Gin Rummy is a two player card game created in 1909 by Elwood T. Baker and his son C. Graham Baker. This delightflull game is played with the Anglo-American deck.
The GOAL is improving your hand by generating melds and eventually eliminating your deadwood.
There are 2 types of meld : set and run.
A set is 3 or 4 cards with the same rank.
i.e. {[H_7],[S_7],[D_7],[C_7]} or {[S_Q],[D_Q],[C_Q]}
A run is leastways 3 of ´suit´ cards in a numerical sequence.
i.e. {[S_A],[S_2],[S_3]} or {[H_10],[H_J],[H_Q],[H_K]}
Deadwood stands for a group of cards which do not belong to any set or run meld.
Deadwood Count is exactly the sum of the each deadwood cards point value.
Cards value in point of deadwood
[A]ces : 1 point.
Face cards{[J],[Q],[K]} : 10 points.
Others : written.
In order to finish a round, the player have to make a Gin or a Big Gin or at least a Knock.
If deadwood count is less than or equal to 10 points, the player can Knock.
If the all 11 cards in a hand are melt, in other
words, when deadwood counts is equal to zero, the player can make a Big Gin. (+50 points)
If the 10 cards in a hand are melt and only 1 card remains in deadwood, the player can make a Gin. (+25 points)
The difference of opponents and the players deadwood counts is evaluated as the score when a knock is happened.
If the knockers deadwood count is equal or greater than the opponents, undercut is occurred (+20 points)
The player ,who reaches to 100 points before the opponent, wins the game.
Good Luck.
