Please let me know how I can clarify my question
1 - You are giving way too much information. We do not need to know the
rules of the game or all the code. Our time to read email is limited.
The less you tell us that is not relevant the better. Also you don't
show the code for the "next level of complexity". What you should show

2 - The most obvious problem is here:
while flipCoin() != 2:
The result of the first call to flipCoin is ignored.
Each cycle of the loop results in 2 calls to flipCoin. The result of the
2nd call is ignored.

Then your expectation is misguided, given my comments regarding multiple
calls to flipCoin! You don't actually know how many tosses were made!
