This game - in its original incarnation - is quite hard to solve. Although it is harder in the beginning and then it gets easier. To make the game fun to play I added two cheating free cells that you can use. All together this gives you a reasonable chance to solve the game. The game is related to Fortress.

The foundations build ascending from the aces. At each side of the foundation a cascade allows you to build cards regardless of suit and color in descending order.

I added 2 cheating cells to increase your chances to get past the rough start of the game. Emptying one cascade is the key to winning the game.

Hint: Once you have an empty cascade try to keep it clear if possible.

Good Luck!
