Place mirrors inside the grid to guide the beam of light
so it hits every target.
You have a limited number of mirrors.
No time pressure — score is based on how few attempts you need.
Place mirrors on a grid to redirect a beam of light through every teal star target. Solve all 15 puzzles with as few wrong attempts as possible.
Tap any empty cell to place a / mirror. Tap again to switch to a \ mirror. Tap a third time to remove it. The beam bounces off mirrors at 90°.
Each puzzle starts at 500 points. You lose 30 pts per wrong attempt and 60 pts per hint used. Solve cleanly to maximise your score.
Mentally rotating and reflecting beam paths builds the same spatial skills used in engineering, navigation, and 3D problem-solving.
Each mirror placement affects all subsequent beam angles — training multi-step forward planning and consequence evaluation.
