Generate random numbers instantly with virtual dice!
Virtual dice let you generate random numbers from 1 to 6 without physical dice. You can roll 1 to 4 dice simultaneously for various games and activities.
Useful for dice baseball, board games, TRPGs (Tabletop Role-Playing Games), educational probability simulations, and more.
Each roll displays results with animation for a realistic dice-rolling experience, and the last 10 rolls are recorded for probability analysis.
- 1
Click roll
Press roll to see the dice animate and land on a random number.

Check result
The dice face (1–6) is displayed as a dot pattern.

Repeat as needed for games or decisions.
Example — Board game use
For games like Monopoly: roll twice and sum. First roll 4, second 6 → move 10 spaces. Press 'roll' twice consecutively.
On a fair 6-sided die, each face has equal probability. The sum when rolling n dice follows a sum of discrete uniform distributions.
Dice Usage Tips
QCan I set the number of dice faces?
This tool supports standard 6-sided dice by default. Multi-sided dice (4, 8, 10, 12, 20 for D&D etc.) support depends on the version; currently 6-sided only.
QIs the result fair with Math.random()?
Math.random() uses Mersenne Twister, which provides sufficiently uniform distribution for entertainment. For legally fairness-critical uses, crypto.getRandomValues()-based randomness may be required.
QCan I roll multiple dice at once?
Depends on the implementation. When supported, multiple dice are independent and results appear with a sum. Single-die roll is the default.
QAre roll results saved?
No server storage. Results persist only during the browser session and are lost on refresh. Record game history separately if needed.
QHow are the dice dot patterns rendered?
Each face is a 3×3 boolean grid — e.g., 1 is a center dot, 6 is three rows of two. Patterns are hardcoded to match traditional die dot layouts.
