Strategic Game - like Domino 2.0 - 3-Omino / Triomino / Trimino

‘Triominos’ is a fairly old game title that is also known as “Domino 2.0”. Even some 60 years after its release, the laying game is still very popular among you laying game fans, which is why we are naturally introducing ‘Triominos’ to you.

‘Triominos’ has several names: Tri-Ominos, 3-Omino, Trimino or also Tridomino). This is because it is compared to dominoes, but the tiles have three corners instead of four.

The game could be seen as a kind of collaboration, because although Allan Cowan came up with the rules around the 1960s, the domino game with the triangular tiles was the brainchild of Frank H. Richards, who also patented them in 1885.

You play ‘Triominos’ with 56 triangular tiles (or 76 if you choose a large version). Each tile with the numbers 1 to 5 only appears once. The tile with 3x the number 5 is therefore the highest tile. There is also a tile with the number 0 once and 2 x the number 3. 76 tiles are used in all variants. In the standard version, you only play with the tiles where the numbers are sorted in ascending clockwise order.

Your goal is to get the most points. You can achieve this by placing the stones cleverly.

Starting the game

You choose a ‘referee’ who keeps a score sheet for all players.

All the tiles are placed face down in the centre of the table (called the pot) and shuffled well. You draw your tiles from the pot according to the following procedure:

• 2 players: 9 tiles each
• 3 to 4 players: 7 tiles each
• 5 to 6 players: 6 tiles each

To decide which of you gets to start, each player takes another tile from the pot and shows it to the others. The player with the highest value goes first. You put the stones back in the pot.

The game

Your randomly drawn starting player places a randomly selected tile from the tray face up on the table. You place further tiles in a clockwise direction, whereby the values must match. Each tile must match an edge of a tile that has already been placed. (Example: 2 to 2 and 4 to 4)

If nobody can or wants to place a tile, the currently active player must ‘buy’ a tile. To do this, he draws one from the supply and loses points. You can do this a maximum of 3 times, with each stone taken costing 5 penalty points, which are noted by the referee.
If a tile is still not placed after 3 tiles have been drawn, the player loses 25 penalty points and it is the next player's turn.

However, if he places a stone, the sum of the stone is added to the penalty points. The number of points can therefore be negative or positive.

If no player has or wants to lay a triple stone, the player with the highest total lays the first stone. If two players have the same total, the player with the next highest total places his tile.

Awarding points

• Lay last stone: 25 bonus points
• 40 bonus points: For a bridge (one matching edge and one matching corner)
• The player who places the first stone of the zero stone, i.e. triple-0 (zero), receives: 40 points
• 50 bonus points: Completing a hexagon.
• 60 bonus points: Completion of 2 hexagons at the same time.
• 70 bonus points: Completion of 3 hexagons at the same time

Penalty points

• Buy a new stone: -5 points
• Pass: -25 points

End of the round/game

The player who places the last tile receives a bonus of 25 points and the total number of Triominoes still in the possession of the other players.

The winner is the player with the most points. At the same time, the player who placed the last tile starts the next round.t der Spieler, der den letzten Stein gelegt hat, die nächste Runde ein, die er beginnt.
