Lights Out Lab

Flip the switches. Turn every light off.

Tap a switch and it flips a shape of lights. Turn every light off to clear the lab. The shape changes as you go, from a two-light domino to a chess knight's jump. No timer, no fail state.

  • 40 hand-tuned starter labs
  • New switch shapes as you go
  • Endless generated waves
  • Undo and restart are always free
