Rules of BigTwo

A deck of cards is distributed to four players. The player with the 3 of diamonds will play first and it has to be included in the first play. Each player can play either 1, 2, 3 or 5 cards. The next player must play something higher than the previous play with the same number of cards from the previous play. If a player decides not to play, he can pass his turn. If all three players pass their turns, the player with the last play will start a new round with anything he chooses.

The ranking of cards in ascending order is 3 < 4 <...< A < 2. The ranking of suits in ascending order is diamond < club < heart < spade. In other words, 2 of spades is the highest card and 3 of diamonds the lowest card. Two or three cards play must be of the same rank. The rank of a pair is determined by the rank, i.e. 2 pair is higher than Ace pair which is higher than King pair. When the ranks are the same, the pair with the spade is higher, e.g. 10 spade, 10 diamond pair is higher than 10 heart, 10 club pair. Similarly, the rank of threes is determined by the rank of the cards, i.e. three 2s is higher than three Aces which is higher than three Kings, etc.

The ranking for five cards play in ascending order is straight < flush < full house < four of a kind < straight flush.

Type	Description	Ranking
Straight	Five cards in a sequence of rank, e.g. 34567, 9TJQK.	Lowest of the all types. Highest straight is TJQKA and lowest is A2345 followed by 23456. Within straight, ranking is first determined by rank then by suit, e.g. 45678 is higher than 34567 & 3456(7 of spades) is higher than 3456(7 of hearts).
Flush	Five cards having the same suit, e.g. 3589J of clubs, 479TK of hearts.	Higher than straight only. Within flush, ranking is determined by the rank of the highest card, e.g. 689TK of diamonds is higher than 79TJQ of spades.
Full House	Consist of a pair and a threes, e.g. 33888, 99KKK	Higher than flush and straight only. Within full house, ranking is determined by the rank of the threes, e.g. 33888 is higher than 99777.
Four of a kind	Consist of four cards of the same rank and any other card, e.g. 44443, 7777K.	Lower than straight flush only. Within four of a kind, ranking is determined by the rank of the four cards, e.g. 3KKKK is higher than A3333.
Straight Flush	Five cards having the same suit and in sequence, e.g 34567 of hearts, TJQKA of spades.	Highest of all types. Ranking of straight in first row also applies here. Within straight flush, ranking is first determined by rank then by suit, e.g. 45678 of diamonds is higher than 34567 of spades & TJQKA of spades is higher than TJQKA of hearts.

After one player gets rid of all his cards, the rank of remaining cards is used to compute each player's score, -1 point for 3, -2 points for 4 and -13 points for 2. If there are 10 cards or more left, the score is doubled. The player who wins will have the total points of three players added to his score. A round is ended and the deck of cards is redealt to the four players to continue play. After 10 rounds of play, your score is calculated and you will have a chance to enter the high scores list. The game is then restarted and the cycle continues.
