Logic Grid Puzzles is the gold standard for deductive reasoning apps. It successfully takes the classic 'Zebra Puzzle' format and makes it feel modern and interactive. The highlight of the app is undoubtedly the 'Smart Hint' system. Instead of just giving you an answer, it actually explains the logic behind the next move, which helps you become a better solver over time.
The app is exceptionally clean—no ads, no nags, and a clear focus on the puzzles themselves. With 100 free puzzles and hundreds more available in packs, the value is incredible. The inclusion of accessibility features like VoiceOver support and Dark Mode shows a level of care that is rare in the puzzle genre. It’s an essential app for anyone who loves a good intellectual workout.

When a clue tells you two items are linked, place a checkmark. The app's 'Auto-X' feature will automatically fill the rest of that row and column with 'X's for you. If a clue says one item is NOT another, place an 'X'. Overlap these findings to narrow down the remaining possibilities.
Start with the small 3x4 puzzles to learn the basics. As you progress to larger 4x7 puzzles, you'll need to combine multiple clues to find the answer. Use the multi-level undo if you make a mistake, or check the grid for errors if you get completely stuck.
