This is a bold-play approach: ten straight-up bets of 20 chips each give a 10/38 (about 26%) chance that one hit takes the bankroll to 1520, reaching the target this spin. It also keeps enough bankroll to try similar target-reaching spreads if it misses.

I bet 21 on each of two straight-up numbers; one hit nets 714 and takes me from 800 to about 1514, just past the 1500 target. Keeping stakes near the minimum needed stretches the bankroll over roughly 13 or more attempts, giving an estimated 50% chance of reaching the target.

Two straight-up bets of 22 chips each would take the bankroll to 1506 if either hits, clearing the 1500 target. Keeping stakes near the minimum needed to reach the target leaves many more shots across the remaining spins.

A single straight-up bet of 23 pays 805 and gets me to exactly 1519 if it hits. Keeping the stake at the smallest size that still reaches the target spreads the bankroll over the most spins, giving roughly a 35% chance of reaching 1500 over the remaining spins.

Two straight-up bets of 24 each: if either hits, the bankroll reaches 1,507 and meets the target. This limits the cost of a miss to 48 chips and leaves enough bankroll for many more attempts over the remaining 15 spins.

Bold play: six straight-up bets of 29 each. A hit takes the bankroll to 1513, clearing the 1500 target in one spin, with about a 15.8% chance this spin.

Only reaching 1,500 counts, so I'm making the smallest straight-up bet whose win clears the target (469 - 30 + 1,080 = 1,519). This spreads the bankroll over as many 1-in-38 attempts as the remaining spins allow.

Reaching 1500 from 439 needs a high-payout bet, so I'm staking the smallest single straight-up amount (31 at 35:1) that clears the target if it hits. Keeping the stake minimal preserves bankroll for as many attempts as possible over the remaining spins.

Bold play: five straight-up bets of 36 chips each, so any single hit takes the bankroll to 1524 and clears the 1500 target. That gives a 5/38 chance this spin while keeping 228 chips for later attempts.

I need +1272 chips in 11 spins. The smallest single straight-up stake that reaches 1500 on a hit is 37 (228 + 37×35 = 1523). Staking only that much each spin gives the most winning chances from this bankroll.

I need at least +1309 from 191 chips. Four straight-up bets of 41 each (164 total) mean any hit leaves 27 + 41×36 = 1503, reaching the target with about a 4/38 (10.5%) chance this spin, while keeping 27 chips in reserve if all miss.

With only 27 chips and 9 spins left, reaching 1500 requires maximum variance. An all-in straight-up bet turns a win into 972 chips, a strong base for finishing the climb under the 200-per-spin cap.
