Hi, I’m Maik. I made LumoFlip, a free logic puzzle for Android. Tap a light and it flips along with its neighbours. The goal is to turn every light off. Finding a solution in fewer moves is where it gets interesting.

The campaign has 360 levels, from square grids to irregular boards and puzzles with two layers to clear. There’s also a daily challenge if you want a new board to try.

Visit the LumoFlip page on itch.io for the free Google Play download. You can play in English or German.

If you try it, I’d like to know whether the jump from one layer to two felt natural. Did the game give you enough time to get the hang of it?
