Discover the most beautiful castles in the world in this solitaire and difference game. First, you must remove all the cards from the playing field. You can place a card on the stack that is one number higher or lower than the top card on the stack. For example, if the top card is a 2, you can click on any available 3 or A and then click on the stack or vice verse to place a card on the stack. If a card is covering one you need, click on the card in the way and then click on the temp space to move the card to the temp space. Once you've cleared the board, try to find all the differences between the 2 images. The faster you do it, the more bonus points you get. Finish that and move on to the next level. There are 10 levels total. If you're ready for a fun new challenge, play Castle Solitaire!
