About randomness
The tool uses the browser's secure random number generator and results are never sent to a server. Each roll is independent; earlier rolls do not affect the next one. Rolling three sixes in a row does not change the chance that the fourth is a six.
Dice notation: what does 2d6 mean?
Board games and role-playing games write dice in a short notation. The first number is how many dice, and the number after the d is how many sides: 2d6 means two six-sided dice, 1d20 one twenty-sided die.
A number added at the end is added to the total: 1d20+3 means roll a twenty-sided die and add 3. To follow a rule written this way, set the number of dice and sides in the tool, then add the extra value to the result yourself.
