Example sentencesExamples
At a game of three card brag at work once, I had a prial of threes (top hand) and my opponent had a prial of aces (next highest).
The best is threes, and the other prials follow in the rank order of the cards: A-A-A, K-K-K, Q-Q-Q, etc. down to 5-5 - 5, 4-4 - 4, 2-2 - 2, three twos being the lowest prial.
Poker players should take care to note that a running flush is beaten by a prial in this game, and that the ‘run’ and ‘flush’ in Brag rank in the opposite order to Poker.
