What’s new

Version 2.0.7 · Updated September 11, 2026

A locked line can be unlocked again. Holding a completed line's target locks the whole line. Nothing used to undo that — and a line can be right on its own while the rest of the board cannot live with it, which left the grid looking unsolvable. The same hold now frees the line, and the board's "?" explains both. Thanks to the player who reported it. — The Rullo Team

It real gets you're brain moving, and has a nice minimalist design. The game is pretty fun for an offline game. There were less ads than I expected, which is why I rated it 5 stars

I love this game, but suddenly I'm constantly interrupted by a message that the certificate isn't trusted. Please fix!

Fantastic game! I have had it for close to 3 years.👏 I was on level 7603 on Endless until my aunt uninstalled it a few moments ago 😞

Soothing and sometimes challenging but also my forever go-to for relaxing my buzzing mind when I cannot sleep. This is the only game on my phone I will never delete. Simple, calming, aesthetically pleasing and it even sounds satisfying.
