Big 'O'
 

Big Omaha hi/lo...good for big pots. played exactly the same as its namesake with 5 hole cards. it can only be played with up to 8 players. other variations of omaha include Big river, where the final bet(in limit) may be larger than normal...for example in a 1/2 the river bet could be $8 its interesting and great when you get someone do draw full against your 4 of a kind :) not so good on the other end of that deal.
