The 1st time I encounted these was in a science exam of all places! I found out more after and found the logic problem books and started to collect them. They are great but do not get put off if it seems hard, you may have to restart reading the clues a 2nd or 3rd time to get to the end. Simple, Addictive, Challenging & Fun. Update: Many puzzles are no longer logical and you have to make wild guesses as the clues are poor, even looking at the answers makes no sense to how they got thre.

Send us a screenshot of something you deem illogical. I’m confident we can explain how it is logical. Penny Dell do an amazing job with these puzzles (that we license) and I’ve yet to find a substantive error despite many claims like these. So, please give us a chance to either explain (or possibly correct)! Thanks. Email [email protected]

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.

This is my favorite variety of logic puzzle, the "classic" puzzle I'd always seek in those multi-puzzle books at newsstands. That said, sometimes certain authors use confusing clues, and occasionally I'd like to use the logic clues it says it has available, however, they are *not* available. Ever. I thought maybe I'd just progressed too far for clues to help, but even if i try it on a blank board it still says "no logic solutions are available". The quick version has them, just not this one. :(

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.
