From 2 to 4 people can play. The game is most fun when played with 4 people.

Two standard 32 card decks are used. The cards in each suit rank (from high to low) A K Q J 10 9 8 7.

The game consists of a series of hands. The first hand is played with 5 to 10 cards dealt to each player, depending on the selected room stake:

Training Mode: 10 cards

5 Credits room: 5 cards

50 Credits room: 7 cards

500 Credits room: 8 cards

1000 Credits room: 10 cards

The object is for each player to bid the number of tricks he thinks he can take from each hand, then to take exactly that many; no more and no fewer. Initial bids are made sequentially and in each new round the next player in line starts to bid first. After a round is finished the next round will start with one card less. The last round starts once each player has only one card.

In each round a trump suit is randomly selected and displayed in middle of the playing table. The suit of the first card played in each round must be played by all other players following. Players do not have to play a higher card (make the trick) of a given suit but as long as they have a card of the same suit, they have to play a card of this suit. If a player does not have a card of the same suit, the player is free to make the trick with a trump card or to just play any other card. 

Each trick made is awarded with one point. If a player makes exactly the initially called number of tricks, 10 bonus points will be added to the final score.

Final ranking is based on the final number of points. Depending on the number of players, the final points made during the game will be multiplied as follows:

 

2 Players: Winner x2; Loser x1

3 Players: Winner x3; 2^nd x2; Loser x1

4 Players: Winner x4; 2^nd x3; 3^rd x2; Loser x1
