Can I roll dice for D&D and other RPGs?▼

How many dice can I roll at once?▼
You can roll up to 100 dice at once, with each die having up to 1000 sides. This covers everything from rolling 8d6 for fireball damage to massive dice pools in systems like Shadowrun.
Is this dice roller truly random?▼
Yes, the dice roller uses JavaScript's Math.random() function to generate random numbers. Each roll is independent and has equal probability for each possible outcome, just like physical dice.
Can I see my previous rolls?▼
Yes! The roll history section shows your last 20 rolls with their notation and total results. This is helpful for tracking rolls during game sessions.
What do the green and red numbers mean?▼
When rolling 1d20, a natural 20 (the highest possible roll) is highlighted in green - often a critical success in RPGs. A natural 1 (the lowest roll) is highlighted in red - typically a critical failure.
