It’s solitaire with a twist. One simple rule change makes the game more enjoyable: you can place any card (or stack of cards in order) on an empty spot. Try to move all cards to the foundations. On the playing field you can move cards (or stacks) onto a card 1 higher in value that has an alternate color. Travel to the planets as you make your way through 6 levels of solitaire. Each level is timed so you have to think and act quickly. If you are ready for serious fun, play Space Odyssey Solitaire!
