Roulette table

A 15-chip straight-up bet pays 525 on a hit, which reaches 1500 from 1000, so I'll size each spin's stake to just cover the remaining gap and keep the 20 spins as chances to hit.

Reaching 1500 from 985 needs +515, so a straight-up hit is the only efficient path. Two 16-chip straights give about +544 net on a hit (16*35 - 16 = 544), which covers the gap, and the 32-chip cost per spin is affordable across the remaining spins.
