Virtual Dice Roller
Roll up to 100 virtual dice simultaneously for board games, tabletop RPGs (D&D 5e), and probability experiments. Supports D4, D6, D8, D10, D12, D20, D100, and drop-lowest stats rolling.
Total Sum: 6
Average: 3 | Min: 2 | Max: 4 | Product: 8Probability Distribution for Rolling Two 6-Sided Dice (2d6)
When rolling two 6-sided dice, there are $6 \times 6 = 36$ possible outcomes. The sum 7 has the highest probability ($6 / 36 = 16.67\%$) because it can be produced by six combinations: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1).

How to Use the Dice Roller
- 1 Select the die type (D6 standard, D20 D&D, D4, D8, D10, D12, D100).
- 2 Choose the number of dice (1 to 100).
- 3 Optionally check "Drop Lowest Die" for tabletop RPG character attribute rolls (4d6 drop lowest).
- 4 Click the green "Roll Dice ▶️" button to view animated visual dice, sum totals, averages, and roll history.
Dice Roller — Frequently Asked Questions
Q1 Are the virtual dice rolls truly random and fair? ▾
Yes. Our dice roller uses the browser’s cryptographically secure random number generator (window.crypto.getRandomValues), ensuring completely unbiased and uniform probability distributions.
Q2 Why is 7 the most common sum when rolling two 6-sided dice? ▾
There are 36 total outcomes when rolling two dice. The sum of 7 has 6 distinct combinations (1+6, 2+5, 3+4, 4+3, 5+2, 6+1), giving it the highest probability of 6/36 or 16.67%.
Q3 What is the "4d6 drop lowest" method in Dungeons & Dragons? ▾
In D&D 5e character creation, players roll four 6-sided dice and discard the lowest single roll, summing the remaining three dice to generate an ability score between 3 and 18.
