Gongor Whist

Gongor Whist is a solitaire trick-taking game in which you try to win tricks against a dummy hand. The trump is randomly determined by flipping over an Ace, but with every trick you have the option of randomly determining a new trump.

Each pass through the deck is two hands; each hand uses about half the cards.

The goal is to successfully make all the possible bids without repeating any of them.
