Do you like the ...tris kind of block puzzle games? Then you must check this out. In this immersive puzzle game you stack differently shaped blocks in a box. Complete layers will disappear. Sounds familiar? But this is in 3D! Beat the high scores in normal playing mode, relax in the non-competitive zen mode, or check out the daily missions. The game music adapts to the gameplay. It was recorded on real analog synthesizers from the seventies and eighties, creating an authentic retro experience. This app is not only great fun to play, but it also boosts your brain. A scientific study has shown a significant improvement of the spatial sense in teenagers playing a similar video game. ** Either play for free with ads or unlock the ad-free version as an in-game purchase.

Noss: Improvement of spatial sense in 10 to 14 year-olds by the video game Blockout, diploma thesis, Vienna University, 1994 (original German title: "Förderung der Raumvorstellung bei 10- bis 14-Jährigen durch das Computerspiel Blockout"). In this study with more than 100 kids, half of the kids got the opportunity to play Blockout (a block puzzle game quite similar to qubotron) during summer vacation, the other half did not. The spatial sense of all kids was tested before and after the vacation using a standard test procedure (Gittler 3DW Test). The kids having played the game improved significantly compared to the kids not having played the game.
