Horribly addictive. Great zone out game without being boring. This game is a matching pictures games with the pictures being of dogs. Surprisingly clever with design of pictures making it a bit harder than it sounds. I am always looking for games which keep my interest but don't drive me nuts with impossible challenges or in game purchases. This certainly is straight forward and I haven't yet come across in game purchasing being required. There are several different types of game within this app so plenty to do.
All the 'istry' games are great to play, lose track of time trying to better your times, 6 different modes to play from timed to non-timed, stationary camera, highly recommend to anyone wanting a good game to play.
I must admit that I am not only a fan of dogs, but also a fan of this line of games. I already own Catistry and Zooistry. I can get lost in these puzzles for hours and I'm not sorry about it!! I love it and look forward to the next version being offered through the Free App of the Day from Amazon. There are no extra permissions, and this is just a fun and enjoyable game if you want to kill time and look at nice pictures of canines. You can't beat this as a free app, but this line of games is so enjoyable to me, that I am willing to pay real money for other versions. Great job by the app developers!
