It consists of several rounds, each of which has 3 hands. Each round you start with 3 cards, then add 2 for total of 5 and ad two more for a total of 7. An ante is required at the beginning of each round. On the 3 card hand 3′s are wild, 5′s are wild on the 5 card hand, and 7′s are wild on the 7 card hand. Instead of using chips to indicate in or out we usually have the dealer count to 3 allowing folks to push their cards to the middle on or before 3 (this allows for a bit of bluffing). If more than 1 person pushes in then cards are passed around so that only those who have gone in may see them. A mental note is made at to who won, and everyone who went in must pay that person an amount equal to the pot, but the pot only increases at the beginning of a hand. If someone goes in by themselves they earn a ‘leg’ once 4 legs are acquired victory is achieved, and that person wins the pot. We usually stipulate that if a player is about to claim his 4th leg everyone else may have infinite time to challenge.

It’s an entertaining game, but as you say using a large ante such as $1 can bring the pain in a 5-7 player game very quickly.
