Coin Toss — Heads or Tails

Is this coin toss fair?

Yes. Every flip uses your browser's cryptographic random generator (crypto.getRandomValues), so heads and tails each have exactly a 50% chance and previous results never influence the next one.

Uses

• Deciding who goes first in a game or match
• Settling a tie or a simple yes/no decision
• Teaching probability — flip 100 times and watch the ratio approach 50/50
