Simulate coin tosses with a 3D flip animation and a full set of features for decisions, games, and probability demonstrations. Choose from four coin themes - Gold, Silver, Bitcoin, and Copper. Flip 1 to 5 coins simultaneously. Customize heads and tails labels for binary decisions like Yes vs No or Option A vs Option B. Best-of series mode (3, 5, 7, or 11) includes a live scoreboard. Auto-flip mode runs at a set interval for demonstrations. Simulation mode instantly runs up to 10,000 flips and shows the distribution - ideal for illustrating the 50/50 convergence over large samples. Statistics track win percentages, streaks, and standard deviation. All processing is 100% in-browser. No account required.
