Light adds up
Unlike paint, light gets brighter as it mixes. Turn the lights on and see what the crystal needs.
A crystal lights only when the color arriving is exactly its own.
Easy to pick up
Every control is a tap or a drag. The first stages show you the rest.
Place
Tap an empty cell to place a piece from your inventory.
Rotate and move
Tap a piece to rotate it. Drag it to move it, or drag it off the board to take it back.
Light every crystal
Clear with no hint and few moves to earn all three stars.
A new device keeps it fresh
Devices arrive one at a time, each with a short guide the first time you meet it.

Splitter
