Roll a d20, 3d6 or an ability score
Use d20 for a single twenty-sided roll and 3d6 for three six-sided dice added together. In 4d6dl1, one lowest die is crossed out before the total is calculated. Presets also cover advantage and disadvantage, and recent rolls stay visible during this session.
3d6+2 → three six-sided dice, plus 2. Possible total: 5–20.

Good to know
How do I roll with advantage or disadvantage?
Use 2d20kh1 to keep the higher of two d20 results, or 2d20kl1 to keep the lower. The result shows which die was retained.
Are all 3d6 totals equally likely?
No. Each die face is equally likely, but middle totals have more combinations. A total of 10 or 11 occurs more often than 3 or 18. Use the random number generator when you want a uniform integer range.
