Hold'em with the 2s through 5s removed (36 cards).
Hand order is straight flush > quads > flush > full house > straight > trips, and the lowest straight is A-6-7-8-9. Example: with 36 cards a flush draw has 5 outs, and outs are ×3 (next card) / ×6 (to the river). The common format has no blinds: everyone antes 1 and the button antes 2, but some tables rank trips above a straight or use normal blinds, so check before you sit.
