Reaching +500 needs a long-shot payout, so I spread 20-chip straight-ups over four numbers. One hit pays 700 and reaches the target. Stakes can be adjusted on later spins to cover losses.

Reaching 1500 from 920 needs a large win, so I use straight-up bets sized so a single hit (net +680) reaches the target, while keeping enough bankroll for many more spins.

Need +620 from 880; spreading 23 on each of 8 straight numbers gives a net +620 or more on a hit (8/38 per spin) while risking 184, so about four tries are affordable.

Needing +804 with 17 spins left, seven straight-ups at 28 chips each (196 total) net +812 if any one hits, which reaches 1500 with about 18% chance this spin. That beats grinding outside bets, which almost never accumulate +804.

Reaching 1500 needs +1000 in 16 spins, and a 29-chip straight-up pays 1015, so this is the cheapest stake per chance of reaching the target in one hit. Single straight bets give the best hit probability per chip risked.

Reaching 1500 from 471 needs about +1029, and a 30-chip straight-up win pays 1050, which is just enough. Staking the minimum that reaches the target on a single straight maximizes the number of spins I can afford to try.

Bankroll is 441 and the target is 1500, so only a 35:1 straight-up hit can get there. A 31-chip straight pays 1085, which lifts the bankroll to 1526 and reaches the target. Stakes of 31 let me afford roughly one attempt on each of the 14 remaining spins.

Need +1090 in 13 spins; five straight-ups at 36 each (180 total) net +1116 on any hit, reaching 1500 with about 13% chance per spin, the best available hit rate for a one-spin finish.

Reaching 1500 from 230 needs a single straight-up hit, so I cover four numbers at 40 each: any one hit nets +1280 or more, which gets to 1500. That is the best hit chance (4/38) that stays within the 200 per-spin cap while keeping some bankroll for a later try.

At 70 chips the target needs roughly a 21x gain, so a straight-up hit is the only realistic path. A 41-chip stake is the minimum that reaches 1500 on a win (70 - 41 + 41*36 = 1505), and it keeps 29 chips for later spins.

Reaching 1500 from 29 chips needs a long shot. A full straight-up bet is the one action that can grow the bankroll about 36x in a single spin, and it leaves room for a modest follow-up bet to finish.

Need +456 in 9 spins, so low-variance bets can't get there. Five straight-ups at 15 each give 13% hit chance this spin, and a hit nets +465, enough to reach the 1500 target.

Need +531 in 8 spins; nine straight-ups at 22 each (198 total) net +594 on any hit, which reaches the target, with about 23.7% chance per spin and several retries available.

Needing +729 in 7 spins, I spread 182 chips over 7 straight-ups at 26 each; any hit nets at least 754 and reaches 1500, giving the highest per-spin chance of success (7/38). If it misses, I'll resize the next bets to keep the target reachable.

Need +911 in 6 spins, so I'm covering 6 straight-ups at 31 each. A single hit nets 930 (to 1519) after losing the other five stakes, giving 6/38 odds this spin and keeping some bankroll for later spins.

Reaching 1500 needs about +1097, and a straight-up stake of 32 or more that hits delivers that alone. Putting six straights at 33 each into one spin, then repeating next spin, gives the best chance of at least one hit, roughly 29%.

Reaching 1500 from 205 needs a straight-up hit. Four straights at 41 chips each (164 total) is the widest spread that still reaches 1500 on a single hit (205 - 164 + 41*36 = 1517), giving about 10.5% on this spin.

Reaching 1500 from 41 chips needs a 35:1 hit. Staking everything on a straight now gives 1476 on a win, which leaves two spins to add the last 24 chips, so it has the best chance of reaching the target.

Bankroll is 0 and legal_bet_ids is empty with max_total_stake 0, so no bet is legal; the fallback is no_bet and I place none.

Bankroll is 0 and no bets are legal (max total stake 0), so the only valid action is to place no bets.
