The only thing more depressing than playing Solitaire by yourself is not playing it on a computer. Unless the deck of cards you're using features levels from four classic Super Mario games.
This $US9 deck is officially licensed by Nintendo and each suit features level artwork from a different game in the Mario series. Spades are Super Mario Bros., hearts are Super Mario Bros. 3, clubs are Super Mario World, and diamonds are New Super Mario Bros. U. Hopefully the Joker is Super Mario Sunshine, unless there's a worse Mario game we're forgetting. [Amazon Japan via NewLaunches]
