G4A: Euchre is the Games4All version of Euchre: a card game that is popular in a large portion of the English speaking world. The main difference between this version and the standard version is that this one has a different set of rules. These are the most important ones:
Each player is dealt 5 cards from a deck consisting of 24 cards: 9, 10, jack, queen, and king. The trump suit has 7 cards, from high to low: Ace, King, Queen, (Jack), Ten, Nine.
After the deal, one of the remaining cards is turned face up. This up-card is used in the first round where each player is allowed to choose a trump suit. If a player chooses the wrong suit, the next player is given a chance.
When all four players reject the trump suit, the up-card is removed from the game and the first player is allowed to choose a new trump suit.
The game ends in a tie if no one has scored. the dealer is allowed to choose one of the remaining three suits as the trump.
Scoring:
The first team to score 10 points wins the match.
If a player has not scored 10 points by the end of the game, he must take a penalty for losing. The exact amount of the penalty is up to the referee.
