Are the rolls truly random?

They use your browser's cryptographically secure random number generator, so every face is equally likely.

What is the most common total with two dice?

7, which can be made 6 ways out of 36 (16.7%). 2 and 12 are the rarest (1 in 36 each).

In short

Choose how many dice to roll and press Roll to get fair random results and their total. With two dice, 7 is the most likely total (1 in 6).

Roll any number of dice with any number of faces — d4, d6, d8, d10, d12, d20 — for board games, tabletop role-playing or a quick decision.

Rolls use the browser's cryptographic random source rather than a seeded generator, so a sequence cannot be reproduced or predicted.

What each die is for:

d20 — attack and skill checks in most role-playing systems; the average roll is 10.5.
2d6 — board games; totals cluster around 7.
d4, d8, d12 — weapon and spell damage.
d10 twice — percentile rolls from 1 to 100.
