bridges, to avoid misplacing a tile that could be valuable. A player may consider it worthwhile to set up potential hexagons and bridges since this may or may not be to his own benefit; they may even hold the necessary tile to use in his next move. He may feel that placing a tile to which others can be matched is preferable to placing it to form an "impossible" hexagon or bridge.

adjacent tile. A side with a 1 and a 2 will often not match the side the player is attempting to match. If a new tile is being placed such that it would touch two other tiles, then all of the adjacent numbers must match. Where the points of tiles meet the numbers must always be the same; if they are not, someone has been allowed to misplace a tile and the round must be restarted.

When the round ends because no one can place a piece, then the player with the lowest total value hand gains the value in excess of their hand from each other player. For example, if the total value of the remaining tiles in Player B's hand is 15, while Player A's remaining hand sums to 23 and Player
796:
The player who draws the largest "triple" (all three numbers the same on the tile), begins the game by placing that tile. That player scores 10 points plus the total value of the tile. The exception is that if the triple zero tile is used to start, that player earns 40 points. In this case, the only
975:
The game includes only 56 out of 76 possible tiles, omitting those tiles in which the numbers appear in clockwise descending order; i.e., where 0-1-2 is a possible tile, the mirror-image reflection 0-2-1 is not. Consequently, there are many situations in which no tile completes a bridge or hexagon.
936:
Additional rounds are played until one player reaches a total of 400 points. They are not yet the winner, and may not be: this only signals that this is the last round, even if penalties later reduce their total below 400. The winner is the one who has the most points at the end of this last round.
855:
If there are no remaining tiles left to be drawn and a player is unable to place a tile, they lose 10 points. For example, if there are two tiles left, a player without a tile to be placed may draw them (receiving a penalty -10 in total for the two tiles drawn), and if that player still has no tile
851:
If a player cannot place a piece using the tiles in their hand, they must draw a new piece from the remaining pile. Each tile drawn penalizes the player 5 points. Players must continue to draw until a matching tile is found or until they have drawn three tiles. If one of the three can be placed the

Play proceeds clockwise; each player places a tile from their hand that lines up with the already placed tiles. A valid play of a triomino is similar to that of a domino in that the sides contacting each other must have matching numbers; this means the two numbers at the corners must match with the

Tiles are most often made from plastic or resin that approximates the feel of stone or ivory, similar to most modern commercial domino sets. Numbers are recessed into the surface and painted black. Some "deluxe" sets include a raised, brass tack head in the center. This addition to the sets assists
800:
If no triple is held by any player, the player with the highest single tile value plays it and scores its value without the 10 point bonus. Tile values are computed by summing the three numbers. For example, the 2-4-5 tile is worth 2+4+5=11 points. When two or more players hold tiles with the same

At the start of the game, all of the tiles are placed face down and shuffled. Players randomly draw their starting pieces. The specific number depends upon the number of players: a two-player game uses nine pieces per player to start, three or four players use seven pieces, and five or six players
1014:
Much depends on the luck of the draw, but skill plays a part, even if a small one. Players should be aware that they hold a matching tile or tiles and need to decide whether or not to play them or in which order to play them for their best advantage. They should be aware of potential hexagons or

A player who is able to empty their hand and place their last tile receives 25 bonus points, plus the total of all of the remaining tiles in their opponent(s)' hands. This is consistent with the prior ending condition, as the player who emptied their hand has the lowest remaining total value

The yellow line shows where a bridge could be formed with the yellow 0-2-3 tile, but this is no longer possible as the 0-2-3 tile has already been played. Also, the hexagon above the yellow tile cannot be completed, as it would require another tile (0-3-2) which does not

Points are scored based on the numbers on the tile played, with additional bonuses applied when special placements are made. After a tile has been placed legally, each number on the newly placed tile is summed and added to that player's score. (E.g. 5 + 3 + 1 = 9).
82:
Given these restrictions, with the six potential values (0–5) commonly seen, there are 56 unique combinations, and thus the standard triomino set has 56 tiles. Larger sets are possible; for example, including 6 as a possible end number would result in 84 tiles.
882:
914:
Bridges are made by matching one side of the tile and the point opposite. If a bridge is completed or a tile is added to a bridge, that player receives a 40-point bonus in addition to the tile's points, less any penalty if pieces have been drawn.

With only one of the two patterns, there are 21 tiles with one or more of a particular number e.g. there are 21 tiles with one or more "5". There are 6 tiles with any combination of two numbers e.g. there are 6 tiles with one or more 4

The completion of the bridge with the 1-2-5 tile scored 1+2+5+40 = 48 points. The bridge was then augmented with the 1-1-5 tile, which scored 1+1+5+40 = 47 points, as that player was required to match two adjacent

When reading the numbers sequentially clockwise, starting with the lowest value, the numbers are not allowed to decrease. For example, 0-1-2 and 0-2-3 are possible, but 0-2-1 is not allowed.

876:
The completion of the hexagon with the 0-5-5 tile scores 0+5+5 + 50 (bonus) = 60 points in total. Note how all three values on the placed 0-5-5 tile must match the two adjacent tiles.
