One of the better slider puzzles, Poly Puzzle: Dogs manages not to overstay its welcome while being a decent challenge if you're after another completed game for your collection.

The polygonal style is largely why some puzzles are quite difficult in this, especially the dogs with majority brown or black coats. With the capped number of moves per puzzle you'll find yourself pausing to think often. You thankfully can reset each puzzle so the pieces cycle position and sometimes reveal their needed placement.

There are really only two negatives with this game. One, the soundtrack is irritating from the get-go and you'll probably turn it off quickly - but it re-enables itself each startup lol. Two, a minor complaint but difficulty whipsaws all through the puzzles until the last dozen, where you'll spend several minutes on each.

Achievement hunters, note this is yet another "Steam is learning about" title and as such is not counted towards your global completion at this time. You're looking at between 2 and 3 hours to 100% PP:D, every finished puzzle unlocks two achievements.

Easy recommend especially when on sale, due to limited replayability though I would not suggest a full price purchase.
