A Chroma Ray stage with red, green and blue beams crossing the board

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.

1

Place

Tap an empty cell to place a piece from your inventory.

2

Rotate and move

Tap a piece to rotate it. Drag it to move it, or drag it off the board to take it back.

3

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.

Filter

Lets only its own color through.

Splitter

Sends light both straight ahead and to the side.

Prism

Splits light: red turns left, green goes straight, blue turns right.

Portal

Light leaves the portal with the same number, going the same way.

Inverter

Changes light to its opposite color. Red becomes cyan.

One-sided mirror

The bright side reflects. The dotted side blocks.

Combiner

Merges incoming light and sends it where the arrow points.

Switch door
