Logic Grid Puzzles
No Ads, Smart Hints, Easy-Hard
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Learn and enjoy Logic Problems with 100 unique puzzles of increasing difficulty and multiple sizes. Decode written clues & fill in the grid to solve each puzzle. Work your way up from from beginner to master! Use the unlimited Smart Hints to see exactly which clue applies to the current board and why. Start with small 3×4 puzzles and challenge yourself with huge 4×7 cell puzzles.
Smart Hints examine your solution so far and explain how to fill in another cell by referencing your current board position and telling you what clue to use next (internet access required).
Other features include Auto-X for faster entry and multi-level Undo. These make it easier and quicker to focus on the logic! If you're completely stuck, you have the ability to check the grid for errors.
There are never any ads or nags or gimmicks. The app supports iOS iCloud sync and accessibility features, including VoiceOver, Larger Text and Dark Mode.
If you run out of puzzles, there are multiple "100 packs" of new puzzles available for purchase. These are in the same size & quantity as the original free puzzles: 30 each of 3×4 & 30 3×5, and 10 each of 4×4, 4×5, 4×6 & 4×7.
Alternatively, you can purchase an Unlimited Puzzles monthly subscription for £4.49 per month (or similar for your country).
Subscription payment will be charged to your iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Account will be charged for renewal at the same price as the initial month within 24-hours prior to the end of the current period. Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user’s Account Settings after purchase or using the “Manage Subscriptions” link. There is no free trial.

Reverts the recent change to row/column highlighting based on vociferous customer feedback! The original change was only meant to affect individual hint cells, to make dark mode clearer, but we didn't fully consider the row/column implications. Sorry about that. Many thanks to those customers who emailed us with their feedback. (We take your feedback especially seriously because we're paid directly by you, not advertisers, like most apps these days!)

5.1.1 03/08/2024
Adds the optional display of expert time when completing a puzzle. This has been asked for many times by curious puzzlers who want to know "how close did I get to expert?" This can be disabled anytime, along with all references to hints and timing in other places in the app (simplifying the prior Zen Mode feature). The app also takes up 5% less space after some spring cleaning.
