WheelJar is a free set of random-decision tools built as a small independent project. Wheels, coin flips, dice, number and word generators, team makers and Secret Santa draws — thirty-one tools that all answer the same question in different shapes: which one?

Every tool runs entirely in your browser. There is no account, no saved history and no server doing the drawing on your behalf. Randomness comes from crypto.getRandomValues, the generator browsers use for encryption keys, with rejection sampling to keep every outcome equally likely and Fisher–Yates for anything that shuffles. The full write-up is on the methodology page.

The guides exist because the tools attract a particular kind of question — is the wheel really random, is a coin toss actually 50/50, how do I run a giveaway nobody can argue with — and those deserve a proper answer with the arithmetic shown rather than a reassuring sentence.
