About Rolling Dice
Dice are polyhedral objects used for generating random numbers, most commonly in games. Standard dice are cubes with 6 sides (D6), but dice with 4, 8, 10, 12, 20, or even 100 sides are frequently used, especially in tabletop role-playing games (RPGs).
Dice notation often uses the format XdY
, where X
is the number of dice to roll and Y
is the number of sides on each die (e.g., 2d6
means roll two 6-sided dice; 1d20
means roll one 20-sided die).
How to Use the Roller
- Number of Dice: Enter how many dice you wish to simulate rolling.
- Number of Sides per Die:** Select a common die type (D4, D6, D8, D10, D12, D20, D100) from the dropdown, or choose "Custom..." and enter the number of sides (must be 2 or more) in the input field that appears.
- Click the "Roll Dice" button.
Interpreting Your Results
- The result rolled on each individual die is displayed.
- If you rolled more than one die, the total sum of all dice rolled is also shown.
Probability and Fairness
For a fair die, each side has an equal probability of landing face up. For a standard 6-sided die (D6), the probability of rolling any specific number (1, 2, 3, 4, 5, or 6) is 1/6. When rolling multiple dice, the distribution of the *sum* of the dice tends towards a bell curve (normal distribution), with sums near the middle being more likely than sums at the extremes.
This simulator uses a pseudo-random number generator (PRNG) to simulate the roll, aiming for a uniform distribution across the possible sides.
Uses for Dice
- Board games (e.g., Monopoly, Yahtzee).
- Tabletop Role-Playing Games (RPGs) like Dungeons & Dragons (using D4, D6, D8, D10, D12, D20).
- Wargaming.
- Games of chance.
- Random selection or decision making.
Limitations
- Uses pseudo-random generation, not true physical randomness.
- Simulates "fair" dice with equal probability for each side.
