What Is the Coin Flip & Dice Roller?
The Randora Coin Flip & Dice Roller is a virtual randomisation tool covering everything from a simple coin flip to complex multi-dice rolls. It supports coin flips, standard RPG dice (D4, D6, D8, D10, D12, D20), rolling multiple dice of the same type at once (2–10 dice), and fully custom dice with any number of sides from 2 to 1,000. A roll history panel shows your last 20 results for the session, and each roll displays the probability of that outcome.
Standard RPG Dice
The generator covers the full standard polyhedral dice set used in tabletop role-playing games: D4 (tetrahedral), D6 (standard six-sided), D8 (octahedral), D10 (pentagonal trapezohedron), D12 (dodecahedral), and D20 (icosahedral — the classic D&D check die). Each die displays its probability in the result.
Multi Dice Mode
Roll 2–10 dice of the same type at once. The result shows each individual die value plus the total sum — perfect for damage rolls, stat generation (roll 4d6 drop lowest), and any game mechanic requiring multiple dice at once.
Custom Dice
Enter any number of sides for a completely custom die — useful for unusual probability distributions, school activities, custom game mechanics, and generating random numbers within a specific 1-to-N range where N is your custom side count.
