How to play the Lights Out Puzzle
Some tiles on the board are lit. Tap a tile to flip it, along with the tiles directly above, below, left and right of it. Lit tiles turn off and dark tiles turn on.
Turn every light off to solve the puzzle. A counter shows your moves next to the par for that board.
Pick any puzzle from the list at the top. Reset puts the current board back to its start, and Hint points to a tile worth tapping next.
Puzzles and par
| Difficulty | Puzzles | Board |
|---|---|---|
| Easy | 3 | 3×3 |
| Medium | 3 | 4×4 |
| Hard | 3 | 5×5 |
Each board was made by pressing a set of tiles on a dark grid, so it can always be cleared by pressing those same tiles again. Par is the size of that set, from 1 press on the first puzzle to 7 on the last.
Clearing a board earns a reward, with more for harder boards. Solve it in par or fewer moves for an under-par bonus. There is no timer and no move limit.
Lights Out tips
- Tapping the same tile twice undoes it, so each tile needs to be tapped at most once.
- The order of taps does not matter. Only which tiles you tap changes the result.
- Chase the lights down: for each lit tile in the top row, tap the tile right below it. Repeat row by row until only the bottom row has lights left.
- The bottom-row pattern you end up with tells you which top-row tiles to tap first. Try a few top-row taps, then chase down again.
- Look for symmetry. Many boards here are symmetrical, and so are their solutions.
