Frequently Asked Questions
What dice types are supported?
We support all standard RPG dice: d4, d6, d8, d10, d12, d20, and d100 (percentile). Tap a die icon to select it, then press Roll!
Can I use dice notation like 2d6+3?
Yes! Open the Advanced: Dice Notation section at the bottom, type standard notation (e.g., '2d6+3', '1d20+5', '4d6') and press Enter or click Roll.
How are critical rolls shown?
Maximum rolls (like a natural 20 on a d20) are highlighted in green with a 'MAX!' label, while natural 1s are shown in red with 'MIN!', making it easy to spot critical results.
Is the dice roller fair?
Absolutely! We use the Web Crypto API with rejection sampling to ensure perfectly uniform distribution. Every face has an exactly equal probability of appearing.
Can I see my previous rolls?
Yes, the Roll History section keeps track of your last 20 rolls, showing the notation used and the total result for each.
What does the Bonus (+/-) do?
The Bonus is a number added to (or subtracted from) your dice roll total. For example, rolling a 4 on a d6 with a +2 bonus gives a total of 6. In tabletop RPGs this is commonly called a 'modifier'. Use positive values for bonuses and negative values for penalties.
