Key Facts

  • Standard polyhedral dice: D4, D6, D8, D10, D12, D20, D100
  • Dice notation: NdX+M (N dice with X sides plus modifier)
  • D20: main die for D&D attacks, saves, and skill checks
  • Advantage: roll 2d20, take higher; Disadvantage: take lower
  • Custom dice support up to D1000
  • Roll expressions like "4d6 drop lowest" for ability scores
  • Keep/drop rules: 4d6kh3 (keep highest 3), 4d6dl1 (drop lowest 1)
  • 3D animated dice with realistic physics simulation

Frequently Asked Questions

Dice notation follows XdY+Z format: X = number of dice, d = dice, Y = number of sides, Z = modifier. 2d6+3 means roll 2 six-sided dice and add 3 to the total. The modifier can be positive (+) or negative (-).

XdY+Z: X dice, Y sides, +Z modifier. 2d6+3 = roll 2 d6s, add 3.

Advantage means rolling 2d20 and taking the higher result. Disadvantage means rolling 2d20 and taking the lower result. They cancel each other out if both apply. Advantage adds roughly +3.5 to your average roll.

Roll 2d20: advantage takes higher, disadvantage takes lower. Worth about +/-3.5.

The standard method is 4d6 drop lowest: roll 4 six-sided dice, remove the lowest die, sum the remaining three. Repeat 6 times for all abilities. Range is 3-18, average is about 12.2. Use "4d6kh3" notation.

4d6 drop lowest (4d6kh3), six times. Range 3-18, average ~12.2.

kh = keep highest, kl = keep lowest, dh = drop highest, dl = drop lowest. The number after indicates how many to keep/drop. 4d6kh3 means roll 4d6, keep the 3 highest. 2d20kl1 is disadvantage.

kh=keep highest, kl=keep lowest, dh=drop highest, dl=drop lowest.

Our dice roller uses the Web Crypto API which provides cryptographically secure pseudorandom numbers. This is statistically indistinguishable from true randomness and suitable for any gaming purpose.

Yes, uses cryptographic randomness - fair for all gaming.
