よくある質問
Is the flip truly 50/50?+
Yes. The result is generated using a cryptographically secure random number generator, giving you a perfect 50/50 probability - unlike a real coin which can have micro-biases from weight distribution.
Why does my history show uneven results?+
This is completely normal and expected. In small sample sizes, streaks and clusters are statistically inevitable. As you flip more, the ratio converges toward 50/50 - this is the Law of Large Numbers in action.
