A straight-up wager can clear the 500-chip target in one hit; 15 chips returns 525 profit. I will adjust the stake after misses so any later hit still reaches the target.

A 15-chip straight-up win gains 525 chips, reaching the 1,500 target immediately. This preserves enough bankroll for a straight-up attempt on every remaining spin.

A 16-chip straight-up win yields 560 chips, immediately reaching the 1,500-chip target. This preserves the maximum number of independent target-reaching attempts across the remaining spins.

A maximum straight-up wager provides an immediate path above the target; all pockets are equally likely.

A 19-chip straight-up win reaches the target immediately. Using the minimum target-reaching stake preserves the most bankroll for repeated independent attempts if this spin misses.

A 19-chip straight-up win reaches the 1,500-chip target immediately, while preserving enough bankroll to make the same target-reaching attempt on every remaining spin.

A 20-chip straight-up win nets 700 chips, enough to reach the target from 816. This preserves bankroll for the maximum number of independent attempts over the remaining spins.

A 21-chip straight-up win adds 735 chips, immediately clearing the 1,500-chip target. This is the smallest single straight stake that can reach the target from the current bankroll.

A 21-chip straight-up win clears the 1,500-chip target immediately, while keeping the miss cost low enough to preserve repeated attempts over the remaining spins.

A maximum straight-up wager provides the strongest chance to clear the target immediately, while preserving several independent attempts if it misses.

A 25-chip straight-up win would raise the bankroll above the 1,500-chip target immediately. Repeating the minimum target-clearing straight bet preserves as many remaining attempts as possible.

Three straight-up bets at 28 each would each clear the target if hit, maximizing immediate coverage while preserving chips for further attempts.

A maximum straight-up wager gives the best chance of reaching the target immediately; any straight-up number has equal probability.

A straight-up hit is the only single-spin route to the target from this bankroll. I stake the minimum 31 chips that would clear 1,500 on a win, preserving attempts for the remaining spins.

A 32-chip straight-up win raises the bankroll from 414 to 1,534, clearing the target with the minimum stake that can do so in one spin.

A 32-chip straight-up win reaches the 1,500-chip target exactly, while preserving enough bankroll for all remaining spins if this attempt misses.

With only four spins left and a large gap to the target, a maximum straight-up wager provides the necessary high-upside path. Prior outcomes do not affect the independent wheel.

With three spins left and a large deficit, four 40-chip straight bets give four immediate target-reaching outcomes while preserving chips for a final high-variance attempt if this spin misses.

With only two spins left and far below the target, an all-in straight-up wager is required to retain a path to 1,500 chips. A hit immediately exceeds the target.

No chips or legal betting capacity remain, so no bet is possible.
