A great word game

Really challenging and an exercise for the mind. A prettier interface and the ability to guess 4, 5, and 7 and 8 letter words would make it a five star review.

Excellent word game! Fresh idea.

I've had this game on my idevices for many years, and I always come back to it. Definitely gets your brain working!

Fun game, simple UI, great options for play! No ads or anything annoying. Really well developed!

Can be as challenging as you want: Can be incredibly difficult or nearly mindless, it's up to you. Just a truly fine game!

To the man I met at Epcot

I don't remember your name, but we talked in the England section in Epcot and you told me you had made a game, so I downloaded it and I love it! So hard but yet challenging and engaging. Thanks for the awesome app! :)

A great game!

I'm not sure what Bzur's problem is, or why he he says "it's a mess", but I'm also a long time user of Deduce, and the iOS 7 version is working just fine and has some fun new features (like Deduce Puzzles and advice from Sherlock). Overall it's a very unique and satisfying game!

It was fun once!

This game used to be fun. It is challenging to come up with 6 letter words. But about a week ago, there came about a glitch that didn't require real words - e.g., a guess of "AAAAAA" would go through - this totally took the challenge out of the game. Now I just updated and that glitch is fixed, but now the switch to allow already discarded letters doesn't work. Come on - it worked fine before and now it is a mess.
