Answer:
You play with two decks shuffled together.
There are eleven rounds. In the first round, each player is dealt three cards, in the second round, four cards, etc., up to thirteen. In each round, the number of cards dealt indicates the card that is wild for the hand. So, in the first round, threes are wild; in the second round, fours; on up to Kings.
After the cards are dealt, the dealer lays the deck in the center and turns up the first card. Play proceeds clockwise. As with other types of rummy, each player (beginning at the dealer's left), draws either from the face-up or face-down pile, then discards one card onto the face-up pile. The goal is to create sets, either of three or more of a kind, or runs (in the same suit) of three or more cards. Aces are always low, and wild cards may be substituted for a card of any value or suit.
When a player has a hand in which all cards fit into some set, with no extra cards, he discards and lays his hand face-up on the table. Each player then has one more turn. After this, the hands are scored as follows: ten penalty points for each face card that does not fit into a set, and penalty points according to the value of each number card that does not fit into a set (one point for each ace, two for each deuce, etc.) A running tally of points is kept through all eleven rounds, and the player with the lowest score is declared the winner.
