A D3 (three-sided die) generates a random number between 1 and 3. While physical three-sided dice exist, they're uncommon—most players simulate a d3 by rolling a d6 and dividing by 2 (rounding up). This virtual dice roller makes d3 rolls simple and accurate.

How To Use The D3 Roller

  1. Set the number of times you want to roll
  2. Set how many D3 dice to roll per attempt
  3. Click "Roll dice" to generate your results
  4. View individual roll results or the grand total

Simulating D3 With Other Dice

If you don't have a virtual d3 roller, you can simulate one:

  • D6 method: Roll a d6, divide by 2, round up (1-2=1, 3-4=2, 5-6=3)
  • D6 method 2: Roll a d6, 1-2=1, 3-4=2, 5-6=3
