From the creator of Sage Solitaire, comes a new Solitaire variant that breaks all the rules! 100% of deals are solvable! Like its footwear namesake — Flipflop Solitaire+ is unrestrictive, creating a new game for fans of spider, klondike and other traditional Solitaires. In Flipflop+ you can stack down, up, or even both ways on a single stack! Need to stack an 8 on a 7, or a club on a spade? No problem! - but - Be careful, you can only move a stack of a single suit! It's fun and freeing, but still challenging and captivating. It's Flipflops for your brain. ------WHATS IN THE “BOX”? - Play Flipflop Solitaire+ from 1-5 suits! - Track your best times, least moves, least undos, total wins, total plays, and more - Over 10,000 numbered deals for 1-5 suits - Over a hundred achievements - Change up your backgrounds, card and card back color schemes - Natural ambient binaural background audio - A strong sense of relaxation ------A WORD FROM THE DEVELOPER Flipflop Solitaire+ is sort of a sequel to Sage Solitaire in the sense that it's my second crack at the design problem of making a Solitaire game that feels like it was designed for your phone and not for a table. To be honest this is how I wish everyone approached sequels. Usually a sequel takes the solution to a problem and duplicates it. This is why our expectations of game sequels are often more-of-the-same-but-better. I'd rather see more sequels that brought a renewed level of surprise and novelty, and I'm hoping that's what you find in Flipflop Solitaire+. While Sage was all about trying to capture the feeling of a tight, easy to play, tough to win, zen solitaire game, Flipflop+ is about knots. In a typical Solitaire game, like Klondike, you're taking a knot of cards and untying it into sequences. Then you reverse those sequences into clean ordered stacks. In Flipflop+ you take your knot of cards and tie it into other, hopefully better knots. Then you untie those knots into the final ordered stacks. Having so much control over the way your intermediary knots are constructed led to a lot more depth than I expected. -zach
