FOLLOW THE LIGHT

How to play.

Place and turn

Click or tap an empty cell to place a mirror. Tap the mirror to rotate it, or hold to remove it. Each reflection turns the beam by 90°.

Collect coins

Route the beam through coins on the board. If you get stuck, spend them on a hint that shows where to place or turn a mirror.

Work with the limits

Some puzzles limit your mirrors. Others make the light fade over distance or lose energy with each reflection. Try using fewer turns or a shorter path.
