Really challenges your logical thinking

Very simple game but challenging at all levels. Solving a "hard" puzzle is very satisfying. And very well designed, like all Conceptis apps.

Ótimo

Nice app

Very fun to use, np ads

Please add more levels😭😭🙏🙏🙏🙏🙏

I am so absolutely obsessed with this game. I’ve played every day for months if not over a year I’m not even sure. I play so much that I see it when I close my eyes. I’ve replayed all of the hard starter levels probably a hundred times. I am begging you pleaseeeee add more levelssss 🙏🙏🙏😩😩😩😩

Dark mode thank you so much

I am currently feeling an indescribable level of gratitude at discovering you have not only instituted dark mode, but that it functions inside the actual puzzle (which I’m pretty sure another conceptis puzzle did not manage to do. Understandably given the colour basis of it but still).

Like, genuinely. It hurts so much less. Thank you.

This puzzle game has helped keep me sane for a long while now, and now it doesn’t hurt.

Today was a bad day and this helped make it better.
