Dice Roller

The dice bag is always in the other room. This roller covers the full tabletop set — d4, d6, d8, d10, d12 and d20 — and rolls up to ten dice at once. d4 and d6 are real 3D cubes that tumble before landing on a face; the higher-sided dice flip as faceted chips. Under the hood each die is an independent draw from a cryptographic random source using rejection sampling, which eliminates the modulo bias that quietly skews naive dice scripts toward low numbers.

Every die lands on its own spot in the tray so individual results stay readable, and the sum adds itself up for damage rolls, stat generation and classroom probability demos. No physical dice were harmed, lost under the sofa, or accused of being cursed.
