About the game
One touch changes a crystal and its four direct neighbours. Find the right sequence and bring the entire board to life. Every starting pattern is solvable.
Choose 4 × 4 or 5 × 5 crystals. A star can show you a helpful move; every hint is counted alongside your moves and active play time.
The puzzle is complete when every crystal glows. Take your time: there is no countdown and no penalty for trying an idea.
