I'd go with this line up:
1) BigO-Tahoe aka Tahoe hi/lo (no draw, low or high can be in your hand or on board. 8 qualifier, more pain more gain)((and yes I know others have other names for this...what eva))
2) Archie. - 3 draw rounds, 99+ qualifier hi and 8 qualifier for low, NO BOARD. probably my new favorite degen game. Most dangerous game of them all. And who Is Archie anyway? I am afraid to meet them.
3) Derailment - a twist on the classic Gods Game. Much pain. 3 boards. Lowest river card of the 3 gets that board removed.
4) Draw2maha - kept at draw 2, keeps some donkeys from losing their ass. Highest 5 in hand and highest Omaha hand chop.
5) Doubleboard 5 card - Gods game, nuff said.
6) Dramaha49 - Torn between this and dramaha Low. a coin flip. Omaha hIgh hand and highest pips in hole hand. four tens and a 9 is the nut high. hence 49
6+1) Scarney. - Icelandic rules. Lose all your cards. GTFO ! And normal Scary too. LOL 6 in hand.
I put as 6+1 because it doesn't have to get called. can be thrown in anywhere. Shouldn't be played after 1am when everyones drunk.
