10 Sided Dice Roller (D10)

Your details

How many D10 dice to roll at once (1 to 15).
A flat number added to (or subtracted from) the total. Common in RPGs for ability bonuses.
Change this number to trigger a new roll. In a real session you would click Roll again; here each new seed produces a fresh random result.
Standard D10 faces show 1-10. The percentile tens-die shows 0-9 (used alongside a units die to produce 01-100).

Rolled 12 on 2D10

  • You rolled 2 D10s and got a dice sum of 12.
  • The expected (average) total for this setup is 11.0, so your roll is above average.
  • There is a 45.0% chance of rolling at least this sum on any given roll.
  • The exact probability of rolling this sum is 9.00%.

Next stepTwo D10s can be used as a percentile (D100) roll: one die represents the tens digit and the other the units digit, giving outcomes from 01 to 100.
