Automatic online coin flipper

Simulate flipping a coin one or multiple times with this coin flipper app. You can flip the coin many times at once (up to 200,000 times) and receive the total number of heads and tails, and the percentage of heads and tails. Just choose the number of flips in the options and click the flip coin button.

The coin flipper uses a random number generator (mt_rand) to determine if heads or tails is the result of each simulated coin flip. The results are stored and the averages and percentages are included in the results.
