How do tournament domino rules differ from a kitchen table?

A tournament plays the same game as your kitchen table, but it writes down everything a home game settles by habit or argument. The match has a target and a clock, often 200 points or 40 minutes. Each turn has a time limit. A pass must be said out loud. And a misplay that friends would quietly take back costs points, a yellow card or the match. What a tournament does not have is one universal rulebook. Every rule below belongs to a named event, and the next event may differ.

This article compares four written rulebooks:

FEMUNDO (Federación Mundial de Dominó), whose English competition regulations govern its world championships for individuals, pairs and teams of four.
A club tournament in San Juan, Puerto Rico, run by the Club Náutico de San Juan and the Caparra Country Club.
A tournament at the Universidad de Guadalajara's Lagos campus in Mexico.
A senior games event run by Confa in Colombia in 2026, played individually rather than in pairs.

FEMUNDO is not the only international body; others, such as the Federación Internacional de Dominó, write their own rules. None of them governs the game everywhere.

The match: a target and a clock

At home you play to a score and stop when someone gets there, or when dinner is ready. Tournaments have to finish rounds on schedule, so almost all of them add a clock.

Event	Target	Clock	Tied block
FEMUNDO	200	40 minutes	Nothing scored, rotation continues
San Juan club	200	40 minutes	Nothing scored, previous leader leads again
Lagos, Mexico	100	25 minutes plus two more hands	Nothing scored, the lead rotates
Confa, Colombia	Most hands won	25 minutes	Player who closed the game, or the one to the right of the last player

FEMUNDO adds that a match must have a winner. If time runs out with the scores level, an extra hand is played. In Lagos, points beyond 100 do not count toward the differential used to rank players, so running up the score in the last hand earns nothing.

The clock changes how you play the last few hands. Under a 200-point target, the team ahead when time runs out wins without reaching 200, so with a few minutes left the leader wants a short, safe hand and the trailing team needs a big one. In a pip-scored partnership game, a big hand usually means forcing the opponents to hold heavy tiles, or reaching a block with your own side light. The article on scoring explains where those points come from.

Every turn is timed

FEMUNDO sets three limits for a turn:

5 seconds if you have only one tile you can play, or must pass.
20 seconds if you have a choice.
1 minute if the tile you are about to play blocks the game.

A first offence is a warning; a second costs 40 points. One clause closes a loophole: if you hold the tile that would block the game and think for more than 20 seconds, you must play that tile. You need not play it where it blocks, but you may not think about blocking and then play something else.

Lagos uses the same 20 seconds for a choice and a minute for a closing play. Bogotá's 2024 district community games allow 60 seconds a turn.

This is a real change from many home tables. Pagat.com, John McLeod's rules site, records that in Jamaican partner play, hesitating or playing at once is fair for the table to read. A 5-second limit for forced plays makes that much harder: everyone with one option plays fast, so speed tells you less.

Say "pass" — don't knock

At many tables a pass is a knock on the table or two tiles clicked together. Tournaments tend to want the word.

FEMUNDO: saying PASS is the only valid way to pass. Knocking the board or gesturing breaks the rule: a warning, then 40 points.
Confa: the player says PASO aloud.
San Juan: the player says paso, no tengo or a similar phrase.
Bogotá: striking the table with tiles is forbidden at any point.

A knock can be soft, hard, fast or slow, and a partner can read meaning into each. A spoken word is harder to shade. The article on reading a pass covers what a pass tells everyone once it is made.

Misplays cost points, not a do-over

At home a wrong tile is usually picked up and replaced. In a tournament it is a penalty, and the penalty differs by event.

Offence	FEMUNDO	San Juan club	Lagos
Passing while holding a playable tile	−80 and a yellow card; deliberate: match lost 0–200 and expulsion	Hand ends, offending pair loses it, opponents get 20 extra	−30 off the offender's differential, or the wronged side takes the hand
Placing a tile that does not match	−80 and a yellow card; may be fixed with a warning if nobody has played since	Fix it at once; found later, the hand ends, the offenders lose it and the opponents get 20	May be taken back if the next player has not played; it stays face up
Playing out of turn	−40, the tile is exposed	−20	Not covered
Calling a block that is not one	−40	All unplayed pips go to the opponents	Not covered

Two conventions recur. A touched tile is a played tile: the San Juan rules say so outright, and in Lagos a player who touches or points at a tile must play it. An exposed tile is one the table has seen. Under FEMUNDO it is placed face up to the offender's right and must be played at the first chance, so the offender loses the choice of when to use it.

A false pass is the most serious ordinary mistake for a reason. Every other player's reasoning depends on a pass being true. FEMUNDO lets an opponent claim a false pass at any point in the hand, even after it ends.

Silence, and hands out of sight

The biggest difference is talk. At home, chat is half the game. In a tournament, partners must not be able to signal each other.

FEMUNDO requires both hands under the table, eyes on the table or the tiles, and complete silence. Comments are allowed briefly at the end of a hand, while the tiles are shuffled. Signalling a partner is grounds for a black card, which means losing the match and expulsion. So is "playing an illogical domino to the detriment of himself and his partner", if the referee or the partner can show it.
Lagos wants hands on the knees and eyes on the centre of the table, and it bans eating, drinking, smoking, phones and dark glasses during play.
San Juan takes 20 points for gestures, comments or discussing the hand.

That last FEMUNDO clause is worth noticing. A tile that makes no sense for your own side looks like a message, so the rules treat it as one.

Shuffling, drawing and who leads

Who shuffles and who picks first sound like housekeeping. In a tournament they are rules, because they stop anyone controlling the deal.

FEMUNDO: the first leader is drawn by lot, then the lead rotates. The player to the leader's left shuffles and always draws last. Only the leader may reshuffle, and then draws last instead. You get one or two attempts to set your seven tiles on the rack, with no rearranging after. Seeing more than seven tiles costs 40 points.
Lagos: all four draw a tile and the highest leads, then the lead rotates. The player to the leader's left shuffles.
San Juan: the highest single tile leads the first hand. After that, the player who laid the last tile of the previous hand leads, and the losing pair shuffles.

So two tournaments disagree on the basic question of whether the lead rotates or passes to the winner. The article on choosing your opening tile compares how traditions decide who leads.

Even the first tile's position is written down, and the rulebooks disagree. FEMUNDO lays a mixed tile with the higher number facing the leader's partner. San Juan lays it with the lower number facing the leader.

Scoring a blocked hand

All four events settle a block, and they do not settle it the same way.

FEMUNDO and San Juan: each pair adds its pips. The lighter pair scores the pips in all four hands.
Confa (individual): the player with the fewest pips wins the hand; if pips tie, the fewest tiles.
Ties: see the table above. Nobody scores in three of the four events.

San Juan also states that no bonus is paid for a capicú, a final tile that fits both ends, or for any other play. The article on blocked games covers blocks across home traditions.

What to borrow for your own table

You do not need a referee to use what tournaments learned. Before the first hand, agree on:

Target and time. "200 or 40 minutes, extra hand on a tie" ends the match on time without arguments.
How to pass. Spoken or knocked, but the same for everyone.
Touched tile, played tile. It ends most disputes before they start.
What a false pass costs. Lagos's 30 points or San Juan's lost hand both work. Pick one now rather than after it happens.
Who leads and who shuffles. Rotate it or give it to the winner, but decide.

Leave the silence rule where it fits. A kitchen table without talk is not much of a kitchen table. In partnership play, though, it is worth agreeing what counts as signalling. The guide to partnership play explains why that question matters.
