Coin flip wheel
Choose heads or tails with a fair two-choice wheel, plus optional recorded result reading. Use it to choose who goes first or to repeat a simple probability experiment. Keep both sides eligible if you want each spin to use the same two outcomes.

How it works
- The browser chooses an entry using cryptographic randomness with rejection sampling. Every remaining line has one chance; repeating a line gives that choice additional chances. The wheel animation presents the result already chosen.
- Choices and results are processed in this tab and are not automatically saved or uploaded. This is a casual selection tool, not a certified lottery or a prediction of real outcomes.
Assumptions and limitations
A digital random draw, not a physical coin simulation or gambling service. Editing, duplicating or removing entries changes the probabilities. Short runs need not split evenly.
How to use this tool
Review the choices, select a choice set when offered, and spin. The result card lets you spin again, remove that occurrence or close. Editing the list changes the candidate pool; a new choice set restores its reviewed defaults. Sound, confetti and animation have separate switches.
When to use it
Use a simple binary draw to decide who starts, settle a casual choice or demonstrate equal probability.
Included choices
- Heads
- Tails
Worked examples

Use a coin toss as a fair tie-breaker
