Beginner’s guide and rules to Mexican Train Dominoes

These rules follow the most common gameplay. Practice or play against a computer with our iOS, Android, or online Mexican Train Dominoes games.

You will need

Get started

Turn all of your dominoes facedown and shuffle them on the table. Each player draws 1 tile. Whoever has the highest pip-count (dots) goes first. Return the tiles facedown and shuffle.

Each player should draw dominoes as follows:

Stand your dominoes on edge facing you so they’re not visible to your opponents. The remaining dominoes become the “boneyard”. Play moves clockwise.

Your objective is to play all your dominoes and earn the lowest score across 3 rounds.

Placing dominoes and playing doubles

Dominoes must play end-to-end and match.

matching dominoes in a line

Doubles are any tile that show the same number of pips on each side. Playing a double grants you another turn, but must be “closed” by playing another tile on them before you can play anywhere else.

If you can’t close the double, draw 1 tile from the boneyard. If you can close it, do so. If not, play moves to the next player. This process repeats until the double is closed.

Exceptions to doubles:

Start by setting the station number

Player 1 starts the public Mexican Train by placing their highest double in the center to set the station number. For instance, playing a double-6 means the station starts at 6.

If Player 1 does not have a double, play moves clockwise to the next player. If no one has a double, go around again drawing 1 tile from the boneyard until someone does.

Each player’s first move and opening private trains

Once a player opens the public Mexican Train, each player begins their own private train of dominoes by laying a tile that matches the station number. In our example starting at 6, a player must match the 6.

If a player cannot start their train, draw 1 tile from the boneyard. If you still can’t play, place a marker, such as a quarter or other coin, at the end where your tile should be. Play repeats and moves to the next player clockwise.

Starting the Mexican Train

The public Mexican Train begins on an empty line that matches the station number (i.e., 6) in the center or shared between players. It is open to every player and can be started any time after the first round of turns.

Next moves and plays

On each following turn, one domino is played per turn unless a double is played, allowing for two turns.

On your next turn you can:
If you can’t make a move, draw 1 tile from the boneyard. Each player must place a tile on each move or else place a marker indicating their train is open. If the train is already marked, leave it marked.


The game ends when the first player runs out of dominoes and grants them a score of 0. All other plays add up the number of pips (dots) on their remaining dominoes.

Reset and play two more rounds. The person with the lowest score after all three rounds wins.
