About this generator
Every tabletop session runs on dice: a single d6 for a board game, a fistful of d20s and d12s for a Dungeons & Dragons combat round. This roller handles any number of dice, any number of sides, and an optional flat modifier, so a "d20+5" attack roll or a pool of six d6 damage dice comes back instantly instead of requiring an actual dice bag.
The same mechanic doubles as a probability lesson: roll one d6 enough times and the six faces spread out evenly; roll two d6 together and 7 turns up far more often than 2 or 12, simply because more combinations add up to seven. Outside of games, dice are also a low-stakes way to randomize a decision (pick a restaurant, set turn order, assign chores) without any of the ceremony of an actual roll.
Tables that use house rules like exploding dice (reroll and add on a max face) can still apply them here manually: roll again whenever a die lands on its highest value, exactly as you would at the table. Because every die is generated independently through a proper random source, it's a fair stand-in for the physical version during remote or hybrid sessions.
Frequently Asked Questions
What dice sizes are supported?
Any number of sides you choose (d4, d6, d8, d10, d12, d20, or a custom value), rolled in any quantity, with an optional modifier added to the total.
Is this fair enough to replace real dice at the table?
Each roll comes from a proper random number generator, making it a legitimate substitute for physical dice, particularly for remote games where passing dice around isn't an option.
Can I add a modifier like D&D's d20+5?
Set a flat bonus or penalty and it's applied to the roll total automatically, matching standard dice-plus-modifier notation.
Does rolling multiple dice show each individual result?
It does: you get every die's value along with the summed total, useful for damage rolls or multi-die ability checks.
Can it handle exploding dice or reroll-on-max rules?
Not automatically, but you can apply the house rule yourself: reroll and add whenever a die shows its maximum face, same as with a physical one.
Is each die independent of the others in a roll?
Always. Every die in a batch is generated on its own, just like a handful of physical dice; one result never skews another.
