House Rules:
5 Sequential Cards high value > 5 Sequential Cards low value > 4 of a kind high value > 4 of a kind low value > 3 of a kind high value> 3 of a kind low value > 2 of a kind high value > 2 of a kind low value
Aces worth more than Kings for pairing, but a sequence of Ace to 5 is a low value sequence
Only Numbers are considered, signs like clubs/spades/hearts/diamond don't count towards pairs.
If you tie then the point pool is split. Everybody starts at 0 and their scores go negative as they play the first round until they win.
Each player ante the entry and is given 5 face down cards of which 3 are revealed immediately. Folding means you lose the entry, staying means you pay an additional amount equal to entry, you can double the bet for this phase (double the entry adding up to triple the initial ante total) and force every player to do the same or fold, and a new card is revealed. This repeats a second time so that all 5 cards are now known to you.
Finally, everyone has their cards revealed to everyone else. Read them and weep.
After Three Rounds the lowest scoring player(s) is eliminated.
If I get a few interested people then I plan to make an interface for it which receives it's cards data from a server. There are no current plans for wagering or prizes, but maybe I'll see what we can do if I get some good feedback.
