How this data is usedHelp
Tap a mirror to turn it. The arrow marks the light source, numbered circles are checkpoints, and the square is the receiver. Brick-pattern blocks are walls: they stop the light and cannot be turned. Choose Check to see its path.
Each mirror turns light through a right angle. Checkpoints let it pass straight through and may be reached in any order. You can leave extra mirrors unused; every valid route is accepted.
On the board, arrow keys move between mirrors. Space or Enter turns the focused mirror. On a phone, the lettered buttons below the board turn the matching mirrors.
