Dice Roller — Any Combination with Probability Analysis
What number will you roll?
Roll any combination of standard polyhedral dice (d4 through d100) with an optional modifier and instantly see your result, percentile rank, probability distribution, and full roll history. This isn't just a basic dice roller — it shows you what your result means. If you roll 4d6+8 and get 24, is that good? The probability panel answers that: 24 falls at the 65th percentile for that roll, meaning you'd expect to beat it only 35% of the time. Full probability distribution shows every possible total alongside its likelihood. RPG presets cover the most common D&D and Pathfinder roll types so you can jump straight into gameplay without configuring each roll manually. The roll history panel tracks your last ten rolls so you can spot patterns across a session — useful for confirming whether a weapon consistently underperforms or you are just running cold. Works on mobile during tabletop sessions or on desktop for virtual tabletop play.

Marcus is playing D&D 5e online and rolls sneak attack damage — 4d6+8. He rolls: 3, 5, 2, 6 = sum 16 + modifier 8 = 24 total. The probability panel shows 24 is the 65th percentile for this roll combination — above average but not exceptional. Roll history tracks his last 10 rolls so he can spot hot or cold streaks across the session.
