The most a 20th-level rogue can roll is 60, or 120 on a critical hit.
When it applies
Once per turn, when you hit with a finesse or ranged weapon, you add the Sneak Attack dice if either:
- you have advantage on the attack roll, or
- another enemy of the target is within 5 feet of it, isn't incapacitated, and you don't have disadvantage.
Once per turn, not once per round: a Sneak Attack on an opportunity attack, during someone else's turn, is fair game.
Finesse weapons in the SRD: dagger, dart, rapier, scimitar, shortsword, whip. Any ranged weapon works too, such as a shortbow, light crossbow or hand crossbow.
Landing it every turn
A rogue gets Sneak Attack once, but has two chances to hit with two light weapons: the attack, then the off-hand bonus attack. If the first misses, the second can still carry the dice. Cunning Action spends the bonus action instead, so it is one or the other. Chance to land Sneak Attack with one attack or two:
| To hit | One | Two |
|---|---|---|
| 50% | 50% | 75% |
| 55% | 55% | 79.8% |
| 60% | 60% | 84% |
| 65% | 65% | 87.8% |
| 70% | 70% | 91% |
Advantage does much the same for a single attack. Needing a 10, advantage lifts the hit chance from 55% to 79.8%, and the chance of a critical hit from 5% to 9.75%. Hiding with Cunning Action is the usual way to get it. More on the advantage page.
Critical hits
A critical hit doubles every damage die in the attack, Sneak Attack included. A 5th-level rogue's crit with a rapier is 2d8 + 6d6 plus the modifier, 33 on average with a +3. Advantage makes both the hit and the crit more likely. Work out any other roll on the dice calculator.

Questions
How many Sneak Attack dice does a rogue get?
One d6 at 1st level, and one more at every odd level after: 2d6 at 3rd, 3d6 at 5th, up to 10d6 at 19th. Half the rogue's level, rounded up.
Can you Sneak Attack more than once per turn?
No, once per turn. But it is once per turn, not per round, so a hit on an opportunity attack during another creature's turn can add Sneak Attack again.
Do you need advantage to Sneak Attack?
No. An ally (any other enemy of the target) within 5 feet of the target is enough, as long as that ally isn't incapacitated and you don't have disadvantage.
Does Sneak Attack double on a critical hit?
Yes. A critical hit doubles all the attack's damage dice, Sneak Attack dice included. A 19th-level rogue's crit rolls 20d6 of Sneak Attack, 70 on average.
Does Sneak Attack work with spells or unarmed strikes?
No. It needs an attack with a finesse or ranged weapon. Spell attacks and unarmed strikes don't qualify. A thrown dagger or dart does.
Is this Sneak Attack roller fair?
Yes. Each d6 comes from your browser's cryptographic random number generator with no bias towards any face, so every die is an even 1 to 6.
