Dice Roller
Roll a digital die by choosing its number of sides and starting the spinner. The default is a six-sided die, and the selector also supports d4, d8, d10, d12 and d20. A 1d20 roll means one draw from the integers 1 through 20. This tool shows those faces as wheel entries so the available outcomes are easy to inspect. It is suited to casual board games, tabletop prompts and probability practice where you need one die result at a time.
Your entries
6 entriesEach die rolls independently. The wheel shows the first die; the result lists every die and the total. Keep the face entries unchanged.
Equal chance for every entry. Repeated labels count as separate entries.
How to use this tool
- Choose the die size, number of dice and whole-number modifier. Keep the generated face list unchanged.
- Keep weighted mode and winner removal off for independent dice rolls.
- Choose the die size and select Roll the die.
- Copy the result if you need a record, then close the dialog or start another round.
Select the die your rules require
Choose d6 for a standard six-face result or d20 for a twenty-face result. Changing the die replaces the current entry list with the appropriate consecutive integers. The selector does not apply game-specific bonuses, critical-hit rules or character statistics. If your rules say ‘1d20 + 3,’ roll the d20 here and add three to the displayed number yourself.
Keep repeated rolls independent
For normal dice behavior, leave winner removal disabled and use equal weighting. A physical die can land on the same face twice; a digital die should also permit repeats. Removing a result creates a draw without replacement, which is a different game mechanic. Editing the faces or applying weights also changes the starting die, so restore the preset when you want standard behavior.
Understand one die versus a sum of dice
Rolling one d12 is not equivalent to rolling two d6 dice and adding them. One d12 has equal chances for 1 through 12, while two d6 dice produce totals 2 through 12 with unequal probabilities. For a two-die sum, perform two independent d6 rolls and add the results. Do not replace that process with a uniformly labeled list of totals.
Use outcomes as prompts or practice data
A facilitator can connect each die face to a task on a separate numbered list. Students can record twenty d6 rolls and compare observed counts without expecting exactly equal totals. The recent-results strip helps with a short session, but it is not a permanent record or certified audit log. Copy important results into your own notes while the session is open.
Frequently asked questions
What does 1d20 mean?
The notation means roll one die with twenty sides. Its possible results are the integers 1 to 20. Other game instructions may add modifiers or define success thresholds; those rules are separate from this tool’s random face selection.
Can I roll more than one die at once?
This version returns one die result per spin. To roll multiple dice, perform the required number of independent rolls and record them separately. For a sum, add those results afterward rather than switching to a larger single die.
Is each face equally likely?
With the standard face list, equal mode and removal off, every face has the same probability on every spin. A d6 face has a one-in-six chance; a d20 face has a one-in-twenty chance. Prior rolls do not change those probabilities.
Can this replace an official tournament dice system?
That depends on the organizer’s rules. This is a general-purpose browser tool, not a certified or tamper-evident tournament service. Obtain the organizer’s agreement before using it where a specific physical die, platform or logged procedure is required.
