Roulette table

A maximum-stake even-money bet gives a relatively frequent chance to build toward the 500-chip target over the 20 spins, rather than relying on a single long-shot hit.

An 18-chip straight-up win pays 630 net, enough to reach the target, while keeping the loss on a miss as small as possible.

A maximum straight-up wager offers the largest single-spin gain, giving the best chance to make substantial progress toward the target.

A 21-chip straight-up win nets 735 chips, enough to reach the target from this bankroll. Keeping the stake to the minimum that can get there preserves chips for more attempts if this spin loses.

A 22-chip straight-up win earns 770 chips at 35:1, enough to reach the 1,500-chip target. Keeping the stake at this minimum target-reaching amount preserves bankroll and future chances after a loss.

A 22-chip straight-up bet is the minimum stake that can reach the target from my current bankroll if it hits. Keeping the stake low preserves bankroll for more independent attempts.

A 23-chip straight-up win yields 805 chips, enough to reach the target from this bankroll. This is the smallest single bet that can get there in one hit, preserving chips for later attempts if it misses.

Two maximum straight-up bets on distinct pockets give the best chance of a large enough win to reach the target; roulette outcomes are independent and uniform.

A 30-chip straight-up win adds 1,020 chips, enough to reach the target from this bankroll. The minimum qualifying stake preserves as many attempts as possible, and spins are independent.

Two 31-chip straight-up bets reach the target bankroll if either number hits, while giving a higher per-spin success chance than a single qualifying bet. Previous outcomes do not affect the independent spin odds.

A straight-up 100-chip win is the only single-spin outcome that can reach the 1,500-chip target from this bankroll; every pocket is equally likely.

A 35-chip straight-up win would raise my bankroll above 1,500. This is the minimum stake that can reach the target in one hit, preserving chips for more attempts if it loses.

A 36-chip straight-up win pays 1,260 chips profit, enough to reach the target from my current bankroll. A smaller stake cannot get me there in one hit, while a larger stake would risk more without increasing the chance of success.

A 37-chip straight-up win reaches the 1,500-chip target from my current bankroll. Keeping the stake to the minimum needed preserves the most bankroll—and therefore the most chances—for later spins if it misses.

With six spins left and 194 chips, reaching 1,500 requires a large payout. Two distinct maximum-sized straight-up wagers maximize the chance of a qualifying hit this spin; past outcomes do not affect the independent wheel odds.
