How to Use
How this differs from a basic coin flip

A simple coin flip just shows heads or tails once. This tool is a full coin toss simulator with a custom heads probability, multiple coins (up to 500) tossed at once, CSV export of your results, and fullscreen mode — perfect for raffles, picking turns, seating, or games, all in your browser.

Tossing Coins

Press “Toss Coins” to flip all configured coins at once. Results are shown as Heads or Tails — more Heads means WIN, more Tails means LOSE, and equal results mean DRAW.

Setting a custom (weighted) probability

Use the slider or number input to set the Heads probability from 0 to 100%. At 50% the coin is fair; at 100% every coin lands Heads — handy for simulating a biased or weighted coin.

Tossing multiple coins at once (up to 500)

Enter a value from 1 to 500 in the input field to toss several coins together and tally the heads count. Quick-select buttons (5, 10, 30, 50, 100, 300, 500) let you set the count with a single tap.

Fullscreen Mode

Click “Fullscreen” in the top-right corner to display only the coins. Useful for presenting results on a large screen or projector (PC only).

History & CSV Export

Each toss is recorded in the history (up to 50 entries). Use “Export CSV” to save the history as a file, or “Clear History” to delete all records.

Sound Effects

Sound effects play when tossing and when the result is shown. Toggle sound on/off with the speaker icon in the top bar.
