D6 Roller
Roll a virtual d6 — a cube, the familiar die of board games, usually with pips whose opposite faces add to 7. Every face lands with an equal 1-in-6 probability and an average roll of 3.5, generated with cryptographic randomness in your browser. The d6 is the die almost everyone pictures: a cube with pip faces arranged so opposite sides sum to seven (1–6, 2–5, 3–4). Dice of bone and ivory with exactly this arrangement survive from ancient Egypt and the Indus Valley, making the d6 the oldest die design still in mass production.

Worked example
D6 Roller: Sides per die = 6; Dice count = 1. Roll a virtual d6 — a cube, the familiar die of board games, usually with pips whose opposite faces add to 7. Every face lands with an equal 1-in-6 probability and an average roll of 3.5, generated with cryptographic randomness in your browser. The d6 is the die almost everyone pictures: a cube with pip faces arranged so opposite sides sum to seven (1–6, 2–5, 3–4). Dice of bone and ivory with exactly this arrangement survive from ancient Egypt and the Indus Valley, making the d6 the oldest die design still in mass production.

Results explained
- Total
- The sum of the independent d6 rolls shown, each a uniform integer from 1 to 6.
- Rolls
- The individual die results in the order rolled.
- Expected total (average over many rolls)
- Dice count × 3.5, the theoretical average for a d6.
- Chance of the maximum total
- The probability that every die in the roll shows 6 at once: (1/6)^count.
Frequently asked questions
Craps is built on pairs of d6s (which is why 7, the most likely total, drives the game), and Backgammon, Yahtzee, Monopoly movement, Farkle and nearly every classic board game run on d6s. Warhammer and most miniatures games also use d6s almost exclusively.
(6 + 1) ÷ 2 = 3.5. Every face from 1 to 6 is equally likely, so the long-run average sits exactly halfway between the minimum and maximum.
Exactly 1 in 6, or 16.67%, on a single die. With two dice both showing 6 the chance drops to 1 in 36 (2.778%).
Yes. Rolls come from the Web Crypto API with rejection sampling, so no face is favoured by modulo bias, and nothing is weighted, seeded from the clock or influenced by previous rolls.
Two d6s do not behave like one d12: totals cluster around 7 (a 1-in-6 chance) while 2 and 12 each occur only 1 time in 36 — that bell-shaped curve is why game designers love paired d6s.
Yes — raise the dice count (gamers write that as 2d6, 3d6 and so on). Totals then follow a bell curve centred on 3.5 per die: extremes get rarer as you add dice, which is why multi-dice rolls feel more predictable than a single big die.
