Reading the First Roll: Just Add 35

Your Mark is locked before a single die is rolled. From then on, the only thing you control is how you bet. The first roll is where that starts to matter, and there is a one-second trick for reading it: take the first five dice and add 35.

Why 35

A die averages 3.5. After the first roll, ten dice are still to come, and ten dice average 35. So whatever the first five add up to, your best estimate of the final total is that number plus 35.

• First roll of 17 or 18: on course for 52 or 53, right on the long-run average.
• First roll of 24: on course for 59.
• First roll of 11: on course for 46.

It is an estimate, not a promise. The ten dice still to come land between 30 and 40 about 69% of the time, so the finish can drift five points either side. But the centre of the target has moved, and it will not move back.

How much one roll changes things

This table shows the chance that the final total reaches three different Marks: before any dice, and after a cold, an average and a hot first roll.

Look at the Mark of 58. Before the dice it comes in less than one hand in four. After a first roll of 24 it is better than even money. After an 11 it is all but finished, with a 1.6% chance. One roll took the same number from a long shot to a favourite, or to nearly nothing.

The cautious Mark of 48 swings too. After a hot roll it is almost certain to be alive, but that is the moment it is least likely to win, because the higher Marks at the table have come alive as well.

After a hot roll

A first roll of 22 or more shows up about one hand in seven. When it does:

• High Marks become the strong hands. If you picked in the mid to high 50s, this is your roll. Bet it.
• Low Marks are safe but exposed. A 46 or 48 will almost certainly be under the total, and so will everyone else's number. You are alive and probably behind. Calling small bets is fine. Building a big pot is not.

After a cold roll

A first roll of 13 or less is just as common, about one hand in seven.

• Low Marks take over. With the total heading for the mid 40s, a Mark of 46 or 47 may be the only one that is not over.
• High Marks should slow down. If you need the remaining ten dice to beat their average by eight or ten points, you are hoping, not betting.
• Remember the last rule. If every player left goes over, the lowest Mark wins. After a cold roll, a middling Mark such as 50 can still take the pot that way, as long as everyone else still in picked higher.

After an average roll

More than half of all first rolls land between 15 and 20. Then nothing much has changed: the table above shows a 17 leaves every Mark close to where it started. Do not read drama into an ordinary roll. Check if you can, call small bets, and wait for the second roll to tell you more.

Watch who reacts

Everyone at the table sees the same dice and can do the same sum. A player who suddenly starts betting after a 24 has probably picked high. One who stays relaxed after an 11 has probably picked low. You cannot see their Mark, but the first roll often tells you which side of yours it is on.
