About this game

Train your brain with Logic Grid Puzzles — the #1 logic puzzle app with no ads! Use deductive reasoning to follow clues, eliminate answers, and solve satisfying grid puzzles. Perfect for brain training offline — no wifi needed.

Start with small 3×4 puzzles or challenge yourself with huge 4×7 grids. 100 free puzzles of increasing difficulty will take you from beginner to master.

SMART HINTS that teach, not just tell
Stuck on a puzzle? Smart Hints examine your solution so far and explain how to fill in another cell — referencing your current board and telling you what clue to use next (internet access required). Your brain will love the extra training this provides.

DESIGNED FOR FAST, FOCUSED PLAY
Auto-X for faster entry, multi-level Undo, error checking, adjustable text size, and Dark Mode. Everything you need to focus on the logic.

MORE PUZZLES WHEN YOU'RE READY
Purchase extra volumes with 100 new puzzles each, or unlock over 19,000 puzzles of all sizes with the optional monthly subscription. It renews automatically unless you cancel at least 24 hours before the end of the monthly period. Manage or cancel anytime in your Google Play account settings or the app's Manage button.

If you enjoy brain teasers, deductive reasoning, zebra puzzles, or Einstein puzzles, Logic Grid Puzzles is for you.

Gives you exactly what you want and no annoying extras. No ads between each puzzle, nothing to purchase but more puzzles. I've bought two extra packs, and then caved and got the unlimited puzzles too. It's worth it. I was sick of playing mindless games on my phone that just made me feel worse about wasting time. At least with this I can feel like I've done something good for my brain!

Thanks so much for your thoughtful review. Yes, philosophically we just can't publish brain puzzles that then rot your brain's attention with ads. Thanks for supporting us in this quest with your puzzle purchases and recent subscription! Check out our other games for a similar experience (e.g. Star Battles for a "meowdoku" type of puzzle). Thanks!

Phenomenal game! I love that crossed out items go to the bottom of the list now. Wow!

What’s new

The app now remembers where you were, even after your phone puts it to sleep. Switch apps, come back, and you'll land right in your puzzle, not the main screen looking for the started puzzle, or scrolling to find your favorite section. "Next Puzzle" works every time too.

As always, email support@eggheadgames.com any time with questions or suggestions. We love to hear from you!
