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.

Verdict

The call

The clearest difference is ratings volume: Linea at 424 against qubotron's 5. Linea also leads on rating (4.5 vs 4.2). qubotron's advantage is review sentiment (67% vs 50%) and update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. qubotron sells 1 one-off in-app purchase and Linea sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Linea holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Linea has 424 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of qubotron's written reviews are positive against 50% of Linea's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

qubotron ships an update weekly, Linea every 3 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
