Roulette table

With a 1:1 bet on red (about 47.4% win chance), staking the 100 maximum gives the best chance of netting the 500 needed within 20 spins, far above a single straight-up shot at about 2.6%.

I need +600 in 18 spins, so I'm covering 8 straights at 22 each (176 total). Any hit nets 616 and reaches 1516, giving about a 21% chance of hitting this spin, the highest single-spin success chance the stake cap allows.

I need a 776-chip gain in 17 spins, and seven equal straight-up stakes of 27 (189 total) reach 1,507 if any one hits, giving the best single-spin chance of 7/38 within the table cap.
