You all should play Chuzzle 2. It's an app game where you play different Chuzzle challenges at each level, go in the bottles to get bonuses, earn coins, get the jigsaw puzzle pieces in the Puzzle Room, unlock the cutest Chuzzle pets to put in your Chuzzarium, add enrichment, food, and treats for your pets. You can get a Trophy Room, a Zen game, Speed Chuzzle, and Classic Chuzzle, and when you fail or decide to go back to level one, you'll unlock the Daily Do that you can do everyday. Don't worry, the Chuzzle pets don't disappear when you go back to level one.
By the way, you'll get something called Seasonal/Event Jigsaw Puzzles where it only lasts during that month/season. They'll disappear until the event returns back, or they might stay if you place one piece on the board.
Play the game, and have fun. By the way, there are ads you have to go through, yet the app game - soon be on PC according to the new update by the developers - is a great thing to play.
Another thing is that it does get harder on each level, too.
