Omaha Hi/Lo where a dice roll — not a fixed 8 — sets the low-hand qualifier.
Button and blinds.
Four hole cards, a flop, then dice determine the low qualifier before the turn and river.
Small bet preflop and on the flop, big bet on the turn and river.
Pot splits high/low, but what counts as a qualifying low changes hand to hand based on the roll — sometimes tighter than 8-or-better, sometimes looser, sometimes no low is possible at all.
