Introducing the Dice Roller — D4 to D100, Modifiers and All

Physical dice are easy to lose and never around when you need them. The new Dice Roller puts a full set in your browser: every standard polyhedral die, custom counts, modifiers, and a clear breakdown of each roll.

What it does

• All seven dice: D4, D6, D8, D10, D12, D20, and D100 (percentile).
• Custom counts: roll up to 100 of any single die at once.
• Mix dice types: combine groups like 2d6 + 1d20 in one throw.
• Modifiers: add a positive or negative flat bonus to the total.
• Full breakdown: see each individual die face, every subtotal, and the grand total — plus the theoretical range.
• Roll history: recent throws are kept so you can compare them.
• Client-side: nothing you roll ever leaves your browser.

Why it matters

Tabletop RPGs, board games, classroom probability demos, and quick fair decisions all run on dice. A virtual roller gives you uniformly fair results on every face, shows the maths instead of hiding it behind a single number, and works on any device without a flat surface or a missing d20.
