Big O

Big O is also known as Five Card Omaha High/Low Eight-or-Better.

Forced Money

The game is played with a button and blinds.

Dealing Procedure

Each player is dealt five cards face down, followed by a round of betting at the small bet limit.

Three community cards are placed face up. This is followed by a round of betting at the small bet limit.

One additional community card is placed face up. This is followed by a round of betting at the big bet limit.

One additional community card is placed face up. This is followed by a round of betting at the big bet limit. This is followed by a showdown.

Evaluating the Showdown

The best high hand and best California low hand of at least eight low or better splits the pot. Hands are made using exactly two cards from each player’s hand and exactly three cards from the board. Note: If there are not three unpaired cards eight or lower on the board, no low hand is possible. If no qualifying low hand is made, the high hand scoops the pot.

Notes

Big O is usually played as a pot-limit game, but was played as a limit game for the Big OE mix at BARGE 2021.
