Coin Flip & Dice Roller

What is Coin Flip & Dice Roller?

The Coin Flip & Dice Roller provides an unbiased 3D virtual simulator for flipping coins (Heads vs Tails with streak counters) and rolling polyhedral tabletop dice (D4, D6, D8, D10, D12, D20, D100). Ideal for board games, Dungeons & Dragons (D&D) tabletop RPGs, probability teaching, and fair decision-making.

Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.

How to Use the Coin Flip & Dice Roller

1. 1
   Select your mode: "Flip Coins" for binary probability decisions or "Roll Dice" for polyhedral tabletop dice.
2. 2
   In Coin mode: Choose the number of coins (1 to 10) and click "Flip Coin" to watch animated 3D flips with Heads/Tails statistics.
3. 3
   In Dice mode: Choose your dice type (D4, D6, D8, D10, D12, D20, D100), select dice quantity (1 to 10), and set an optional modifier (+/- integer).
4. 4
   Click "Roll Dice" to generate random rolls, view individual die faces, and inspect the combined total sum and roll history.

Formula & Calculation Logic

Employs W3C Web Cryptography API CSPRNG sampling to guarantee non-predictable, mathematically uniform distributions across all polyhedral dice geometries with zero physical bias.
