Brain Lightener: Logic Puzzle

Light up every tile. Sounds easy? Every tap flips a tile and its neighbors, so each move changes the whole board. Brain Lightener is a lights-out style logic puzzle that is quick to learn and truly challenging to master.

Start with tiny 3×3 boards and work up to big 7×7 brain teasers, picture puzzles, boards that wrap around like a globe and twin boards that flip together. Every puzzle has a proven solution, and stars reward you for matching the fewest possible moves.
