Oskar van Deventer

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

  • Gear cube: Previously named "Caution Cube" because there was a big chance to pinch your fingers with the gears.[9] It was mass-produced by Mèffert's in 2010,[10] 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 mass-produced by Mèffert's in 2010,[11] and was also copied by other companies.
  • Gear Shift: It was mass-produced by Mèffert's in 2011[12]; a knock off version also appeared.
  • David Gear Cube: Previously called "Polo cube" in reference to Alex Polonsky, who had the idea.[13] It was mass-produced By Mèffert's in 2013.[14]
  • Geared 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 mass-produced by Mèffert's in 2014.[15]
  • Geared 5×5×5: An unknown Chinese company mass-produced this puzzle in 2015 using a 3D printed sample, without the permission of Oskar. An agreement was met to please both sides.[16]
  • Gear Ball: A mass-produced spherical Gear cube made by Mèffert's.[17]
  • 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 mass-produced by Mèffert's in 2010.[18]
  • Planets puzzle: Four balls in a frame. Craters on the balls block and unblock movement on the adjacent balls.
  • Rob's Pyraminx: It was mass-produced by Mèffert's in 2014.[19]
  • Rob's Octahedron: It was mass-produced by Mèffert's in 2015.[20]
  • 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 mass-produced by WitEden.[21]
  • Treasure chest: A 3×3×3 puzzle that when solved, can be opened, revealing a small chamber inside. It was mass-produced by Mèffert's.[22]
  • Icosaix: A face turning icosahedron with jumbling movements. It was mass-produced by MF8 in 2015.[23]
  • Crazy Comet: Was mass-produced by LanLan without Oskar's permission in 2016 but a deal was archived later.[24]
