Roulette table

This uses bold small straight-up bets sized so that a single hit reaches 1,500 chips (34*15 = 510 net against a 500 deficit). Keeping the cost low lets the bankroll last most of the 20 spins, for roughly a 64% chance of reaching the target.

Every bet has the same house edge, so staking only what one hit needs keeps total wagering low. Four 17-chip straights turn one hit into 1514 chips, above the 1500 target, while giving a reasonable chance per spin over the 19 remaining spins.

This spin can finish the job on its own: any one hit pays 684 against 76 staked, a net +608 that lifts the bankroll from 902 to 1,510, just over 1,500. The chance of a hit is only about 10.5% (4 of 38 pockets), but the stake is small enough to leave plenty of room for later spins.
