A dice roller replaces a physical die (or several) with a random, instant digital roll — useful for board games, tabletop RPGs, classroom probability lessons, or any situation where a real die isn't on hand or a fair, verifiable random result is needed. This page covers how this dice roller works, how to roll standard 6-sided dice or a custom number of sides, and a bit of the probability math behind dice rolls.

How This Dice Roller Works
Random Number Generation Behind Each Roll
Each virtual dice roll uses a random number generator to produce a result evenly distributed across every possible face — meaning a standard 6-sided die has an equal 1-in-6 chance of landing on any number from 1 to 6 on each roll, exactly matching the odds of a fair physical die.
Rolling a Standard 6-Sided Die
Single Die vs. Multiple Dice
A single roll of a 6-sided die (the most common type, used in countless board games) returns one number between 1 and 6. This dice roller also supports rolling multiple dice simultaneously, adding the individual results together for a combined total, alongside showing each individual die result.
Rolling Multiple Dice: 2, 3, or More at Once
Example: Rolling Three 6-Sided Dice
Rolling 3 standard 6-sided dice at once might return individual results like 4, 2, and 6 — with a combined total of 12. Each roll is independent, so the individual results and their sum both display, which matters for games where individual die values (not just the total) affect the outcome.
Custom Dice Roller: Any Number of Sides
Setting a Custom Number of Sides
Beyond the standard 6-sided die, this dice roller supports a custom number of sides — entering any number (4, 8, 10, 12, 20, 100, or any other value) rolls a virtual die with that many faces, evenly distributing results across the full range. This custom dice roller functionality covers tabletop gaming dice, classroom probability exercises with non-standard dice, or any other situation calling for a die outside the standard 6-sided option.
D20 and Tabletop Gaming Dice
D20, D12, D10, D8, D4 — Common Tabletop Dice
Tabletop role-playing games commonly use a full set of polyhedral dice beyond the standard 6-sided die: a d20 (20-sided, used for most core action checks), d12, d10, d8, and d4. This dice roller's custom-sides feature covers all of these standard tabletop dice types by simply entering the corresponding number of sides, functioning as a full virtual replacement for a physical dice set.
Why Use a Virtual Dice Roller Instead of Physical Dice
Why People Search "Google Dice"
Many people search for a dice roller directly through search engines like Google, which shows a built-in dice-rolling widget for quick queries like this — often called "Google dice" in casual search. This calculator serves the exact same purpose: an instant, no-download dice roll available anywhere without needing to physically locate a die, useful for remote game nights, quick decision-making, or any situation where a physical die isn't available.
The Math Behind Dice: Probability of Rolling Dice
Odds of Specific Totals on Two Dice
The probability of rolling dice is straightforward for a single 6-sided die: a 1 in 6 chance for any face. Rolling two dice together changes the odds in an interesting way — while there are 36 possible combinations (6 × 6) when rolling two dice, the totals aren't evenly distributed. A total of 7 is the most likely outcome (6 out of 36 combinations produce a 7), while a total of 2 or 12 is the least likely (only 1 combination each). This is why games that use two-dice totals (like many board games) tend to cluster around 7 far more often than extreme totals like 2 or 12.
Frequently Asked Questions
How does this dice roller work?
It uses a random number generator to produce a result evenly distributed across every face of the die, matching the odds of a fair physical die.
Can I roll more than one die at a time?
Yes. Multiple dice can be rolled simultaneously, showing each individual result along with the combined total.
Does this support custom dice with any number of sides?
Yes. Any number of sides can be entered, covering standard tabletop dice such as d4, d8, d10, d12, and d20, as well as any other custom die.
Is this the same as the dice roller shown in Google search results?
It serves the same purpose, an instant, no-download dice roll, whether accessed directly on this page or found through a search.
What are the odds of rolling a specific total with two dice?
With two 6-sided dice, a total of 7 is the most likely outcome, with 6 of 36 possible combinations, while totals of 2 or 12 are the least likely, with only 1 combination each.
Can I use this for tabletop RPGs like D&D?
Yes. Setting the number of sides to 20, 12, 10, 8, or 4 covers the standard polyhedral dice set used in most tabletop role-playing games.
Is this dice roller free to use?
Yes. It is free, requires no sign-up, and rolls dice instantly with no download needed.
