About this 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.

Just what I was looking for to kill time at work. I love logic grids. I will say that the "expert" time is definitely made up. Im not the sharpest tool in the shed, but there's no way expert time on the 4x4 grids is clocked at 19 seconds when it took me just over 6 minutes to solve with my undivided attention. Especially with the vague hints that are given. Aside from that, this game is money.

I loved logic puzzles as a kid, so I wanted to get back into them. this app is awesome, but it does get a little too difficult as you get further in. they're naturally going to take a little getting used to again, and the puzzles are purposely progressively more difficult, but it gets to the point that the clues you're given aren't enough to complete the puzzle without guessing — which is not why I'm here. I'm trying to use puzzle logic to solve the logic puzzle.

I know that sometimes it can feel like the clues are insufficient, but if you tap Suggest Move, it will give you a hint which shows you which clue and board position has more information about how to solve the next square logically. I.e. there is always a logical next move. Email support@eggheadgames.com if the hint is unclear. Happy puzzling!

edit: just bought my 11th package! love this game! I have really enjoyed this, even enough to purchase the second package when I ran out of the freebie. I do find that some of them look at the logic very differently than others and not in a way that makes sense to me even though I'm pretty analytical. that being said I just ran out of my first paid and I'm about to buy more and I'm really cheap so that should say a lot!

Yes, they can be deceivingly logical, & then there will be one that just makes my mind turn inside out! Look at the link in the Guide called "How to Solve Logic Puzzles" for some really interesting strategies. Some can be found by just looking for patterns in the grid, and others are more nuanced. Thanks for buying more (& you can replay them too).
