How doubles work
Doubles are the tiles with the same number on both ends. They are the part of Mexican Train people argue about most, so here is how it works in plain words.
The basic rule
A double has to be covered. When you play one, you play again right away and put a matching tile on it. A 6|6 needs any tile with a 6.
When you can't cover it
- Draw one tile. If it fits on the double, play it.
- If not, your turn is over and your train opens.
- The next player must cover the double before playing anywhere else.
Why doubles matter
A double is a free extra turn – if you can cover it. If you can't, it can trap you and open your train. So before you play a double, check that you hold a tile to put on it.

Questions
Do I have to cover my own double?
You should try. Right after playing a double you get to play again, and that tile has to go on the double. If you can't, draw one. If it still doesn't fit, your turn ends and your train opens.
What if nobody can cover a double?
Every player must try in turn – drawing if needed. Nothing else can be played until someone covers it.
Can I end the round on a double?
In our game, yes – if a double is your last tile, you go out. Some families say a double can never be your last tile. Agree before you start.
