Roll a dice online

Which dice can I roll here?

All seven of the common gaming dice: the four-sided d4, the ordinary d6, and the d8, d10, d12, d20 and d100. That covers a standard role-playing set plus percentile rolls. You can roll up to ten dice of one type per throw, and the Rolls counter tells you how many throws you have made this session.

Each throw uses one die type. If your game asks for mixed dice, such as 1d8 plus 1d6, roll each type separately and add the two totals yourself.

Rolling dice for tabletop RPGs

Games such as Dungeons & Dragons use the d20 for most checks and attacks, and smaller dice for damage. A few tips for using this roller at the table:

• Advantage and disadvantage. Set 2 dice and d20. Both results are shown side by side, so take the higher or the lower as the rules say.
• Damage rolls. Choose, for example, 3 dice and d6 for 3d6, and the total is ready to read out.
• Percentile rolls. Physical sets use two ten-sided dice for this. The d100 option gives you a number from 1 to 100 in a single roll.
• Rolling in the open. Share your screen or keep the history visible so the table can see each result as it lands.

What is the most likely total with two dice?

Seven. With two six-sided dice there are 36 equally likely combinations, and six of them add up to 7 (1+6, 2+5, 3+4, 4+3, 5+2 and 6+1). That gives 7 a chance of 6 in 36, or 1 in 6. The extremes are rare: a 2 or a 12 can each happen only one way, so each has a 1 in 36 chance.

This curve is why many board games built on two dice treat 7 as special: it is the number you will see most often. A single die is different. Every face from 1 to 6 is equally likely, so a d6 on its own is flat, and a number wheel from 1 to 10 is a better fit when you need a flat spread over a different range.

Lost the dice from a board game?

It happens to every family game box. Put this page on a phone in the middle of the table and set the number of dice the game needs: two d6 for most classic board games, or five d6 for games where you roll a handful. There is no way to hold some dice and re-roll the rest, so when a game lets you keep dice, set the count to the number you are re-rolling and add the kept ones yourself.

If your game also needs someone to start, use the who goes first wheel, or flip for it with the coin toss when there are only two players.

Dice or random number generator?

Dice are best for game rules written in dice terms, like 2d6 or 1d20. If you need a number from an unusual range, such as 1 to 37, or many numbers with no repeats, the random number generator does that directly.
