Short Table, Full Table: How Table Size Changes Your Mark

The dice do not care how many people are playing. Fifteen dice average 52.5 at a table of two and at a table of nine. What changes is what your Mark has to do. Against one opponent you only have to be on the right side of their number. At a full table you have to find a gap nobody else is standing in.

Two players: above or below

With one opponent, the hand has only two results. Either the total reaches the higher Mark and the higher Mark wins, or it does not and the lower Mark wins. That is true even when both players go over, because then the lowest Mark takes the pot.

So the exact number matters much less than you would think. Suppose your opponent has picked 53.

Every Mark below 53 wins exactly the same hands: the ones where the total is 52 or less. A 45 and a 52 are the same pick. Going above is different, because now you need the total to reach you, and each point higher costs you hands.

Now suppose the opponent picked 50. Any Mark below them wins 32.7% of the time. A 51, one point above, wins 61.8%. A 53 wins 50.0%.

That gives a simple rule for two players. If you think your opponent is at 52 or lower, sit just above them. If you think they are at 53 or higher, go anywhere below. You are not guessing the dice. You are guessing one person.

Nine players: you only win your own slice

At a full table your Mark wins when the total lands on it or in the space between it and the next Mark up. The lowest Mark also collects when everyone goes over. The more players there are, the thinner those slices get.

Here is an example table of nine. The Marks are made up for illustration, with most players near the average and a few further out.

With nine players an even share would be about 11% each. The four players in the middle each get about half of that. They picked the most likely totals, and each of them can only win on one exact number. The players at the edges picked less likely totals and win more often, because nobody is sharing their space.

This does not mean 45 is a great Mark. It means that at this table nobody else went low. Add a player on 47 and the 45 drops to 18.4%.

The winner gets closer to the total

There is a second effect of a full table. With more Marks in play, somebody is nearly always right next to the total. In the nine-player example the winning Mark is within one point of the total in 68.6% of hands. With only the 48 and the 56 at the table, that happens in just 20.0%.

That changes how to read a made Mark, one the total has already reached. Being five points under the total wins often against one opponent. Against eight it rarely does, because someone is usually sitting in those five points.

A full table does not stay full

Players fold on every betting round. A hand that starts with nine often reaches the last roll with two or three. Your Mark was picked for a full table, but the showdown may be a short one, and the two-player rule takes over: what matters then is whether you are above or below the players who are left.

This is worth remembering when you hold a number in the crowded middle. Every player who folds widens your slice.

What to do with this

• Two or three players: think about the people, not the average. Decide whether to be over or under them. Tucking in one point above a cautious player is strong.
• A full table: watch the Marks shown at each showdown and look for the gap. If the table keeps showing 51, 52 and 53, the room is at 49 or at 55.
• Any size: a tie splits the pot, so the most popular number pays the least.

The chance of the total reaching every Mark is in the strategy guide, and The Coin-Flip Number looks at 53 on its own.
