Clear rules, better games
Tournament Rules vs House Rules
A familiar rule at one table may be optional at another. Competitive regulations provide one documented baseline; house rules still need an explicit agreement.

Direct answer
Are house rules wrong?
No. A house rule is valid when everyone agrees to it before play. The mistake is presenting a local custom as universal or changing it after a disputed hand.
What to remember
→
International competition rules govern a specific four-player pairs format, not every domino tradition.
→
The FID format uses 28 Fichas, seven per player, and scores all unplayed pips after a hand.
→
Agree on opener, target, blocked hands, bonuses, and penalties before the first shuffle.
In this guide
There is no single rulebook for every game called dominoes. Published rule collections document many distinct games and variations, while the International Domino Federation maintains regulations for its own competitive format.
01.
What the international competition baseline actually says
The International Domino Federation regulations describe four players arranged as two opposing pairs. The 28 Fichas are shuffled face down, and each player selects seven.
When one player empties their hand, the winning pair receives the total pips left across all unplayed Fichas. When the hand blocks, the pair with fewer unplayed pips wins and the same total is counted; an equal pip count makes that blocked hand a draw. Competition authorities set the match target or time limit.
02.
What makes a rule a house rule
A house rule is a local choice that is not automatically binding outside that group. It may concern who opens, a bonus, a shutout, the score target, or how a tied tranque is handled.
Published domino references catalog many different games and variations. That diversity is why phrases such as ‘official domino rules’ need context: official for which organization, competition, or named game?
03.
The five-question pre-game agreement
A short rules check prevents most disputes without draining the table's energy. State the decisions plainly and keep the same settings for the whole match.
—
Who opens the first hand, and who opens after that?
—
What score or time limit ends the match?
—
How is a blocked hand scored, including an equal pip count?
—
Do capicua, pollona, or other named finishes earn a bonus?
—
Which mistakes carry a warning, replay, point penalty, or loss of hand?
Frequently asked questions
Do international rules apply automatically at a family table?
No. They provide a documented competition format. A family or community table can use different agreed rules.
What should happen if nobody agreed on a bonus?
Pause and choose a rule for future hands. Avoid inventing a retroactive bonus after the outcome is known.
