Why 7 Comes Up So Often
The 36 possible combinations of two dice are not spread evenly across the sums 2 through 12. Seven has six combinations (1-6, 2-5, 3-4, 4-3, 5-2, 6-1), so it appears 6 out of 36 times — 16.7%. Snake eyes (2) and boxcars (12) have just one combination each, at 2.8% apiece.
2D6 Probability Table
| Sum | Combinations | Probability |
|---|---|---|
| 2 or 12 | 1 each | 2.8% each |
| 3 or 11 | 2 each | 5.6% each |
| 4 or 10 | 3 each | 8.3% each |
| 5 or 9 | 4 each | 11.1% each |
| 6 or 8 | 5 each | 13.9% each |
| 7 | 6 | 16.7% |
Using the Odds at the Table
In Catan, the 6 and 8 number tokens produce resources most often (13.9% each per roll), which is why their dots are red. In Monopoly, the most likely roll out of jail is a 7, and doubles — any matching pair — have a 6-in-36 (16.7%) chance. Knowing the distribution will not change your luck, but it tells you where to build and when to risk a roll.
Frequently Asked Questions
What is the average roll of 2d6?
The expected value is exactly 7. Each d6 averages 3.5, so two dice average 3.5 + 3.5 = 7 over many rolls.
What are the odds of rolling doubles?
There are 6 doubles combinations (1-1 through 6-6) out of 36 total, so doubles come up 1 in 6 times, or 16.7%.
Is 2d6 the same as rolling a 12-sided die?
No. A d12 gives every result from 1 to 12 an equal 8.3% chance. With 2d6 the middle values are far more likely — you cannot roll a 1 at all, and 7 comes up six times as often as 12.
Can I roll 2d6 more than once and keep track?
Yes. Every roll is stored in the history panel with the individual dice and total, keeping your last 10 results visible.
