LiveHow it works
Rolling 2 six-sided dice (2d6) can land anywhere from 2 to 12, with 7 being the statistically most common total, since more number combinations add up to 7 than to any other value.
Step-by-step guide
- Choose how many dice to roll and how many sides each die has.
- Click "Roll the dice."
- Read each individual result and the total.
Why 7 is the most common result on two six-sided dice
With two six-sided dice, there are 36 equally likely combinations, but multiple different combinations can add up to the same total - only one combination makes 2 (1+1) or 12 (6+6), while six different combinations make 7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1). This is a classic, hands-on example of probability distribution: totals in the middle of the possible range have more ways to occur than totals at the extremes, which is exactly why 7 comes up more often than any other total over many rolls.
Frequently asked questions
Is this truly random?
It uses your browser's standard random number generator, which is suitable for games and casual use, though not intended for cryptographic or high-stakes gambling applications requiring certified randomness.
What does "d20" or "d6" mean?
Standard tabletop gaming notation - "d" followed by a number means a die with that many sides, so d20 is a twenty-sided die and d6 is a standard six-sided die, common notation in games like Dungeons & Dragons.
Can I roll more than 20 dice at once?
This tool caps at 20 dice per roll to keep the display clean and readable - for most games and classroom activities, that's more than enough at once.
