About Logic Grid Puzzles: Brain Game

Enjoy Logic Puzzles with 100 unique brain puzzles of increasing difficulty and multiple sizes with no ads. These logic puzzles will keep your brain active and improve your cognitive skills. Smart Hints will teach your brain how to play and help your brain learn new patterns. Use the clues to fill in the grid and solve each logic puzzle. Work your way up from from a logic puzzle beginner to master! Use unlimited Smart Hints to see exactly which clue applies to the current board and why. Start with small 3×4 logic puzzles or challenge your brain 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). Your brain will love the extra training this provides.

Other features include Auto-X for faster entry and multi-level Undo. These make it easier and quicker for your brain cells to focus on the logic! If you're completely stuck, you can check the grid for errors.

Logic puzzles supports modern Android features like adjustable text size and Dark Mode.

For more puzzles, you can purchase extra volumes each with 100 new puzzles of the same sizes as in the initial app. Alternatively, the optional monthly subscription unlocks 10,000 puzzles of all sizes. It will automatically renew unless you cancel at least 24 hours before the end of the monthly period. You can manage or cancel your subscription anytime in your Google Play account settings or using the Manage button in the app.

it is a cool thinking game. You have to solve the puzzles by using the hints that are given to you. so far not that much ads but this is all my first take of it so my opinion may change later on.

I've only done a few of the "extreme" ones and like it so far. Unique topics which are fun but the grid is a bit chaotic sometimes, especially on the phone so I redrew it on paper. No ads. Could be a lot more challenging though so I don't have any hopes for the earlier tiers to be for me. But in general the app seems super well done.

Fun logic puzzles. I had an issue where I was 2 moves from the end of a puzzle when it suddenly exited to the puzzle type choice screen (the main one with all the circular icons) and when I clicked back to the puzzle I was solving, it had been completely wiped clean. I tried to restore it by pressing undo, then by going to recent apps and reloading, but nothing changed. Kind of annoying to have to redo the full puzzle at that point.

Fun game but the same style of riddle.

Puzzles are fine, BUT the ENGLISH GRAMMAR IS HORRID. I am a writer and editor, and so beware. You will have to pretend you're reading a PENNY Logic magazine written by PROFESSIONAL WRITERS, and just assume what they mean and NOT what they say. Grrrrrr hire some English editors.

Minimal ads, clean display, easy to use, large library of free puzzles (which you can clear if you want to start them all again) with the ability to purchase additional puzzles for a couple £ (or monthly subscription). A decent, classic game like they used to be.

Expert levels are hard enough to really make my brain work! Loved these as a kid and appreciate this now. Price is more than fair, especially since there are never any ads. Thank you!
