About this game

Light Up

Tap a cell and a light switches on, shining up, down, left and right until
a wall stops it. Fill every dark cell — but never let two lights see each
other. Numbered walls tell you exactly how many lights may touch them.

WHAT YOU GET
- Campaign mode
- Sprint mode
- 1000 boards — every one falls to pure deduction
- Never a guess. If you are stuck, there is always a next forced move
- The first four boards teach the rules one at a time, on the board
- Two lights in the same line turn red immediately
- Long-press to mark a cell you have ruled out
- Unlimited free undo — the Campaign has no timer and no lives
- Plays offline, no account needed

Sprint mode adds a three-minute clock if you want one — and builds a fresh
board every round, so no two runs are the same. Campaign never uses a clock.

Free to play with ads. No purchases required.
