Roll d6 dice online with presets for 1d6–8d6, modifiers, keep highest/lowest, reroll 1s, and full face distribution charts. Perfect for board games and RPGs.
The six-sided die is the most recognizable die in the world. From Yahtzee to Monopoly, RISK to D&D ability scores, the d6 is everywhere. Each face shows 1 through 6 pips, with each result equally likely at 1/6 or roughly 16.67%. The d6's expected value of 3.5 per die makes probability calculations intuitive and accessible.
Our 6-Sided Dice Roller lets you throw 1 to 100 d6s at once with optional modifiers, keep-best or keep-worst mechanics, and the classic "reroll 1s" house rule. Presets cover the most common scenarios: 1d6 for basic checks, 2d6 for board games, 3d6 for old-school ability scores, 4d6-drop-lowest for modern stat generation, and 6d6+ for spell damage.
Every roll is recorded with a visual frequency chart using classic die-face symbols. Compare your luck against theoretical expectations and run multiple rolls to see the central limit theorem in action. Check the example with realistic values before reporting.
D6 dice are the most common physical dice and form the backbone of hundreds of games. But when you need multiple rolls quickly, physical dice slow you down. Our roller handles massive pools instantly and tracks every result. The face distribution chart validates fairness and helps teach probability concepts.
For D&D players, the built-in keep-highest and reroll-1s options simplify stat generation — no more fumbling with pencils and scratch paper. Just set 4d6 keep 3, reroll 1s, and click six times.
Expected value per d6: E = (1+2+3+4+5+6)/6 = 3.5. Variance: Var = 35/12 ≈ 2.917. Standard deviation: σ ≈ 1.708. For Nd6: E = 3.5N, Var = 2.917N.
Result: 4d6 keep highest 3 → [2, 3, 5, 6] keep [3, 5, 6] → Total = 14
This is D&D's standard method for rolling ability scores. Roll 4d6, drop the lowest, and sum the remaining three. The result 14 is above the 12.24 average for this method.
The six-sided die has been used for gaming since at least 3000 BCE, with early examples found in Ur, Mesopotamia. Its cubic shape makes it easy to manufacture and read, which explains its universal adoption across cultures and millennia. Today, a set of d6 can be found in nearly every household.
The gold standard for D&D character creation is "4d6 drop lowest." This method produces a distribution centered around 12.24 with a standard deviation of about 2.85, generating heroic but still variable scores. Alternative methods include: 3d6 straight (mean 10.5, old-school feel), 2d6+6 (mean 13, floor of 8), and point-buy (no randomness). The reroll-1s variant further pushes averages upward.
Many modern board games use d6 pools where the number of dice represents resources, troops, or abilities. In RISK, attackers roll up to 3d6 and defenders up to 2d6 — by comparing sorted pairs, the system creates battles where more dice generally wins but upsets are possible. Understanding d6 pool probability helps develop optimal strategies.
Exactly 1/6 or approximately 16.67%. Over many rolls, each face should appear with nearly equal frequency.
Roll four d6 dice, remove the single lowest result, and sum the remaining three. This averages about 12.24 (versus 10.5 for straight 3d6), giving heroic ability scores.
For N dice, the probability of all sixes is (1/6)^N. For 2d6: 1/36 ≈ 2.78%. For 3d6: 1/216 ≈ 0.46%. For 6d6: 1/46656 ≈ 0.002%.
2d6 ranges from 2-12 with average 7 and a bell curve favoring 7. 1d12 ranges from 1-12 with average 6.5 and flat distribution. 2d6 is more predictable.
Box cars is rolling double sixes (12) with 2d6, which has a 1/36 ≈ 2.78% chance. In craps, it's a losing roll on the come-out.
8d6 at base level (8th-level spell slot). Average damage: 8 × 3.5 = 28. With a Dexterity save for half, effective average is 21.
