all the additional puzzle packs went up a dollar in just a few months. if you want all the puzzles, I'd go ahead and buy them now because they're almost 4.50 for 20 puzzles with tax). in October it was 3.20. you get more value from buying their printed books at this point. also a few puzzles have typos

Hi, yes we did raise the price by $1 a few months ago for the first time since launching the app many many years ago. We have no plans to raise it again. 30 puzzles per pack, not 20. Happy puzzling! (Oh and please let us know about typos so we can fix them. Email support@eggheadgames.com for that or anything else.). Cheers, Michael

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 support@eggheadgames.com

This is an unprompted review: despite having never paid anything to use it, I have used this app, off-and-on, for several years. It is the only logic puzzle app I've tried that actually requires a fair amount of logical thinking (not just mindlessly checking boxes based on statements like "the Dr. had red hair; bob has brown hair"...etc. ). Because of this, even the "casual" puzzles are quite difficult & I don't actually 'remember' after solving, so I can replay every year or so.

What’s new

Crossed-out hints now move to the bottom of the clue list without losing the current position. A fix for a rare repeating launch crash.

We love to hear from you! Email support@eggheadgames.com and please include a screenshot if you have a specific question. Happy puzzling!
