Oskar van Deventer is a Dutch puzzle maker.[1] He prototypes puzzles using 3D printing. His work combines mathematics, physics, and design, and he collaborates at academic institutions.[2][3][4] Many of his combination puzzles are in mass production by Uwe Mèffert and WitEden. Oskar van Deventer has also designed puzzles for Hanayama. He was a Guinness World Record holder for his 17×17×17 "Over the Top Cube" Rubik's cube-style puzzle from 2012 to 2016,[5][6] when it was beaten by a 22×22×22 cube.[7] In addition to being a puzzle maker, Oskar is a research scientist in the area of media networking and holds a Ph.D. in optics. He has over 100 publications, over 50 patents applications, and hundreds of standardization contributions.[8]

Mass produced puzzles[edit]

Gear cube: previously named "Caution Cube" because there was[clarification needed] a big chance to pinch your fingers with the gears. It was[when?] mass-produced by Mèffert's, but over time it appeared as several copies and shape mods of the same design. Gear cube extreme: a bandaged version of the Gear cube, where 4 gears are replaced for 4 standard edges, making the puzzle harder. It was[when?] mass-produced by Mèffert's, and was also copied by other companies. Gear Shift: It was[when?] mass-produced by Mèffert's; a knock off version also appeared. David Gear cube: previously called "Polo cube" in reference to Alex Polonsky, who had the idea. It was[when?] mass-produced By Mèffert's. Gear Mixup: a variant of the gear cube where all faces can perform 90° rotations, allowing centers to be interchanged with edges, hence the term "mixup". It was[when?] mass-produced by Mèffert's. Gear 5×5: An unknown Chinese company mass-produced this puzzle using a 3D printed sample, without the permission of Oskar. An agreement was met to please both sides. Gear Ball: A mass-produced spherical Gear cube made by Mèffert's. Mosaic cube: previously called "Fadi cube", it is a corner turning puzzle with two cut depths similar to Okamoto and Greg's "lattice cube". It was[when?] mass-produced by Mèffert's. Planets puzzle: Four balls in a frame. Craters on the balls block and unblock movement on the adjacent balls. Rob's Pyraminx: It was[when?] mass-produced by Mèffert's. Rob's Octahedron: It was[when?] mass-produced by Mèffert's. Mixup cube: a 3×3×3 Rubik's cube that can perform 45° rotations on the middle layers, allowing centers interchange with edges. It was[when?] mass-produced by WitEden. Treasure chest: A 3×3×3 puzzle that when solved, can be opened, revealing a small chamber inside. It was[when?] mass-produced by Mèffert's. 1x2x9: A special puzzle for the Jade club. It was[when?] mass-produced by Mèffert's. Icosaix: a face turning icosahedron. It has jumbling movements.[clarification needed] It was[when?] mass-produced by MF8. Crazy Comet: Was[when?] mass-produced by LanLan without Oskar's permission. A deal was archived later[when?] (At this time Dayan had already shown a prototype). Redi Cube: A corner turning puzzle mass produced by Moyu.
