🐱 MeowTrail: Cat Logic Puzzle — Light Up the Grid

What is MeowTrail?

MeowTrail is a cat-themed logic puzzle game based on the classic Akari (Light Up) puzzle by Nikoli. Place glowing cats on a grid to illuminate every white cell, following numbered clues on black walls. No two cats can see each other in the same row or column.

How to Play

1. Click a white cell to place or remove a glowing cat.
2. Each cat illuminates its entire row and column until blocked by a black wall.
3. Numbered black cells show how many adjacent (up/down/left/right) cells must contain cats.
4. No two cats can see each other — if two are in the same row or column with no wall between, that's illegal.
5. All white cells must be illuminated to win.

Double-click (or right-click / long-press on mobile) to mark a cell with a paw print — useful for noting cells you know can't have cats.

Difficulty Levels

• Easy (7×7) — Perfect for beginners. More numbered clues, simpler deduction chains.
• Medium (10×10) — The standard challenge. Requires intermediate techniques like cross-hatching.
• Hard (12×12) — For experienced puzzlers. Fewer clues, deeper reasoning required.

Tips & Strategy

Start with extremes

• "4" cells — all four neighbors must be cats. Place them immediately.
• "0" cells — none of its neighbors can have cats. Mark them with paw prints.

Use line-of-sight

• Once you place a cat, every cell in its row and column (until a wall) is automatically lit and cannot hold another cat.
• Look for cells that can only be lit from one direction — those are forced placements.
