Extremely solid version of spider solitaire with a bit more than you'd expect. The optional-to-use power ups can salvage an otherwise dead game to preserve a streak, soften frustration, especially if you don't play with undos. The backgrounds and cardbacks are pleasant and non-obtrusive, though it'd be perfect if I could use my own images. A lot of consideration with controls and options with support for keyboard, controller, and turning off auto-placement double clicks. It's also neat that you can watch or replay the rounds of others on the leader boards. The price feels like a steal even when there are innumerable but inferior free versions you could play instead.
