Logic Grid Puzzles
Every game generates a fresh puzzle with a unique solution. Use ✓ and ✗ marks to deduce how each category pairs up — every row and column must have exactly one ✓.
🧩 Logic Grid Puzzles
A classic deductive reasoning puzzle. Given a set of clues, figure out exactly how the items in each category correspond to one another.
🎯 Goal
Place exactly one ✓ in every row and column of the grid so that all clues are satisfied. Click a cell to cycle: ✓ → ✗ → empty. When you mark a ✓, its whole row and column are auto-crossed.
🕹️ How to Play
- Pick a difficulty — the harder the level, the more categories and items.
- Read the clues and mark ✓ where two items must go together, ✗ where they cannot.
- A ✓ automatically crosses out the rest of its row and column.
- When every row and column has exactly one ✓ and all clues hold, the puzzle is solved.
💡 Tips
- Start with clues that fix a pair directly — mark that ✓ right away.
- Use ✗ to eliminate impossibilities; a row with only one cell left must be a ✓.
- Keep the clue list visible and tick off clues as they are satisfied.
- If your marks become contradictory, press Hint to reveal a safe cell.
