A double-12 domino set gives you the tiles for Mexican Train, but the pieces do not tell you which rules to use. Separate the numbered tiles from the starter and train markers, choose one rules reference, and agree on the opening hand before dealing. This guide works through a four-player opening rather than treating every published version as interchangeable.
The set discussed here contains 91 melamine color-dot domino tiles, eight separate colored train markers, one starter with a central black train, and one aluminum case. The tiles measure 50 x 25 x 9 mm. The starter has a cream-colored body with a circular track and a notched outer edge; it is not a smooth round disc.
| Piece | Included quantity | What to distinguish |
|---|---|---|
| Domino tiles | 91 | These are the numbered playing pieces, including blank-ended tiles. |
| Colored train markers | 8 separate pieces | Count them separately from the tiles. |
| Starter | 1 | The central black train belongs to this component; it is not an additional separately supplied ninth player marker. |
| Aluminum case | 1 | It stores the set; it is not an extra playing board. |
Do not confuse the black train model with a numbered domino. Do not assume it is removable, and do not force a tile underneath it. A rulebook's diagram of a different starter does not establish the dimensions or fit of this starter's center.
The worked opening below follows the Tactic Mexican Train rules PDF. For comparison, the University Games printable rules describe a different opening. These are external gameplay references, not the supplied manual or an endorsement of this set. This guide covers setup and preparation, not every exception in either rulebook.
| Decision | Reference used for this example | Other published version |
|---|---|---|
| Four-player hand | 15 tiles per player | 14 tiles per player |
| First turn | One tile, except doubles | A matching sequence may be played |
| Starting the shared train | May begin on the first turn | Not on the first turn |
Pick one complete reference. Do not take the hand size from one column and the first-turn procedure from the other without explicitly agreeing on a house rule. For other player counts, consult the chosen reference's own draw chart rather than extrapolating from four players.
That deal has a useful numerical cross-check: 91 total tiles minus one reserved engine leaves 90. Four hands of 15 use 60, leaving 30 in the draw pile. The count balances as 1 + 60 + 30 = 91. Markers and the starter do not enter this calculation.
If the count is wrong, recount the four hands and the engine before beginning. A marker accidentally included in a tile count will not make up a missing domino. In the alternative 14-tile opening, the same calculation gives 34 remaining tiles: 91 - 1 - (4 x 14) = 34. That is a different chosen deal, not a correction to the 15-tile example.
The engine is the 12-12 domino, not a train-shaped token. Personal trains start with an end matching the engine. The shared Mexican Train is available to everyone. Other players' personal trains become available when marked. If you cannot play, draw once; if still unable, mark your train.
For a visual matching example, 12-5 meets the engine on its 12 end and leaves 5 exposed. A following 5-2 matches that exposed 5 and leaves 2. This is an illustration of matching numbers, not permission to play both tiles on one ordinary turn in the selected version.
Keep the engine visible in the central playing area. The chosen rulebook illustrates an engine inside its own centerpiece, but that illustration is not a fit test for this set. Arrange the starter only where it does not conceal the engine or the ends players need to read.
Before the first turn, locate the sections on doubles, markers, blocked rounds and scoring in the selected PDF. Agree on who will consult it when a question arises. Keeping one reference at the table avoids changing a rule after seeing which player benefits.
Leave space for the shared train, the draw pile and each player's layout. Move cups and other unrelated objects away from that space before dealing. No particular table size is promised: try an empty layout using the actual tiles and the surface you plan to use.
Recheck the 91 tiles and eight separate colored markers before closing the case. Keep the starter distinct from the loose markers so its black train is not counted twice.

No. Double-12 describes the maximum value on a tile end. A complete double-12 set has 91 distinct tiles, using end values from blank through 12.
No. The 91 are domino tiles. This set also includes eight separate colored train markers and one starter with a central black train.
Check with the seller whether printed rules are included before ordering; do not assume they come in the case. The external printable rules linked above are gameplay references, not a promise that a printed copy is supplied with this set.
