A.K.A. Racehorse and Seven Go&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What&amp;#39;s unique:&lt;/strong&gt; If a player plays a double or one of the 5 scoring dominoes (6-4, 5-5, 5-0, 4-1, or 3-2), he may continue to play tiles from his hand.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Object of the game:&lt;/strong&gt; To make the total count of the exposed ends of tiles played equal 5 or a multiple of 5.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Number of players:&lt;/strong&gt; 2 to 4 players. 4 players may play as two teams of 2 players per team.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Number of dominoes drawn:&lt;/strong&gt; 7 tile&amp;#39;s per player.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Set:&lt;/strong&gt; First player must play a double tile or a score file. If the first player is unable to play a double tile or a score tile to set, he 1) passes if there are 4 players, or 2) draws from the boneyard if there are 2 or 3 players.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How to play:&lt;/strong&gt; After the first domino is set, subsequent players must join a tile from their hand with an open end in the line of play. The ends of the two tiles that are joined must have the same number of pips.&lt;br /&gt;
If a player is unable to make a play from his hand, he must draw tiles from the boneyard until he draws a playable tile. If a player is unable to make a play from his hand and there are no tiles left in the boneyard, the player must skip his turn until he is able to make a play.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Scoring:&lt;/strong&gt; 1 point for every multiple of 5. For example: A total of 5 pips on the exposed ends of the tiles in the layout is worth 1 point; 10 pips is worth 2 points; 15 pips, 3 points.&lt;br /&gt;
When a player plays a double or a score tile, including the set domino, he must play again.&lt;br /&gt;
A player may play any matching tile in his hand to the set domino. If he scores or plays a double, he must make another play or 1) pass if there are 4 players, or 2) draw from the boneyard until he draws a playable tile if there are 2 or 3 players.&lt;br /&gt;
In a game of 2 or 3 players, if a player&amp;#39;s last tile is a double or a score tile, he must play it and then draw from the boneyard until he draws another playable tile. In the case of a 2-handed game, he must leave 2 tiles in the boneyard; in a 3-handed game, 1 tile. If he does not hold a playable tile and there are no more available tiles in the boneyard, he must pass. Play continues until 1 player has played the last tile in his hand, and it is not a double tile or a score tile.&lt;br /&gt;
In a game of 4 players, if a player&amp;#39;s last tile is a double or a score tile, he is &amp;quot;washed up.&amp;quot; The other players continue to play until 1 player has played the last tile in his hand, and it is not a double tile or a score tile.&lt;br /&gt;
The game is over when 1 player dominoes or when the game is blocked. The player or team with the lowest number of pips left in his hand (0 in the case of a player who has dominoed) is the winner and receives 1 point for every pip left on the remaining tiles in his opponents&amp;#39; hands.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Variations:&lt;/strong&gt; 1) When there are 2 players, the last two tiles in the boneyard may not be drawn. If there are 3 or 4 players, the last tile in the boneyard may not be drawn. 2) If a player has a playable tile, he must play it.&lt;/p&gt;
