– Participants are expected to keep their own time, in the event of a tie a sudden death elimination will consist of teams playing to one mark.  

A dealer is selected shuffling the dominoes face down on the table. Each player draws and domnio, the player drawing the highest number of dots is the first dealer. The dealer then reshuffles all dominoes face down, players draw 7 dominoes to begin the hand, following the hand the deal moves clockwise around the table. 

The player sitting to the left of the dealer is the first bidder. The bid moves clockwise around the table until every player has the opportunity to bid by raising a previous bid or passing. Each player has only one chance to bid before play of the hand begins. Bidding begins at 30 and moves upward to 42 (One Mark). “Mark” bidding may not start at 126 (Three Marks) or higher. After a 42 or 84 bid, subsequent bids must be made in one mark increments. All Mark level bids must be stacked

To maintain pace of play, no “Pass Out” hands will be allowed, if the first 3 players pass, the 4th player must bid a minimum of 30. 

The highest bidder announces trumps and starts the game by playing the first domino. No trumps “follow me” will be allowed. Players must follow the suit led by the first player of each trick. If trumps are not led, the highest suit on the domino led establishes the suit a player must follow. If it is not possible to follow suit, then a player may throw a trump, a count domino or an “off: 

Trumps cannot be played if it is possible to follow suit with other dominoes. The highest trump or highest domino takes the trick. When doubles are trumps the same trump rules apply: the lead of a double requires play of a double, when possible. 

Bidding NELLO is not permitted. 

Helpful Terms 

There are 7 dominoes in each suit, six with the number of dots on one end being the same and one with the number of dots on both ends the same. The latter is called a double. Doubles can also be classed as a suit in the same order of importance: 6-6, 5-5, 4-4, 3-3, 2-2, 1-1, 0-0. There are a total of 8 different suits: Blanks, 1’s, 2’s, 3’s, 4’s, 5’s, 6’s and doubles. 

The highest bidder’s suit becomes the main trumps for the duration of one hand. Trumps are higher than any domnio and will take tricks including doubles of other suits. 

Any domino which has not been played and is the highest in its suit after the double and other higher ones have been played.

There are 5 count dominoes in double six sets of dominoes, 5-5 and 6-4 which count 10 points, and 0-5, 3-2, 1-4 which count 5 points.

A trick cosists of 4 dominoes, each player playing 1 domino in clockwise rotation around the table. There are 7 tricks in each hand.

Each trick counts 1 point plus the values of “count” dominoes in each trick.


– All games will be scored one game to seven marks (ALL) 

– There are 7 tricks that make a total of 42 points. To determine if a bid is made or not, add the number of points in the bidder’s tricks. If they do not total the amount bid or more the player is “set” tricks with count dominoes in them still count 1 points for the trick.
