Crossover between Russian Solitaire and Freecell. Move all cards to the 4 foundations. Card on the tableau are build on suit down. You can also move groups. Groups do not have to be in order as long as the top card of a group is of the same suit as the card it will be placed on and is 1 lower in value. Use the free cells to temporarily park cards. Every new level is more difficult and has less free cells.
