Java was at one time the most common platform for mobile games, however its performance limits led to the adoption of various native binary formats for more sophisticated games. Due to its ease of porting between mobile operating systems and extensive developer community, Unity is one of the most widely used engines used by modern mobile games. Apple provide a number of proprietary technologies (such as Metal) intended to allow developers to make more effective use of their hardware in iOS-native games.

and support for in-app purchases by October 2009, the methods through which mobile games earn revenue have diverged significantly away from traditional game models on consoles or computers. Since 2009, a number of models have developed, and a mobile game developer/publisher may use one or a combination of these models to make revenue. ;Premium :The premium model is akin to the traditional model where the user pays for the full game upfront. Additional downloadable content may be available which can be purchased separately. Initial games released to the App Store before in-app purchases were available used this approach, and still common for many types of games. ;Freemium :The

or "free to try" model offers a small portion of the game for free, comparable to a game demo. After completing this, the player is given the option to make a one-time in-app purchase to unlock the rest of the game. Early games shortly after the introduction of the in-app purchase feature used this approach such as ''

'' and '' Fruit Ninja''. ;Free-to-play :A free-to-play game requires no cost at all to play, and generally is designed to be playable from start to finish without having to spend any money into the game. However, the game will include gameplay mechanics which may slow progress towards completing the game. Commonly in mobile games, this is some form of energy or stamina that limits how many turns or actions a player can take each day. By using in-app purchases, the player can immediately restore their energy or stamina and continue on. In-app purchases can also be used to buy power-ups and other items to give the player a limited-time advantage to help complete the game. While free-to-play games had been common on computers prior to mobile, the method was popularized in mobile gaming with ''

'' and '' Puzzle & Dragons''. AppfloodFullScreenInterstitial

;Advertising-supported :A ad-supported game will be free to download and play, but periodically or persistently, the game will show an

advertisement Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to put a product or service in the spotlight in hopes of drawing it attention from consumers. It is typically used to promote a ...

to the user which they will have to watch through before they can continue with the game. The developer earns revenue from the advertising network. In some cases, an in-app purchase allows the player to fully disable ads in these games. ;Subscription model :A subscription-based game will offer a base version with limited features that can be played for free, but additional premium features can be obtained if the user pays a monthly subscription fee. If they terminate their subscription, they lose access to those features, though typically not any game progression related to those features, and can pick up those features later by restarting their subscription. Many game apps are free to play through a combination of these models. Over time, mobile developers of these types of apps have observed that the bulk of their players do not spend any funds on their game, but instead revenues are generated from a small fraction, typically under 10% of their total players. Further, most of the revenue is generated by a very small fraction, about 2%, of the total players, who routinely spend large amounts of money on the game. A similar split on revenue had been seen in social-network games played in browsers. These players are known as "whales", inspired by same term used for high rolling gamblers. The social nature of a mobile game has also been found to affect its revenue, as games that encourage players to work in teams or clans will lead to increased spending from engaged players.

Common limits of mobile games

Mobile games tend to be small in scope (in relation to mainstream PC and console games) and many prioritize innovative design and ease of play over visual spectacle. Storage and memory limitations (sometimes dictated at the platform level) place constraints on file size that presently rule out the direct migration of many modern PC and console games to mobile. One major problem for developers and publishers of mobile games is describing a game in such detail that it gives the customer enough information to make a purchasing decision.

Location-based mobile games

s. These are not only played on mobile hardware but also integrate the player's position into the game concept. In other words, while it does not matter for a normal mobile game where exactly the player is (play them anywhere at any time), the player's coordinate and movement are the main elements in a location-based mobile game. A well known example is the treasure hunt game ''Geocaching'', which can be played on any mobile device with integrated or external GPS receiver. External GPS receivers are usually connected via Bluetooth. More and more mobile phones with integrated

are expected to come. Several other location-based mobile games, such as '' BotFighters'', are in the stage of research prototypes rather than being commercial successes. Location-based mobile games sometimes have augmented reality functionality, such as in the case of Pokemon Go. Usually in these cases the augmented reality functionality is not at the center of the experience.

Augmented reality games

Mobile devices have been used as a platform for Augmented reality (AR in short) games, using the device's camera(s) to as an input for the game. While playing the game, the player aims the device's camera at a location and through the device's screen, sees the area captured by the camera plus computer-generated graphics atop it, augmenting the display and then allowing the player to

that way. The graphics are generally drawn as to make the generated image appear to be part of the captured background, and will be rendered app memorizing as the player moves the device around. The most successful and notable example for a mobile game that has an augmented reality feature is '' Pokémon Go'' (2016), where the player travels to locations marked on their GPS map and then can enable the augmented reality mode to find Pokémon creatures to capture. However, as of January 2022 there has been a lack of significant AR mobile games success since, with several AR mobile game projects being shut down, such as Microsoft's

Multipurpose games

in hospitals (Finnish startup Rehaboo!), acquiring new useful or healthy habits ( Habitica), memorizing things and learning languages ( Memrise). There are also apps with similar purposes which are not games per se, in this case, they are called ''gamified apps''. Sometimes it is difficult to draw a line between multipurpose games and gamified apps.

Multiplayer mobile games

Many mobile games support multiple players, either remotely over a network or locally via Wi-Fi, Bluetooth or similar technology. There are several options for playing multiplayer games on mobile phones: live synchronous

In asynchronous tournaments, there are two methods used by game developers centered around the idea that players matches are recorded and then

at a later time to other players in the same tournament. Asynchronous gameplay resolves the issue of needing players to have a continuous live connection. This gameplay is different since players take individual turns in the game, therefore allowing players to continue playing against human opponents. This is done using different networks including Facebook. Some companies use a regular turn-based system where the end results are posted so all the players can see who won the tournament. Other companies take screen recordings of live players and broadcast them to other players at a later point in time to allow players to feel that they are always interacting with another human opponent.

Distribution

Mobile games can be distributed in one of four ways: *

, and Microsoft Windows Phone, the mobile OS developers themselves have launched digital download storefronts that can be run on the devices using the OS or from software used on PCs. These storefronts (like Apple's iOS App Store) act as centralized digital download services from which a variety of entertainment media and software can be downloaded, including games and nowadays majority of games are distributed through them. The popularity of mobile games has increased in the 2000s, as over US$3 billion worth of games were sold in 2007 internationally, and projected annual growth of over 40%. Ownership of a smartphone alone increases the likelihood that a consumer will play mobile games. Over 90% of smartphone users play a mobile game at least once a week.
