SquareGri: Lights Out Puzzle

Tap a square and its neighbours flip colour. Your goal: get the entire grid to a single colour in as few moves as possible. It's the classic lights out puzzle, rebuilt with a clean, minimalist design - easy to learn, genuinely hard to master.

HOW TO PLAY
Every tap flips the colour of the tile you touch and of the four tiles around it. Sounds simple. Then you notice that fixing one corner breaks another, and it turns into a proper logic puzzle. Nothing here is down to luck - every grid can be solved, and every solution rewards clear thinking.

THREE WAYS TO PLAY

Classic
A fresh 8x5 puzzle every time you play. No timer, no pressure - just you and the lowest move count you can manage.

Time Attack
Race the clock. Solve the grid as fast as you can, pause whenever life gets in the way, and hunt down your best time.

Daily Challenge
One unique brain teaser a day, the same puzzle for everyone. A single attempt. No resets, no second chances.
