Muggins

A good game of the point-type of domino game for two to four players, using a Double-Six domino-set, and a score-sheet.

Play:

The dominoes are shuffled facedown, then each player draws seven tiles that only they can look at.  Any remaining tiles are used as the boneyard and may be drawn upon by players during the course of play.

The lead player sets down the first domino (which may be any tile he wishes) and then players in turn lay tiles onto the open ends of the domino layout with same-number adjacent to same-number.

Players score points every time they play a tile onto the layout and the pips on the open ends total a multiple 5.  For example 5 points if the ends total 5; 10 points if the ends total 10; 15 points if the ends total 15; and so on.  Players must announce their scoring points to claim them and record it on the score-sheet.  Should a player fail to claim a scoring play, any other player may claim the points by announcing "muggins!".

Once a player has dominoed by setting their last tile, or the game is blocked with no player able to set a tile, the round is over and the player who dominoed or has the lowest total of pips left in their hand, is the winner of that round.  The winner of a round then scores the total number of pips on all the other players' dominoes rounded up or down to the nearest multiple of 5.

A number of rounds are played and the first player to score a set total (say 100, 200, or 250 points), wins the game.  

Variations:

When playing as partners, the pips on the winning player's partner's dominoes are subtracted from their total score.  Partners' scores are totalled together to form a combined total score.

Sometimes played with the last two tiles in the boneyard not drawn when players are unable to make a play.
