Roll virtual dice online for tabletop games, RPGs, or decisions. Supports standard D6, d4, d8, d10, d12, and d20 dice with automated totals, modifiers, and rolling history.
Virtual dice rollers are essential for tabletop roleplaying games like Dungeons & Dragons, board games, and random decision-making. Our free online Dice Roller allows you to roll standard 6-sided dice or full sets of RPG dice (d4, d6, d8, d10, d12, d20). You can choose the quantity of dice to roll, see individual roll results, get a total sum, and view your roll history.
Each die roll is calculated using an independent random integer generator that simulates a fair, uniform distribution (equal probability for each face). The results are logged in real time directly in your browser, providing a convenient alternative to physical dice.
The virtual dice roller uses a random number generator script that selects an integer between 1 and the number of sides on the selected die. Each face has an equal probability of being selected, simulating a fair roll.
The letter 'd' stands for die, and the number represents the number of sides on that die. For example, a d6 is a standard 6-sided cube, while a d20 is a 20-sided icosahedron widely used in RPG games.
In D&D 5e, rolling with advantage means rolling two d20s and taking the higher result. Rolling with disadvantage means rolling two d20s and taking the lower result.
The expected average of a standard 6-sided die (d6) is 3.5. You calculate this by adding all faces (1+2+3+4+5+6 = 21) and dividing by the number of faces (21/6 = 3.5).
