Triple draw where a flush is the minimum to win high — otherwise it's all-or-nothing low.
Button and blinds.
Five cards, three separate discard-and-replace draw rounds.
Small bet after the deal and the first draw, big bet after the last two draws.
Winner takes the whole pot, no split. A flush or better is required to win as high at all; if nobody qualifies, it flips entirely to the best Kansas City-style low hand instead.
