I just booked my offer at Cosmo with $450 in promo chips (one time use) for June. Originally, I was going to bet it all in one hand in baccarat or roulette (black/red). Then I thought about placing 18 $25 chips on numbers in roulette (single 0). If I put an extra $25 chip from my pocket, that's 19 units placed over 37 spots. I would have a >50% chance to win $875 minus my $25, total $850. What do you think about this strategy for a quick bet with promo chips? I'm not a big roulette player.
