Roulette table

Reaching +500 needs a high-payout bet. A 20-chip straight-up pays 700 on a hit and keeps the bankroll intact for later spins, so I can raise stakes later as needed.

Reaching 1500 needs about +520, so a 30-chip straight-up bet (pays +1050 on a hit) reaches the target in one hit and keeps enough bankroll to try on most of the remaining spins.

Reaching 1500 needs +550, so I chose a single straight-up at a stake small enough to last all 18 remaining spins, since one hit at 31 or more still reaches the target even on the last spin. Two straights per spin would drain the bankroll too fast to pay off.

Need +581 from 919; nine straight-ups at 22 each cost 198 and a single hit nets 594, enough to reach 1500. This covers the most numbers at the minimum stake that still hits the target, maximizing per-spin success chance.
