While serious Solitaire players won't like how this takes liberties with their favorite card game, those looking for a new take on an old favorite will appreciate its creative approach. In Undersea Solitaire Tripeaks, you help a crab rebuilt his hometown by solving a series of Solitaire-esque card puzzles. Unlike regular Solitaire, this has you removing cards that have been dealt in various patterns by tapping on one that's one point above or below the card on top of your deck, which makes it the top card. When you run out of options, you take the next card on the deck and make it the top card you have to match. You win when you've removed all of the cards that have been dealt, and lose if you run out cards in your deck.
Now, obviously, this approach is blasphemous for serious Solitaire players. But if you're not so serious, it can be a lot of fun. Especially since some of the cards in your deck are Joker cards, which are wild, so they can be whatever card you want them to be. Also, if you go on a hot streak, the game will reward you by adding a card to your deck. By solving these puzzles, you'll earn gems that you can use to buy new buildings and other nice things for the aforementioned crab. You even get to choose how these buildings will look...well, within reason (you always pick from three different designs). The only downside, in fact, is that the puzzles can be rather easy, which makes this somewhat redundant if you play for a long period of time. But in short bursts, Undersea Solitaire Tripeaks puts a fun and clever spin on a familiar card game.
