Original logic grid puzzles, a daily case and hints that explain every step.
Read the clues, mark the grid, crack the case. Logic Grid: Deduction Puzzles is a calm, clever puzzle game for people who love working things out. Every puzzle tells a short story: four neighbours share a garden, five runners finish a race, a prize pie goes missing from the fair. Each person goes with exactly one item from every list. Read the clues, cross off what can't be true, and the one answer appears. WHY YOU'LL LIKE IT - 400 levels in a smooth difficulty ramp, from three-list warm-ups to big five-list grids - A daily case: easy on Monday, a bigger puzzle every Sunday. Keep your streak going - Every puzzle has exactly one answer and can be solved by pure logic. No guessing, ever - Hints that teach: each hint names the clue it uses and explains the step. If a mark is wrong, the hint points it out first - 20 original stories: bake sales, dog shows, train stations, birdwatching, a lost property office and more MADE FOR A PHONE - Tap once for a cross, twice for a tick. A long press places a tick straight away - Auto-cross fills in the rest of a row and column for you (switch it off if you prefer) - Beginner mode: no notes needed. Place a tick and every cross that follows is filled in across all the grids - Tap a clue to strike it through once it's used up - Pinch to zoom on the big grids, undo as far back as you like, and pick up any puzzle where you left off - Works on tablets and with a keyboard too FAIR AND FREE - 3 free hints to start, then watch a short video for another, or remove ads once for unlimited hints - Plays offline: every puzzle is in the app New to logic grids?
