Pretty generous house to provide even wagers:

> 0.01 CHA 1% 99X -0.01 CHA

Except that 99X means that if you win, you get a 0.99CHA payout, for a gain of only 0.98CHA, making it worse than even.

A 1% chance to get a 99x payout still has a negative expected value, no? 99 x 0.01 x original bet = 0.99 x original bet
