Yahtzee Fives odds
That makes Fives the 5th highest-scoring category of 13 on the sheet, if you spend a whole turn chasing it and nothing else.
What the rerolls buy you
A turn is three rolls: the first, then two rerolls of any dice you don’t keep. Chasing Fives from the first roll alone is worth 4.17; using the full turn is worth 10.53.
| Rolls available | Expected score | Chance of scoring |
|---|---|---|
| First roll only | 4.17 | 59.81% |
| First roll + 1 reroll | 7.64 | 83.85% |
| Full turn (2 rerolls) | 10.53 | 93.51% |
Each row assumes you reroll optimally for this category alone, and nothing else. The two rerolls multiply the first-roll figure by 2.5×. That last column is the same for all six upper categories, and so is that multiplier: a die is equally likely to show a 1 as a 6. The faces differ in what they pay, never in how often they turn up.

How much the first roll decides
Once the first roll lands, you are in one of only 6 genuinely different positions for Fives — every roll inside a tier is worth exactly the same, because the optimal reroll treats them identically.
| Example roll | How often | Turn is now worth |
|---|---|---|
| 0.01% | 25.00 | |
| 0.32% | 21.53 | |
| 3.21% | 18.06 | |
| worst tier | 40.19% | 7.64 |
Top three tiers, then the worst one. The worst tier covers 126 of the 252 distinct opening rolls and lands 40.19% of the time.
Fives and the upper bonus
The upper section pays 35 bonus points at 63, which is exactly three of every face. So Fives has to carry 15 to hold that pace. Chasing it for a whole turn averages 10.53 — short of pace by 4.47, which has to come back from a higher face. This is why the bonus is usually won or lost on fives and sixes.
