How do you roll dice online?
Select your dice type (D4, D6, D8, D10, D12, D20, or D100), choose how many dice to roll, and click "Roll" or press the Space bar. The dice roller uses cryptographically secure random numbers (crypto.getRandomValues) for fair, unbiased results — more random than physical dice.
What dice do you need for Dungeons & Dragons?
A standard D&D dice set includes 7 dice: D4 (damage for daggers), D6 (ability scores, fireballs), D8 (longsword damage), D10 (some weapon damage), D12 (greataxe damage), D20 (attack rolls, saving throws, ability checks), and D100/percentile (random tables). The D20 is the most frequently used die in D&D.
Is an online dice roller truly random?
This dice roller uses the Web Crypto API (crypto.getRandomValues), which generates cryptographically secure pseudo-random numbers. This is significantly more random and unbiased than physical dice, which can have manufacturing imperfections that cause certain numbers to appear more frequently. Studies have confirmed that even dice from the same manufacturer can vary significantly in fairness.
What is a D20 dice used for?
The D20 (20-sided die) is the most iconic die in tabletop RPGs like Dungeons & Dragons. It is used for attack rolls, saving throws, ability checks, and initiative rolls. Rolling a natural 20 is a "critical hit" (automatic success), while a natural 1 is a "critical failure." The D20 is also used in systems like Pathfinder, Starfinder, and many other RPGs.
How do you roll for stats in D&D 5e?
The most common method is "4d6 drop lowest": roll 4 six-sided dice, drop the lowest result, and sum the remaining three. Repeat 6 times for 6 ability scores. For example, rolling 3, 5, 6, 2 → drop the 2 → total is 14. This method produces scores between 3 and 18, with an average around 12.24.
What are the different types of dice?
Standard polyhedral dice come in 7 types: D4 (tetrahedron, 4 faces), D6 (cube, 6 faces — the most common), D8 (octahedron, 8 faces), D10 (pentagonal trapezohedron, 10 faces), D12 (dodecahedron, 12 faces), D20 (icosahedron, 20 faces), and D100 (percentile die, 100 sides). The D6 is the standard die used in most board games like Monopoly and Yahtzee.
Can I roll multiple dice at once?
Yes! This roller supports rolling 1 to 10 dice simultaneously. Select your dice type, use the quantity selector or type a number, and click Roll. The individual result for each die is shown along with the total sum. This is useful for games like Yahtzee (5×D6), D&D fireballs (8×D6), or rolling ability scores (4×D6).
What is a natural 20 in D&D?
A "natural 20" (nat 20) means rolling a 20 on a D20 before any modifiers are added. In D&D 5th Edition, a natural 20 on an attack roll is always a critical hit, regardless of the target's armor class. On ability checks and saving throws, a nat 20 is simply the best possible roll (20 + modifiers). The probability of rolling a nat 20 is exactly 5% (1 in 20).
