Flip a coin: heads or tails

Two halves, one spin: Heads in gold, Tails in silver, with even odds every time.
Each half covers exactly 180 degrees, and the wheel is locked, so nobody can tilt the odds by adding a side or changing a weight. Where it stops comes from your browser’s cryptographic random numbers.
A coin toss settles small questions fast: who serves first, who picks the film, which of two plans to try. Spin three times for best of three; the results list keeps track.
Want to watch a real coin turn over instead? Heads or Tails tosses one and counts heads, tails and streaks.
