Five hole cards, keep as many as you want, then a normal Omaha-style hi/lo board.
Button and blinds.
Five hole cards, discard down to anywhere from one to five kept, then a flop, turn, and river.
Small bet after the deal and the flop, big bet on the turn and river.
Pot splits high/low (8-qualifier). Because you choose how many hole cards to keep, a low hand stays reachable no matter what the board looks like — unlike standard Omaha Hi/Lo, where a bad board can kill the low side outright.
