * Ugg and Wrongway – Two purple creatures that hop along the sides of the cubes in an Relativity (M. C. Escher), Escheresque manner. Starting at either the bottom left or bottom right corner, they keep moving toward the top right or top left side of the pyramid respectively and fall off the pyramid when they reach the end. * Slick and Sam – Two green creatures that descend down the pyramid and revert cubes whose color has already been changed. A collision with purple enemies is fatal to the character, whereas the green enemies are removed from the board upon contact. Colored balls occasionally appear at the second row of cubes and bounce downward; contact with a red ball is lethal to Q*bert, while contact with a green one immobilizes the on-screen enemies for a limited time. Multicolored floating discs on either side of the pyramid serve as an escape from danger, particularly Coily. When Q*bert jumps on a disc, it transports him to the top of the pyramid. If Coily is in close pursuit of the character, he will jump after Q*bert and fall to his death, awarding bonus points. This causes all enemies and balls on the screen to disappear, though they start to return after a few seconds. Points are awarded for each color change (15 or 25), defeating Coily with a flying disc (500), remaining discs at the end of a stage (at higher stages, 50 or 100) and catching green balls (100) or Slick and Sam (300 each). Bonus points are also awarded for completing a screen, starting at 1,000 for the first screen of Level 1 and increasing by 250 for each subsequent completion, up to 5,000 after Level 4. 1-up, Extra lives are granted for reaching certain scores, which are set by the machine operator.Development
Concept
Programmer Warren Davis wrote that he was inspired by a pattern of hexagons implemented by fellow Gottlieb developer and ''Mad Planets'' designer Kan Yabumoto. In a different telling, the initial concept began when artist Jeff Lee drew a pyramid of cubes inspired by M. C. Escher. Lee believed a game could be derived from the artwork, and created an orange, armless main character. The character jumped along the cubes and shot projectiles, called "mucus bombs", from a tubular nose at enemies. Enemies included a blue creature, later changed purple and named Wrong Way, and an orange creature, later changed green and named Sam. Lee had drawn similar characters since childhood, inspired by characters from comics, cartoons, ''Mad (magazine), Mad'' magazine and by artist Ed "Big Daddy" Roth. Q*bert's design later included a speech balloon with wikt:grawlix, a string of nonsensical characters, "",The original artwork displays the first and fifth character as spirals. The at sign ("@") is used in its place in the text of the references. which Lee originally presented as a joke.Implementation
Warren Davis, who was hired to work on the game ''Protector'', noticed Lee's ideas and asked if he could use them to practice programming randomness and gravity as game mechanics. Thus, he added balls that bounce from the pyramid's top to bottom. Because Davis was still learning how to program game mechanics, he wanted to keep the design simple. He also believed games with complex control schemes were frustrating and wanted something that could be played with one hand. To accomplish this, Davis removed the shooting and changed the objective of saving the protagonist from danger. As Davis worked on the game one night, Gottlieb's vice president of engineering, Ron Waxman, noticed him and suggested to change the color of the cubes after the game's character has landed on them. Davis implemented a unique control scheme; a four-way joystick was rotated 45° to match the directions of Q*bert's jumping. Staff members at Gottlieb urged for a more conventional orientation, but Davis stuck to his decision. Davis remembered to have started programming in April 1982, but the project was only put on the schedule as an actual product several months later.Davis stated that this happened "by June or July", whereas Howie Rubin, vice president of Gottlieb, claimed in an early 1983 interview with Video Games that the game was not yet on a list of games voted for in a brainstorming session in August.Audio
A MOS Technology 6502 chip that operates at 894 kHz generates the sound effects, and a Speech synthesis, speech synthesizer by Votrax generates Q*bert's incoherent expressions. The audio system uses 128 Byte, B of random-access memory, RAM and 4 Kilobyte, KB of EPROM to store the sound data and code to implement it. Like other Gottlieb games, the sound system was thoroughly tested to ensure it would handle daily usage. In retrospect, audio engineer David Thiel commented that such testing minimized time available for creative designing. Thiel was tasked with using the synthesizer to produce English phrases for the game. However, he was unable to create coherent phrases and eventually chose to string together random phonemes instead. Thiel also believed the incoherent speech was a good fit for the "" in Q*bert's speech balloon. Following a suggestion from technician Rick Tighe, a pinball machine component known as a ‘knocker’ was included to make a loud sound when a character falls off the pyramid. This knocker consists of a solenoid with a plunger that strikes the mounting bracket (which in turn is firmly fastened to the cabinet). Foam padding was added to the area of contact on the bracket; the developers decided the softer sound better matched a fall rather than a loud knocking sound. The cost of installing foam, however, was too expensive and the padding was omitted.Title
The Gottlieb staff had difficulty naming the game. Aside from the project name "''Cubes''", it was untitled for most of the development process. The staff agreed the game should be named after the main character, but disagreed on the name. Lee's title for the initial concept—''Snots And Boogers''—was rejected, as was a list of suggestions compiled from company employees. According to Davis, vice president of marketing Howie Rubin championed ' as the title. Although staff members argued it was silly and would be impossible to pronounce, a few early test models were produced with ' as the title on the units' artwork. During a meeting, "Hubert" was suggested, and a staff member thought of combining "Cubes" and "Hubert" into "Cubert". Art director Richard Tracy changed the name to "Q-bert", and the hyphen was later changed to an asterisk. In retrospect, Davis expressed regret for the asterisk, because it prevented the name from becoming a common crossword term and it is a wildcard character for Search engine (computing), search engines.Testing
As development neared the production stage, ''Q*bert'' underwent location tests in local Amusement arcade, arcades under its preliminary title ', before being widely distributed. According to Jeff Lee, his oldest written record attesting to the game being playable as ' in a public location, a Brunswick bowling alley, dates back to September 11, 1982. Gottlieb also conducted focus groups, in which the designers observed players through a one-way mirror. The control scheme received a mixed reaction during playtesting; some players adapted quickly while others found it frustrating. Initially, Davis was worried players would not adjust to the different controls; some players would unintentionally jump off the pyramid several times, reaching a game over in about ten seconds. Players, however, became accustomed to the controls after playing several rounds of the game. The different responses to the controls prompted Davis to reduce the game's level of difficulty, a decision that he would later regret.Release
''Q*bert'' is Gottlieb's fourth video game. A copyright claim registered with the United States Copyright Office by Gottlieb on February 10, 1983 cites the date of publication of ''Q*bert'' as October 18, 1982. ''Video Games'' reported that the game was sold directly to arcade operators at its public showing at the AMOA show held November 18–20, 1982. Gottlieb offered the machines for $2600 per unit. ''Cash Box'' magazine listed the mass-market US release date as December 1982. The game was distributed in Japan by Konami and Sega in March 1983. It was also released in Europe in March 1983.Reception
''Q*bert'' is Gottlieb's only video game that earned considerable critical and commercial success, selling around 25,000 arcade cabinets. In the United States, it was among the thirteen highest-grossing 1983 in video games, arcade games of 1983. Arcade cabinet#Mini cabinets, Cabaret and Arcade cabinet#Cocktail or table cabinets, cocktail versions of the game were later produced. The machines have since become Collectable, collector's items; the rarest of them are the cocktail versions. When the game was first introduced to a wider industry audience at the November 1982 AMOA show, it was immediately received favorably by the press. ''Video Games'' magazine placed ''Q*bert'' first in its list of Top Ten Hits, describing it as "the most unusual and exciting game of the show" and stating that "no operator dared to walk away without buying at least one". ''The Coin Slot'' reported "Gottlieb's game, Q*BERT, was one of the stars of the show", and predicted that "The game should do very well". Contemporaneous reviews were equally enthusiastic, and focused on the uniqueness of the gameplay and audiovisual presentation. Roger C. Sharpe of ''Electronic Games'' considered it "a potential Arcade Award winner for coin-op game of the year", praising innovative gameplay and outstanding graphics. William Brohaugh of ''Creative Computing Video & Arcade Games'' described the game as an "all-round winner" that had many strong points. He praised the variety of sound effects and the graphics, calling the colors vibrant. Brohaugh lauded ''Q*bert''s inventiveness and appeal, stating that the objective was interesting and unique. Michael Blanchet of ''Electronic Fun'' suggested the game might push ''Pac-Man'' out of the spotlight in 1983. Neil Tesser of ''Video Games'' also likened ''Q*bert'' to Japanese games like ''Pac-Man'' and ''Donkey Kong'', due to the focus on characters, animation and story lines, as well as the "absence of violence". ''Computer and Video Games'' magazine praised the game's graphics and colors. ''Electronic Games'' awarded ''Q*bert'' "Most Innovative Coin-op Game" of the year. ''Video Games Player'' called it the "Funniest Game of the Year" among arcade games in 1983. ''Q*bert'' continues to be recognized as a significant part of video game history. Author Steven Kent and GameSpy's William Cassidy considered ''Q*bert'' one of the more memorable games of its time. Author David Ellis echoed similar statements, calling it a "classic favorite". 1UP.com's Jeremy Parish and Kim Wild of ''Retro Gamer'' magazine described the game as difficult yet addictive. Author John Sellers also called ''Q*bert'' addictive, and praised the sound effects and 3D computer graphics, three-dimensional appearance of the graphics. Cassidy called the game unique and challenging; he attributed the challenge in part to the control scheme. IGN's Jeremy Dunham believed the controls were poorly designed, describing them as "unresponsive" and "a struggle". He nonetheless considered the game addictive. ''Edge (magazine), Edge'' magazine attributed the success of the game to the title character. They stated that players could easily relate to Q*bert, particularly because he swore. ''Computer and Video Games'', however, considered the swearing a negative but the character appealing. Cassidy believed the game's appeal lay in the main character. He described Q*bert as cute and having a personality that made him stand out in comparison to other popular video game characters. The authors of ''High Score!'' referred to Q*bert as "ultra-endearing alien hopmeister", and the cutest game character of 1982.Ports
At the 1982 AMOA Show, Parker Brothers secured the license to publish home conversions of the ''Q*bert'' arcade game. Parker Brothers first published a port to the Atari 2600, and by the end of 1983, the company also advertised versions for Atari 5200, Intellivision, ColecoVision, the Atari 8-bit computer family, VIC-20, TI-99/4A, and Commodore 64. The release of the Commodore 64 version was noted to lag behind the others but appeared in 1984. Parker Brothers also translated the game into a standalone tabletop electronic game. It uses a Vacuum fluorescent display, VFD screen, and has since become a rare collector's item. ''Q*bert'' was also published by Parker Brothers for the Magnavox Odyssey 2, Philips Videopac in Europe, by Tsukuda Original for the SG-1000, Othello Multivision in Japan, and by Ultra Games for the Nintendo Entertainment System, NES in North America. The initial home port for the Atari 2600, the most widespread system at the time, was met with mixed reactions. ''Video Games'' warned that buyers of the Atari 2600 version "may find themselves just a little disappointed." They criticized the lack of music, the removal of the characters Ugg and Wrongway, and the system's troubles handling the character sprites at a steady performance. Later, Mark Brownstein of the same magazine was more in favor of the game, but still cited the presence of fewer cubes in the game's pyramidal layout and "pretty poor control" as negatives. Will Richardson of ''Electronic Games'' noted a lack in audiovisual qualities and counter-intuitive controls, but commended the gameplay, stating that the game "comes much closer to its source of inspiration than a surface evaluation indicates." Randi Hacker of ''Electronic Fun with Computers & Games'' called it a "sterling adaption" ''Computer and Video Games'' scored the Atari 2600, Atari VCS version 70% in 1989. In 2008, IGN's Levi Buchanan rated it the fourth-worst arcade port for the Atari 2600, mostly because of a lack of jumping animations for enemies, which instead appear instantly on the adjacent cube, making it impossible to know in which direction they are traveling before they land. ''Entertainment Weekly'' called ''Q*Bert'' one of the top ten games for the Atari 2600 in 2013, saying the port "lost the cool isometric perspective but none of the addictive gameplay." Other home versions were well-received, with some exceptions. Of the ColecoVision version, ''Electronic Fun with Computers & Games'' noted that "''Q*bert'' aficionados will not be disappointed." Brownstein called it one of the best of the authorized versions. Warren Davis also considered the ColecoVision version the most accurate port of the arcade. ''Computer and Video Games'' gave the ColecoVision version a 72% score. Brownstein judged the Atari 5200 version inferior to that for the ColecoVision because of the imprecision of the Atari 5200 controller, but noted that "it does tend to grow on you." ''Video Games'' identified the Intellivision version as the worst of the available ports, criticizing the system's controller as inadequate for the game. ''Antic (magazine), Antic'' magazine's David Duberman called the Atari 8-bit version "one of the finest translations of an arcade game for the home computer format", and Arthur Leyenberger of ''Creative Computing'' listed it as a runner-up for Best Arcade Adaptation to the system, praising its faithful graphics, sound, movement and playability. ''Softline (magazine), Softline'' was more critical, criticizing the Atari version's controls and lack of swearing. The magazine concluded that "the home computer game doesn't have the sense of style of the one in the arcades ... the execution just isn't there." In 1984, the magazine's readers named the game the fifth-worst Atari program of 1983. ''Computer Games (magazine), Computer Games'' called the C64 version an "absolutely terrific translation" that "almost totally duplicates the arcade game," aside from its lack of synthesized speech. The standalone tabletop was awarded Stand-Alone Game of the Year in ''Electronic Games''. ''Electronic Gaming Monthly'' reviewed the NES version in 1989, with four critics scoring it 7, 3, 4 and 4 out of 10. In 2003, a version for Java-based mobile phones was announced by Sony Pictures Mobile. Reviewers generally acknowledged it as a faithful port of the arcade original, but criticized the controls. ''Modojo''Legacy
According to Jeremy Parish, ''Q*bert'' is "one of the higher-profile titles of the classic era". In describing ''Q*bert''s legacy, Jeff Gerstmann of GameSpot referred to the game as a "rare arcade success". In 2008, ''Guinness World Records'' ranked it behind 16 other arcade games in terms of their technical, creative and cultural impact. Though successful, the creators of the game did not receive royalties, as Gottlieb had no such program in place at the time. Davis and Lee nonetheless expressed pride about the game continuing to be remembered fondly.Market impact
''Q*bert'' became one of the most merchandised arcade games behind ''Pac-Man'', although according to John Sellers it was not nearly as successful as that franchise or ''Donkey Kong (video game), Donkey Kong''. The character's likeness appears on various items including coloring books, sleeping bags, frisbees, board games, wind-up toys, and stuffed animals. In a flyer distributed in 1983, Gottlieb claimed over 125 licensed products. However, the video game crash of 1983 depressed the market, and the game's popularity began to decline by 1984. In the years following its release, ''Q*bert'' inspired many other games with similar concepts. The magazines ''Video Games'' and ''Computer Games'' both commented on the trend with features about ''Q*bert''-like games in 1984. They listed ''Mr. Cool (video game), Mr. Cool'' by Sierra On-Line, ''Frostbite (video game), Frostbite'' by Activision, ''Q-Bopper'' by Accelerated Software, ''Juice'' by Tronix, ''Quick Step'' by Imagic, ''Flip & Flop'' and ''Boing'' by First Star Software, ''Pharaoh's Pyramid'' by Master Control Software, ''Pogo Joe'' by Screenplay, ''Rabbit Transit'' by Starpath, as games which had been inspired by ''Q*bert''. Further titles that have been identified as ''Q*bert''-like games include ''Cubit'' by Micromax, ''J-bird'' by Orion Software, and in the UK ''Bouncer'' by Acornsoft, ''Hubert'' by Blaby Computer Games, ''Pogo'' by Ocean Software, Ocean, ''Spellbound'' by Beyond and ''Vector Hopper'' by Kristof Tuts.In other media
In 1983, ''Q*bert'' was adapted into an animated cartoon as part of ''Saturday Supercade'' on CBS, which features segments based on video game characters from the golden age of video arcade games. ''Saturday Supercade'' was produced by Ruby-Spears Productions, the ''Q*bert'' segments between 1983 and 1984. The show is set in a United States in the 1950s, United States, 1950s era town called "Q-Burg", and stars Q*bert as a high school student, altered to include arms, hands, jacket, and sneakers. He shoots black projectiles from his nose, what he calls "Slippy Dew", to make his enemies slip. Characters frequently say puns that add the letter "Q" to words. ''Q*bert'' is seen being played in the 1984 film ''Moscow on the Hudson'' starring Robin Williams. The 1993 IBM PC Role-playing video game, role-playing game ''Ultima Underworld II: Labyrinth of Worlds'' has a segment where the player has to solve a pyramid puzzle as a homage to ''Q*bert''. In the 2009 action-adventure game ''Ghostbusters: The Video Game'', a ''Q*bert'' arcade cabinet can be seen in the Ghostbusters headquarters. ''Q*bert'' characters appear in Disney's ''Wreck-It Ralph (franchise), Wreck-It Ralph'' franchise. Q*bert appears in ''Pixels (2015 film), Pixels''. In 2014, Q*bert makes a cameo appearance in the RadioShack Super Bowl XLVIII commercial "The '80s Called". The game has been referenced in several animated television series: ''Family Guy'', ''Futurama'', ''The Simpsons'', ''Robot Chicken'', ''Mad (TV series), Mad'', and ''South Park''.High scores
On November 28, 1983, Rob Gerhardt reached a record score of 33,273,520 points in a ''Q*bert'' marathon. He held it for almost 30 years, until George Leutz from Brooklyn, New York played one game of ''Q*bert'' for eighty-four hours and forty-eight minutes on February 14–18, 2013 at Richie Knucklez' Arcade in Flemington, New Jersey. He scored 37,163,080 points. Doris Self, credited by ''Guinness World Records'' as the "oldest competitive female gamer", set the tournament record score of 1,112,300 for ''Q*bert'' in 1984 at the age of 58. Her record was surpassed by Drew Goins on June 27, 1987 with a score of 2,222,220. Self continually attempted to regain the record until her death in 2006. On November 18, 2012, George Leutz broke the ''Q*Bert'' tournament world record live at the Kong Off 2 event at The 1up Arcade and Bar in Denver, Colorado. Leutz scored 3,930,990 points in just under eight hours, earning 1.5 million points on his first life, beating Self's score using a single life. Leutz's score was verified by Twin Galaxies. The video ends at a score of 3.7 Million points, 1,500,000 points over the previous record.Updates, remakes, and sequels
''Faster Harder More Challenging Q*bert''
Believing that the original game was too easy, Davis initiated development of ''Faster Harder More Challenging Q*bert'' in 1983, which increases the difficulty, introduces Q*bertha, and adds a bonus round. The project was canceled. Davis released the ROM image onto the web in December 1996.''Q*bert's Quest''
Gottlieb released the pinball game ''Q*berts Quest'' in 1983. It has two pairs of Flipper (pinball), flippers in an "X" formation and uses audio from the arcade game. Gottlieb produced fewer than 900 units, but in Japan ''Game Machine'' listed ''Q*bert's Quest'' in their June 1, 1983 issue as being the second most-successful flipper unit of the year.''Q*bert's Qubes''
Several video game sequels were released over the years, but did not reach the same level of success as the original. The first, titled ''Q*bert's Qubes'', shows a copyright for 1983 on its title screen, whereas the instruction manual cites a 1984 copyright. It was manufactured by Mylstar ElectronicsThe Coca-Cola Company acquired Columbia Pictures, Gottlieb's owner, in 1982, and renamed the company to Mylstar Electronics, in 1983. and uses the same hardware as the original. The game features Q*bert, but introduces new enemies: Meltniks, Shoobops, and Rat-A-Tat-Tat. The player navigates the protagonist around a plane of cubes while avoiding enemies. Jumping on a cube causes it to rotate, changing the color of the visible sides of the cube. The goal is to match a line of cubes to a target sample; later levels require multiple rows to match. Though part of a popular franchise, the game's release was hardly noticed. Parker Brothers showcased home versions of ''Q*bert's Qubes'' at the Winter Consumer Electronics Show in January 1985. ''Q*bert's Qubes'' was ported to the ColecoVision and Atari 2600. Version for Atari 8-bit computers and the Commodore 64 were referred to in the instructions of the released conversions. The Atari 8-bit version has not yet been found, but Games That Weren't tracked down a preview of the C64 version in 2017.MSX ''Q*bert'' (1986)
Konami, who had distributed the original ''Q*bert'' to Japanese arcades in 1983, produced a different game, that kept the title ''Q*bert'', released in Japan and Europe for MSX computers in 1986. The main character is a little dragon, and the mechanics are based on ''Q*bert's Qubes''. Each of the 50 stages has a different pattern of cubes. The competitive 2-player mode assigns each side a different pattern, and the players score points either by completing their pattern first or by pushing the other off the board.''Q*bert'' for Game Boy
Developed by Realtime Associates and published by Jaleco in 1992, this version has 64 boards in different shapes.''Q*bert 3''
''Q*bert 3'' for the Super Nintendo Entertainment System, Super NES was developed by Realtime Associates and published by NTVIC in 1992. Jeff Lee worked on the graphics. It has gameplay similar to the original, but like the Game Boy game, has larger levels of varying shapes. In addition to enemies from the first game, it introduces Frogg, Top Hat, and Derby.''Q*bert'' (1999)
Q*bert is a remake of the 1982 arcade game of the same name with 3D graphics. It was developed by Artech Studios and released by Hasbro Interactive on the PlayStation and Microsoft Windows in 1999 and on the Dreamcast in 2000.''Q*bert 2004''
In 2004, Sony Pictures released a sequel for Adobe Flash titled ''Q*bert 2004'', containing a faithful rendition of the original arcade game, along with 50 levels that use new board layouts and six new visual themes. ''Q*Bert Deluxe'' for iOS devices was initially released as a rendition of the arcade game, but later received updates with the themes and stages from ''Q*Bert 2004''.''Q*bert 2005''
In 2005, Sony Pictures released ''Q*bert 2005'' as a download for Windows and as a Flash browser applet, featuring 50 different levels.''Q*bert Rebooted''
On July 2, 2014, Gonzo Games and Sideline amusement announced ''Q*bert Rebooted'' to be released on Steam, iOS and Android. Versions for PlayStation 3, PlayStation 4 and PlayStation Vita were released on February 17, 2015 in North America and February 18, 2015 in Europe. It was released on February 12, 2016 for the Xbox One. According to Mark Caplan, Vice President, Consumer Products, Worldwide Marketing & Distribution at Sony Pictures Entertainment, the release was motivated by "renewed interest in ''Q*bert'', in part due to the cameo in the recent ''Wreck-It Ralph'' animated feature film". ''Q*bert Rebooted'' contains a port of the classic arcade game alongside a new playing mode that uses hexagonal shapes, increasing the number of possible movement directions to six. Additionally, the 'Rebooted' mode features new enemy types, including a boxing glove that punches Q*bert off the levels and a treasure chest that tries to avoid him. The game has 5 different stage designs spread across 40 levels, which contain three rounds and a bonus round and have to be completed with 5 lives. Gems are collected to unlock different skins for the Q*bert character, and completing levels multiple times while reaching specific time and score goals is awarded with stars that enable access to more levels.''Q*bert (2019)''
On October 11, 2019, an updated version of ''Q*bert'' developed by Lucky-Kat games in association with Sony Pictures was published via the iOS app store.Notes
