Light On - Logic Puzzle Game

Light On is a brain-teasing logic puzzle game inspired by the World Puzzle Championships. Place light items on a grid divided into irregular colorful regions. Three simple rules: one item per region, one per row, one per column, and no two items can be adjacent — not even diagonally. Easy to learn, endlessly challenging.

ENDLESS MODE
Challenge yourself in endless mode with randomly generated puzzles. Grid sizes range from 5x5 to 10x10 with natural difficulty fluctuation — every board is a fresh brain teaser that tests your logic and deduction skills.

COLORFUL PUZZLE GRIDS
Each grid features irregular regions painted in a pastel palette of 10 distinct colors. The vibrant visuals make every puzzle satisfying to solve and pleasant to look at.

INTUITIVE CONTROLS
Double tap to place an item, single tap to mark a cell as empty, and swipe to batch-mark multiple empty cells at once. Smooth, responsive controls designed for touch.

LIVES AND HINTS
A lives system adds real stakes — place an item wrong and lose a life. Revive by watching a rewarded ad or sharing with friends. Use hints when stuck to reveal a correct position with visual effects. Skip a level or generate a new board for a fresh start.
