Silly
Kind of a silly game. With 10 minutes to win the money, it's not going to make for an enduring round of smart gambling. I did the standard 2 tier bet (64.8% chance to win) and beat it within the first two minutes. Still it's mildly amusing.
I think it would have been more entertaining if you had to make $100,000 or even $1,000,000 with a whole lot more time to make it.
