About this tool
The advanced dice roller understands tabletop dice notation, so you can type rolls the way RPG rulebooks write them: 2d6+3, 4d8, 1d20 and more. It rolls the dice, applies your modifier, and shows the full breakdown.
Need a clutch attack roll? Switch on Advantage or Disadvantage to roll twice and keep the higher or lower result. With secure randomness and support for up to 100 dice of any size, it is built for Dungeons & Dragons, Pathfinder and homebrew games alike.
Frequently asked questions
What dice notation can I use?
Standard tabletop notation: NdS means roll N dice with S sides, plus an optional bonus. So 2d6+3 rolls two six-sided dice and adds 3; 1d20 rolls a single twenty-sided die; 4d8 rolls four eight-sided dice.
How do advantage and disadvantage work?
Pick Advantage to roll twice and keep the higher result, or Disadvantage to keep the lower — the classic 5e mechanic. The breakdown shows both rolls so you can see exactly what happened.
How is this different from the basic dice roller?
The basic dice roller uses tappable presets and shows pip faces. This advanced roller takes typed notation with modifiers and supports advantage/disadvantage — ideal for Dungeons & Dragons and other RPGs.
Are the rolls fair?
Yes. Every die is rolled with your browser’s secure random generator, so each face is equally likely and past rolls never influence the next.
