Well I suppose after 1,000 hours I've played enough to write a review. ;-)

This is the Ultimate jigsaw puzzle game on Steam. For one thing, it's FREE! And not only the program is free but they also give you quite a few free puzzles so you can try it out and see if you like it. Then, if you do like the game, there are tons of DLC puzzle packs to buy, each with a theme like Halloween, Christmas, Trains, and for the dudes who think puzzle games are lame they have Pin-Up Girls (ooo-la-la!). You can pick which theme interests you and only buy those. Or be like me and just buy them all. Piece size ranges from 100 to 1,000, though most of the time they are in the 200-300 range with a couple bigger ones like 450, 640. And the pieces themselves have weird cut-out shapes on some of the puzzles. They are not always the traditional cut-out shape. That could be a pro or con depending on if you like variety or would rather just stick with the traditional style.

Features:

Play the way you want to play. There are settings for how fast the pieces float in the river, and if they rotate, and other things I've forgotten.
There are different backgrounds behind the puzzle that you can choose from, so you're not stuck with the koi pond.
Kiosk! You earn stars and gold which you can use to buy a variety of cursors, headers for the main page, and unique puzzles in shapes!, plus some extra puzzles.
Every month there is a Challenge Puzzle. And some of them have been quite the challenge. 640-1,000 piece range. I tend to use a lot of cheats.
Oh, I haven't mentioned the cheats before! There are 3 of them: Flash image of entire picture for a few seconds, Show the location of the piece you are holding, and...something I've forgotten. You use the blue stars for the cheats, and each has a different number of stars they cost.
Music tracks to choose from (I turn off the music because I listen to podcasts while I'm puzzling)
You can replay a puzzle that you have finished, like if a family member wants to do a puzzle you have done.

Achievement hunters, I got bad news for you. You'll probably never 100% this game. Because there are achievements for each puzzle in each pack, and they keep adding packs once in a while throughout the year. Unless you spend your entire day doing puzzles you'll never come close to 100%.

So tldr:
It's FREE with lots of FREE puzzles to do
DLC Puzzle Packs that have themes - buy the ones you like
Lots of customizable settings
There are a few puzzles with a FROG as the subject, so there you go that's all you need to insta-buy! P-)
Did I mention it's FREE? Just download it and try it out. You will become a pixel puzzle addict like me (I play every day. No joke. Every. Day!!!)
