The roller draws each face with crypto.getRandomValues and shows the sum when you roll more than one. It does not print these odds.
Roll virtual dice online with fair, random results. Pick the number of sides (d4, d6, d8, d10, d12, d20, d100) and how many dice to roll at once. A digital dice roller is perfect when you have lost your physical dice, are playing a tabletop game like Dungeons & Dragons remotely, or just need a quick random number for a decision. This roller uses the browser's secure random source so every face is equally likely, and it shows each individual die result plus the total. Choose your dice, hit roll, and get an instant, honest result. Nothing is tracked. The outcome is generated locally each time you roll.
