Tabletop roll room

Roll the dice before the table loses the thread.

A fast 3D dice roller for the moments that actually happen in play: a D&D attack, a last-minute d100 table, a five-dice Yams turn, or a board-game roll when the physical dice have vanished.

Last table check 2d20 + 5 advantage call, keep the higher d20 at the table

Roll setup

Choose the throw

Use the quick notation field when a rulebook says “roll 5d6+2”, or adjust the dice by hand.

Dice notation

Supports d4, d6, d8, d10, d12, d20, and d100. Choose d100 style only when you roll a 100-sided die.

Modifier

No account. No shared log. Roll history lives in this tab only, which is enough for a table check and safer than pretending to be an official record.

Ready to roll: 1d6

The tray is clear. Call the roll.

Method, limits and evidence

Two execution paths, one visible result.

With WebGL physics available, the dice are thrown and the result is read from each uppermost face after the bodies settle. Reduced-motion, non-WebGL, large-roll and error fallbacks instead use the logical generator: crypto.getRandomValues with rejection mapping when available, or Math.random as a compatibility fallback. The receipt records the result produced by the path that actually ran.

Known boundaries

Use this for casual tabletop play. It must not be used for real-money gambling, regulated drawings or decisions with legal, financial or safety consequences.

Session-only history

Rolls stay in this tab and disappear when it is reloaded. Clear removes the visible session log immediately.

Verified paths

Checks cover top-face mapping in WebGL, logical fallback ranges, modifiers, physical and percentile d100 modes, history, keyboard focus, motion reduction and narrow mobile layouts.
