Then we decide on a cutoff.

Sure, if you tell me exactly what the finite time is.

It's an even game for 4 throws, favours me for higher. You must show me that
you have $8.

It's an even game for 10 throws, favours me for higher. You must show me
that you have $512.

It's an even game for 20 throws, favours me for higher. You must show me
that you have $524,288.

This is on par with typical lotteries. Odds of winning the biggest jackpot
is almost one in a million, with more probable smaller prizes.

> $100 ?


It's an even game for 200 throws, favours me for higher. You must show me
that you have over $8e59.

Even then, I don't think I'd play, as I don't know where I'd put that money
if I win.

The progression on maximum winnings possible might be a clue why.
