Lightfall

Light every crystal before the water takes the room.

You've got a beam of light, a handful of mirrors and a room that's slowly flooding. Bounce the beam onto every crystal before the water drowns your pieces. Too slow, and the water gets there first.

A new room every day

Every day there's a Daily Room, the same puzzle for everyone. Solve it, post your time and see where you land on the leaderboard. Or just play it quietly. You never have to send a score.

80 rooms, with more on the way

Ten groups, each with its own trick: mirrors, splitters, darkness, colour, distance, panes and water, switches, portals, afterglow and moving parts. Each group teaches one idea, then makes you combine it with everything you've learned. More rooms are added all the time.

Five places to flood

A drowned lighthouse, a sunken temple, a wrecked ship, an old mine and a deep cave.
