Coin Flip
← All toolsFlip a coin the moment you need one — heads or tails, chosen with cryptographic randomness and shown with a real 3D flip. Flip a batch at once when you need more than one call, and keep a running tally as you go.
Heads
Tails
Heads 0
Tails 0
How to use the Coin Flip
- Choose how many coins to flip at once — from 1 up to 10.
- Click “Flip” and watch the coin tumble to a result.
- For a single coin, the result reads Heads or Tails; for a batch, you'll see the split, e.g. “6 heads, 4 tails”.
- The running tally below keeps count across every flip until you reset it.
FAQ
- Is this really 50/50?
- Yes — each flip draws one bit of cryptographic randomness (crypto.getRandomValues), giving heads and tails an exactly equal chance every time, independent of any previous flip.
- If I just got 5 heads in a row, is tails more likely next?
- No — this is the gambler's fallacy. Each flip is completely independent of the last; the coin has no memory. Five heads in a row is unlikely as a run, but the sixth flip is still exactly 50/50.
- What does flipping a batch show me?
- Flipping more than one coin at once shows how many landed heads versus tails in that batch, and adds all of them to the running tally below.
- Does the tally save between visits?
- No — the tally is only kept for your current visit to the page and resets when you reload or click Reset tally.
