Dominoes Rules: Big Six Fives
Every hand comes down to one question: what do the open ends add up to? Here is the whole game, start to finish.
The set and the deal
Big Six Fives is played with a standard double-six set — 28 tiles, every combination of numbers from blank through six. Two, three or four players. With four, it is usually played in partnerships, partners sitting opposite each other.
Tiles are shuffled face down and each player draws a hand. What is left becomes the boneyard, which players draw from when they are stuck. The highest double in anyone's hand opens the game automatically — it goes to the centre of the board and becomes the spinner.
Scoring: the whole game in one rule
After you place a tile, add up every open end on the board. If the total divides evenly by five, you score that total.
That is the entire scoring system. Open ends of 6 and 4 make 10 — score 10. Ends of 3 and 2 make 5 — score 5. Ends of 6 and 3 make 9 — score nothing. You are not scoring the tile you played; you are scoring the state of the board you left behind.
Two things change what an “end” is worth, and between them they cause nearly every argument at a domino table:
- A double at an end counts double. It is laid across the chain and both halves count. A 6-6 at an open end is worth 12, not 6.
- An exposed spinner keeps counting. Until both its sides are covered, the spinner contributes its full face value to the total.
Good players are not counting their own tiles. They are asking what the board will total after the play, whether that total is a multiple of five, and what it hands the next player.
The spinner and the four branches
The first double played is the spinner, and the board grows outward from it in four directions: west, east, north and south.
West and east open first. North and south stay locked until both the west and east sides have a tile on them. Only then does the board open up in all four directions.
The spinner counts while it is exposed. With no more than one of its sides covered, its full face value is part of the open-end total. Cover both sides and it stops counting — it is just another link in the chain from then on. Knowing exactly when that switch flips is the difference between a play that scores and one that does not.
Drawing, passing and blocked hands
Play passes around the table. On your turn you must play a tile that matches an open number if you can.
If you cannot play and the boneyard still has tiles, you draw until you can. If the boneyard is empty, you pass. When every player passes in succession, the hand is blocked and nobody can move.
A blocked hand is not a dead hand. Everyone counts the pips left in their hand and the lowest total takes it. In Fives the winner is paid the losing side's leftover pips rounded to the nearest five — 23 pips left over pays 25. Draw and Block score the raw count. In partnership play the partners' hands are added together first.
This is why shedding heavy tiles early matters even when you are not scoring. A hand full of doubles is a liability the moment the board locks up.
Winning, and the other modes
A game runs until someone reaches the target score. The win is checked the instant it happens, mid-hand — so a scoring play can carry you past the target rather than landing exactly on it. Finishing a game to 150 on 154 is the rule working, not a bug.
Three modes, each with its own targets:
- Fives — the scoring game described above. Played to 100, 150 or 250.
- Draw — no scoring on multiples of five; you win hands and count your opponents' pips. Played to 80, 120 or 200.
- Block — same as Draw, but with no boneyard. Cannot play, you pass. Played to 50, 100 or 150.
Settling the usual arguments
How do you score in All Fives dominoes?
Add up every open end on the board after your tile is placed. If that total is greater than zero and divides evenly by five, you score it. A board showing open ends of 6 and 4 totals 10, so you score 10. If the total is not a multiple of five, the play scores nothing.
Does a double count as one number or two?
A double sitting at an open end counts its full face value — both halves. A 6-6 at the end counts 12, not 6. This is the rule most new players miss, and it is the source of most scoring arguments at the table.
What is the spinner in dominoes?
The spinner is the first double played, and it sits at the centre of the board. While it is exposed — meaning no more than one of its two sides has a tile attached — it counts its full face value toward the open-end total. Once both sides are covered it stops counting and simply becomes part of the chain.
When can you play off the top and bottom of the spinner?
Not straight away. The north and south branches stay locked until both the east and west sides of the spinner have a tile on them. Once both are covered, all four directions are live.
What happens if you cannot play a tile?
If there are tiles left in the boneyard you must draw until you can play. If the boneyard is empty you pass. When every player passes in a row, the hand is blocked.
Who wins a blocked game?
When a hand is blocked, every player totals the pips left in their hand and the lowest total wins. In Fives the winner scores the losing side's remaining pips rounded to the nearest five, so 23 pips left over pays 25. In Draw and Block the raw pip count is scored instead. In partner play the two partners' hands are added together before comparing.
Can you score on the very first play?
Yes. The opening double is the spinner and counts its full face value immediately. Open with 5-5 and the board reads 10, which is a multiple of five, so it scores 10 straight away.
Why did the final score go past the target?
Because the winning play is counted in full. A game to 150 ends the moment a player reaches or passes 150, so a scoring play made at 144 can finish the game at 154. That is correct — the target is a threshold to cross, not an exact number to land on.
