Roll up to 10 dice of any size or flip coins — cryptographically random
Dice Roller & Coin Flip is a free online browser-based utility designed to roll up to 10 dice of any size or flip coins — cryptographically random. All computations, processing, and rendering happen completely inside your browser client, ensuring your data is kept secure and private.
Open Roll dice, enter how many dice to roll, choose the number of sides and press Roll. You can roll 1 to 10 dice at once, and each die shows its own result with the total below. Available sizes are d4, d6, d8, d10, d12, d20 and d100.
Yes. It uses the browser cryptographically secure generator, crypto.getRandomValues, and discards values that would cause modulo bias, so every face is equally likely. Each roll is independent of the last, which means there are no streaks or hidden patterns.
The number after d is how many sides the die has. A d6 is the standard cube, a d20 is the twenty-sided die widely used in tabletop role-playing games, and a d100 gives 1 to 100, often for percentage rolls. Each result ranges from 1 up to the number of sides.
Switch to Flip coins and press Flip. A single coin shows Heads or Tails. Increase the number of coins, up to 100, to see the counts of Heads and Tails. Each flip has an equal 50% chance.
It is 1 in 6, or about 16.7%. Of the 36 equally likely combinations of two six-sided dice, 6 add up to 7, namely 1 and 6, 2 and 5, 3 and 4 and their reverses. That makes 7 the most common total for two dice.
Not in one roll. All dice in a single roll have the same number of sides. To combine types, roll one set, note the total, then change the sides and roll the other, adding the totals yourself.
