How to play

Every receiver shows three dots for red, green and blue. Light it with exactly the colours it asks for: filled dots are wanted, rings are arriving now.

Beams add up where they meet: red + green = yellow, red + blue = magenta, green + blue = cyan, all three = white.
A mirror bends a beam 90°. It has two angles.
A splitter lets the beam through and also bends a copy.
A filter keeps only its own colour. A prism fans a beam that enters its flat back into red (left), green (straight) and blue (right).
Walls and board edges swallow light. Too much of the wrong colour also fails.
Fewer moves earn more stars.
