Troubleshooting

Dice not rolling? Ensure JavaScript is enabled in your browser, as all calculations happen on the client side.
History missing? If you refresh the page or clear your cache, the local session history will be reset.
Total sum incorrect? Note that some dice (like D10) are indexed 0-9 or 1-10 depending on the system; our D10 uses the standard 1-10 range.

Pro Tips for Creators

If you're stuck between two restaurants, assign 'Heads' to one and 'Tails' to the other for a stress-free choice.
Tabletop GMs: Use the D20 roller for 'Secret Rolls' on your phone to keep the tension high at the table.

Frequently Asked Questions

Is this coin flip really 50/50?

Yes. While physical coins can have slight weight biases, our digital coin uses a random number generator that ensures an exact 50% probability over the long term.

Can I use this for Dungeons & Dragons?

Absolutely! We provide the full set of polyhedral dice (D4-D20) required for D&D, Pathfinder, and other d20-system tabletop games.

How many dice can I roll at once?

You can roll multiple dice of the same type simultaneously. The tool will display each individual die result and the calculated total sum.

Does the 'Heads or Tails' result get saved?

The history is only saved in your current browser session. Once you refresh or close the tab, all session data is permanently cleared.

Why use a digital roller instead of physical dice?

Digital rollers are immune to 'loaded dice' bias, can't be lost under the sofa, and allow for instant calculation of large dice pools (like 10D6).

Our professional-grade Coin Flipper and Dice Roller is designed for fairness and versatility. Whether you're settling a friendly dispute with a 50/50 heads or tails toss, or managing a complex Tabletop RPG (TRPG) session with D20 rolls, our tool provides cryptographically secure randomness. Built with a 'Privacy-First' approach, every flip and roll happens entirely on your device, ensuring a fast, ad-free, and secure experience.
