Sherlock: Grid Solver

Sherlock: Grid Solver — Logic-Grid Deduction Puzzles

Put on your detective hat and crack the case with pure logic. Sherlock: Grid Solver is a classic logic-grid puzzle game (the kind sometimes called a "logic problem" or "zebra puzzle") wrapped in a cozy whodunit. Read the clues, rule out what can't be true, and deduce exactly who did what — no guessing required.

HOW IT PLAYS
Every case gives you a cast of suspects and a handful of clues. Tap a square to place a tick (✓ confirmed) and the squares that can't be true cross out (✗ eliminated) automatically. Chain the clues together, narrow the grid down, and unmask the culprit. If your reasoning is sound, there's always one — and only one — solution.

PUZZLES FOR EVERY MOOD
• Easy (3×3) — quick, friendly cases to warm up
• Medium (4×4) — a satisfying after-coffee challenge
• Hard (5×5) — twisty, clue-packed mysteries for seasoned sleuths
• Daily Puzzle — a fresh case every day, with streaks to keep alive
• Endless — unlimited, freshly generated puzzles so you never run out

SMART TOOLS, NO FRUSTRATION
• Pencil marks for jotting tentative "maybe" notes
• Pinch to zoom on the bigger grids
• Undo and Clear so you can explore freely
