D3 Dice Roller
Roll a three-sided result online — generated as a true 1-to-3 value, the same outcome tabletop players get by halving a d6 roll.
Roll history
Your rolls will appear here.
Most dice sets don't include a physical three-sided die, so tabletop players usually roll a d6 and divide by two, rounding up, to get a 1-to-3 result (1–2 becomes 1, 3–4 becomes 2, 5–6 becomes 3). This d3 dice roller skips that conversion and returns a direct, evenly weighted 1-to-3 result.
How a D3 Roll Works
Each of the three outcomes — 1, 2 or 3 — has an equal chance, matching the odds you would get from the traditional halved-d6 method, just without doing the division yourself.
When Games Call for a D3
Some D&D spells and monster abilities specify d3 damage or effects directly, and various board and war games use three-way random outcomes for minor decisions.
Frequently asked questions
How is a d3 normally rolled without a physical die?
Players typically roll a standard d6 and halve the result, rounding up, so 1–2 counts as 1, 3–4 as 2, and 5–6 as 3.
Is this roller's d3 result fair?
Yes, each of the three outcomes has an equal 1-in-3 chance, generated directly rather than derived from a d6.
Is this free?
Yes, completely free to use.
