This variant of Westcliff was invented by our friend Joe Forbes. It is more difficult to win than regular Westcliff, but also more interesting to play. We believe that with careful play, at least two games out of three can be won, and perhaps more.
The top card of the discard pile is available for play onto the tableaus.
Empty tableau piles are important because you can use them to help empty the discard pile. Especially look for ways to preserve empty piles, for example by moving a red 7 from the discard to an empty pile, then creating a new empty pile by moving a black 6 (or build with a black 6 on the bottom) onto the red 7.
If you have only a few cards left in the deck but many in the discard pile, examine the discard pile before moving cards from there to empty tableaus. If you gain no immediate advantage from such a move, and the move uses up an empty tableau, it may be a better bet to fill the empty tableau with cards from another tableau. This violates the first tip about favoring play from the discard pile, but late in the game that tip is less useful than common sense. If you can see that a move from the discard pile won’t be helpful, don’t make it.
