This covers three straight-up numbers with 17 chips each. Any hit lifts the bankroll to 1,561 in one spin, and a miss costs only 51, which leaves plenty of room to keep trying over the remaining 19 spins.

I need 551 more chips, so I'm using three 17-chip straight-up bets: any single hit nets 561 and reaches the target in one spin. Keeping the stakes small leaves enough bankroll for many more attempts over the remaining 19 spins.

We need about +600 chips and are capped at 200 per spin, so I'm using the full limit on two bets with a high spread. A dozen plus a column pays +400 if both hit (4/38), +100 if one hits (16/38) and -200 if neither does, which gives a better chance of reaching 1500 in 18 spins than low-variance play.

A single hit on either straight-up bet takes the bankroll to 1514, which clears the 1500 target. Spreading small straight-up bets over the remaining spins gives a better chance of reaching the target than grinding low-payout bets against the house edge.

Two 25-chip straight-up bets cost 50, and a hit brings the bankroll to exactly 1,500. Small straight-up bets stretch the 650-chip bankroll across as many 35:1 shots at the target as possible over the remaining spins.

I need +900 in 15 spins, so I'm betting two small straight-ups sized so that one hit reaches about 1518. That keeps enough bankroll to buy many more single-number chances before the session ends.

I need +954 in 14 spins, and only reaching 1500 counts. Two straight-ups at 29 each mean a single hit lands at 1532, while keeping the stake small enough for many more attempts.

I need +1012 in 13 spins, so I'm taking two straight-up bets of 30 each. Either hit lifts the bankroll past 1500, and this sizing spreads the remaining chips over as many shots as the spin limit allows.

At 428 chips with 12 spins left, a 31-chip straight-up bet is the smallest stake that reaches 1,500 in one hit (a win brings the bankroll to 1,513). Staking only the minimum needed keeps chips for as many attempts as possible, which gives the best chance of hitting the target.

I need +1103 from 397 with 11 spins left, so the best route is the fewest possible straight-up hits. Two straights at 33 each would net 34*33=1122 on a hit, reaching the 1,500 target while keeping enough chips for several more attempts.

A straight-up bet of 34 wins 1,190 chips, which is just enough to reach 1,521 and clear the target. Keeping the stake at this minimum lets me make about nine more attempts over the remaining spins.

I need +1203 chips and my bankroll is 297. A 35-chip straight-up bet is the smallest stake that reaches 1,500 on a single hit, which lets me take the most separate shots at the target over the remaining spins.

A single straight-up bet of 36 is the smallest stake whose 35:1 win takes the bankroll past 1,500. Staking the minimum each spin spreads the bankroll across about six independent shots at the target, which beats a few large bets.

I need +1274 chips with 7 spins left, which realistically requires a straight-up hit. Staking 37 is the smallest amount that reaches 1500 if it wins, and it leaves room for about five more attempts.

A 38-chip straight-up win pays 1,330, lifting the bankroll to 1,519 and just past the target. Keeping the stake that small leaves enough chips for several more attempts in the remaining spins.

I need 1,349 more chips in 5 spins, so only a straight-up hit can get there. A 39-chip straight is the smallest stake that reaches 1,500 on a win, and it leaves chips for about two more tries.

A single 40-chip straight-up bet reaches the 1,500 target if it hits (40×36 + 72 = 1,512). It also keeps 72 chips back, enough for another target-reaching straight bet next spin if this one misses.

With 72 chips and three spins left, only single-number bets can realistically reach 1500. Hitting the 42-chip number reaches 1512 at once, and hitting the 30-chip number gives 1080, which still leaves a good chance over the last two spins; this should beat putting everything on one number.

My bankroll is 0 and the maximum total stake is 0, so no bet is legal and the only valid action is to place no bets.

My bankroll is 0 and there are no legal bet IDs, with a max stake of 0, so the only legal action is to place no bet. The target can no longer be reached.
