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. After some first minutes of gameplay you will automatically asked for your choice. We put a lot of effort in making this game fun and easy to play.

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.

Verdict
The clearest difference is update cadence: qubotron at weekly against Roller Polar's every 9 months. Roller Polar's advantage is rating (4.3 vs 4.0) and ratings volume (62 vs 4). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Roller Polar sells 1 one-off in-app purchase and qubotron sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Roller Polar holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Roller Polar has 62 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 59% of Roller Polar's written reviews are positive against 67% of qubotron's, so the app with the better star average is not the one people write more warmly about.
Roller Polar ships an update every 9 months, qubotron weekly. The most recent releases landed on October 21, 2026 and October 8, 2026 respectively.
