About this game

Penny Dell magazine Logic Puzzles for the true logic problem fanatic. Try before you buy with the first ten puzzles included free with all features enabled and never any ads, nags or spyware. If you like it, thirteen more volumes are available for purchase, each with thirty unique puzzles, for hours of puzzling fun.

Keep your mind sharp with these stimulating logic problems that will exercise your brain muscles — a great introduction to deductive reasoning! Enjoy a range of problems in every volume.

No more erasing! Multi-level undo and Auto-X let you focus on the logic. If you get stuck, you can choose to erase errors, get a logical hint, or view the full hand-worked solution (just like the magazines).

Works best on larger screens, but you can zoom the grid to fit your screen - from phone size to the largest tablet.

Looking for harder puzzles? E.g. 7 cell grids? Try our Logic Puzzles app with puzzles by Puzzle Baron.

Love the game. With the update, though, once you use a hint, you can no longer undo anything. If I've made a mistake, I start erasing my answers one by one until the hint tells me I have no more mistakes. If you choose "erase mistakes", then it shows you where the correct answers should be, rather than letting you work through the logic again. Could there be a level of undo that clears the entire row and column of any mistakes? Or one that reverts back to the last error-free set of cells?

Tip for missing puzzles if you have multiple Google accts. Google no longer links multiple accts. My secondary account purchased extra puzzle packs, and app was linked to primary. This wasn't a problem until it was. To resolve this, you must access Google Play with your CURRENTLY linked acct to uninstall the app. Then, sign into your preferred account and download the app again. Review changed. I resolved my own problem, but they were prompt to reply and try to help from their end

Please get in touch by emailing support@eggheadgames.com. You should never lose any puzzles, whether from updating or any other reason. After this update to Google's latest Play code, the system does keep track which Android used purchased the puzzles and that has caused some people some hassle. We'll help you through it. Thx, Michael

Exactly what I was looking for. You can scroll through the clues while still viewing the grid. I've played another one where you couldn't see the grid while viewing the clues and I didn't like that. I've seen reviews saying they aren't solvable with the clues, but that is not true. Some of them are just really challenging. A difficulty label would help. There are no ads and you can do 10 free puzzles to see how you like it before ever paying. I think $3 for a pack of 30 is pretty reasonable.
