How to Roll Dice Online
Rolling dice online is straightforward with our tool. Select your dice type from the visual selector — each die is color-coded and shaped to match its real-world counterpart. The d4 appears as a red triangle, the d6 as a classic white cube with dots, and the iconic d20 glows gold. Set how many dice you want to roll, press the Roll button or hit Spacebar, and watch the animated results.
For experienced players, the dice notation input is the fastest way to roll. Type standard notation like "1d20+5" for an attack roll with a +5 modifier, "8d6" for fireball damage, or "4d6kh3" to generate ability scores by rolling four d6s and keeping the three highest. Press Enter and the dice roll immediately.
Quick presets cover the most common D&D rolls: standard d20 attack rolls, d8 damage, stat generation (4d6 keep highest 3), advantage (2d20 keep highest), and disadvantage (2d20 keep lowest). One click to configure and roll simultaneously.
The dice pool system lets you mix any combination of dice types. A paladin's divine smite might need 1d8 (weapon) + 2d8 (smite) + 1d6 (hunter's mark) — add each die type separately and roll them all at once. Individual results show on each die with the total displayed prominently below.
Every roll is saved to your history log with timestamps and full details. During long combat encounters, you can scroll through past rolls to verify results. Click any history entry to instantly re-roll the same configuration — no need to reconfigure your dice pool for repeated attacks.
The tool uses cryptographically secure randomness via the Web Crypto API. Unlike basic pseudo-random generators, crypto.getRandomValues() draws entropy from hardware sources, ensuring every face of every die has a perfectly equal probability. Your rolls are as fair as mathematically possible.
Frequently Asked Questions
How do I roll dice online?
Select your dice type (d4 through d100), set the quantity, and press Roll or hit Spacebar. You can also type dice notation like '2d6+3' directly. Results appear with satisfying animation and are saved to your roll history.
What dice are available?
All seven standard RPG polyhedral dice: d4 (tetrahedron), d6 (cube), d8 (octahedron), d10 (pentagonal trapezohedron), d12 (dodecahedron), d20 (icosahedron), and d100 (percentile). You can also create custom dice with 2 to 1,000 faces.
Can I roll multiple dice at once?
Yes. Set the quantity to roll multiple dice of the same type, or use Add Dice to mix different types in one roll. For example, 2d6 + 1d8 for a longsword damage roll with extra damage.
What does advantage and disadvantage mean?
In D&D 5e, advantage means rolling two d20s and taking the higher result (2d20kh1). Disadvantage means taking the lower result (2d20kl1). Both are available as quick presets.
Is this roller fair for real games?
Absolutely. We use crypto.getRandomValues(), a cryptographically secure random number generator. Every face of every die has exactly equal probability, making results provably fair and suitable for any tabletop game.
Can I see my previous rolls?
Yes. The roll history stores your last 50 rolls with timestamps, notation, individual die results, and totals. Click any past roll to re-roll the same dice configuration.
