ImPLOcean is played with 4 hole cards, but obviously can be played with more. Two turn cards. High only.
Stumpler is also played with 4 cards but can be more. Basically PLO8 but if no qualifying low on the board, the highest ranking hole card with the same suit as the river card wins the "low" half of the pot.
