How to play
01 · Touch
Tap any cube on the lattice.
02 · The cross
That cube flips — and so do the ones above, below, left and right of it.
03 · Light & dark
Lit cubes glow cold blue. Dark cubes stay dim. Each flip switches both states.
04 · The goal
Light every cube. Plan ahead: one careless tap can undo three good ones.
05 · New
Stuck? Start a fresh solvable lattice. Every board can be cleared.
