A Free Online Dice Roller
Built for Tabletop Gamers
D4, D6, D8, D10, D12 and D20 with realistic 3D animations and cryptographically fair rolls. Perfect for D&D, Pathfinder, World of Darkness, Shadowrun, Call of Cthulhu and every system in between.
Open the Dice Roller →If you've ever sat at a tabletop with a Dungeon Master and a character sheet, you already know the feeling: that small, irreducible thrill of letting a polyhedron decide your fate. The crack of a freshly-tossed D20 hitting the table is the soundtrack of half a century of role-playing.
WheelNamer's dice roller was built with tabletop gamers in mind. Every die in the standard seven-piece polyhedral set is rendered in real-time 3D with proper physics — D4 tetrahedra that land point-up, D8 octahedra and D12 dodecahedra with their authentic face shapes, the unusual pentagonal-trapezohedron D10 with its kite-shaped faces, and a heavyweight D20 that tumbles its full twenty triangular sides before settling. Pip placement and opposite-face numbering follow real-dice conventions, so an in-the-know player can read the result the same way they'd read a die from their own bag.
The randomness comes from crypto.getRandomValues() — the same source banks use for cryptographic keys. No seeded PRNGs, no patterns, no "smart" tweaking. Every roll is as fair as the laws of physics allow. (Sceptical? Try our 100,000-spin proof test.)
Every die in the bag — and what gamers use it for
A quick tour of the standard seven-piece polyhedral set as it shows up at the table.
D4 — Small weapons, low-damage spells
Tetrahedron
The pointy four-sided die — the smallest in the set. The D4 is used for the lightest weapons (daggers, slings, darts), Magic Missile damage, Bless dice in D&D, and as the hit die for Wizards and Sorcerers. It also crops up as a step-down die in escalating-die systems like Savage Worlds, where rolling a D4 means a character has only minimal training in a skill.
D6 — Damage, dice pools, ability scores
Cube
The classic cube — by far the most-used die in tabletop gaming. In D&D it covers shortswords, scimitars, sneak attacks and Fireball (8d6!). In ability-score generation you'll see the famous 4d6-drop-lowest method. Outside D&D, dice-pool systems live and die by the D6: Shadowrun players throw fistfuls of 10-15 dice in a single roll, Blades in the Dark resolves every action with a pool of D6s, and classic Warhammer 40,000 saving throws are read on the humble six.
D8 — Mid-tier weapons and healing
Octahedron
Eight triangular faces. The D8 powers longswords, battleaxes, mauls and rapiers — anything in the middle weight of the D&D weapon table. It also handles moderate healing magic (Healing Word, Cure Wounds), Cleric and Bard hit dice, and many class-specific spell effects. In Savage Worlds the D8 is the 'above-average' attribute die — a step up from competent into genuinely skilled.
D10 — Percentile rolls, World of Darkness, hit dice
Pentagonal trapezohedron
The only die in the set that isn't a Platonic solid. The D10 numbers 0–9, and you'll get two in a standard set so you can roll percentile (D100) — one for tens, one for units. Beyond percentile, the D10 is the heartbeat of the Storyteller / Storytelling System: Vampire: The Masquerade, Werewolf, Mage and Exalted all build dice pools of D10s where any 8+ counts as a success. Cyberpunk Red, Call of Cthulhu (percentile) and Fighter/Paladin hit dice round out the D10's job list.
D12 — Heaviest weapons, Barbarian hit dice
Dodecahedron
Twelve pentagonal faces. The D12 has one big job in D&D: the raging Barbarian's greataxe. It's also the hit die for Barbarians (the highest in the game), and shows up in some larger weapons like the heavy lance. Less common than its siblings in D&D, but in step-die systems like Savage Worlds it's the top of the ladder — D12 means peak mastery, the kind of character who can probably solo a dragon.
D20 — The decider — attacks, saves, skill checks
Icosahedron
The signature die of tabletop gaming. Gary Gygax chose the D20 for D&D specifically because every face has a clean 5% probability — making it instantly intuitive for a Dungeon Master to set difficulties. In modern 5e and Pathfinder, the D20 decides almost every meaningful action: did your sword swing connect, did your saving throw beat the dragon's breath, did your stealth check work? A natural 20 is a triumph, a natural 1 is a comedy of errors — and somewhere in between, every story turns on the bounce of those 20 triangular faces.
Popular RPG systems and the dice they use
WheelNamer's dice roller supports all the dice these systems need — and lets you roll up to 12 of any one die at once for true dice-pool play.
Why use an online roller at all?
Physical dice are the soul of tabletop, no argument there. But there are real moments when a digital roller earns its keep. Online play over Roll20, Foundry or Discord obviously needs one — every player projecting their roll onto a shared screen keeps it fair. Combats with huge dice counts (a Fireball spell, an 8d6 sneak attack, a Shadowrun decker's hacking pool) take seconds rather than minutes when you can fire off twelve dice in a single click.
Travel and convention play — when your dice bag is at home, or you just want to keep a session moving while the DM resolves an NPC's turn. New players who haven't bought a set yet can join in immediately. And honestly, for any DM running a high-prep encounter, having a digital roller on a second screen for monster turns frees your hands and your attention for the players who are actually in front of you.
WheelNamer keeps a roll history below the dice so you can prove a result, audit your luck, or settle the inevitable "wait, what did I roll?" moment. And because it's all in the browser, there's nothing to install — just open the page and start rolling.
