How to play Flip
Pressing a tile changes that tile and its orthogonal neighbours. Find the short sequence that leaves the entire field dark.
On this sample: Tap a lit or unlit tile to flip its cross.
- A move toggles the selected tile and the tiles directly above, below, left, and right.
- Corners affect three tiles, edges affect four, and center tiles affect five.
- Finish when every light is off.
