I need +500 in 20 spins and only reaching the target counts, so I'm staking 16 on each of three numbers. Any single hit nets about +528 and reaches 1500, while keeping each spin's cost low so the bankroll lasts many attempts.

The goal is to reach 1,500 chips from 952, which needs about 548 more. A 16-chip straight-up bet pays 35:1 and would take me to 1,512 in one win, while keeping losses small enough to try over many spins, giving roughly a 40% chance across the remaining 19 spins.

Nine straight-up bets of 21 chips each (189 total) give roughly a 23.7% chance this spin of netting +567, which would reach 1503 and hit the target in one spin. Near-bold play keeps total chips exposed to the house edge low, which suits a target-only objective in a subfair game.

Every bet carries the same house edge and only reaching 1,500 counts, so I use high-payout straight-ups sized so one hit just clears the target (747 - 189 + 972 = 1530). This gives a 7/38 chance of finishing this spin while limiting total chips exposed to the edge.

I bet the minimum straight-up stake whose 35:1 win reaches the target: 558 + 35×27 = 1503. That keeps enough bankroll for about one such attempt on each of the 16 remaining spins, which roughly maximises the chance of hitting 1500.

Bold-play approach: I am staking the smallest single straight-up bet whose 35:1 win takes the bankroll over 1500 (531+980=1511). This keeps enough chips for many more attempts across the remaining spins.

I need +997 in 14 spins, so I am making the smallest straight-up bet whose 35:1 win reaches the 1,500 target (503 - 29 + 1,044 = 1,518). This keeps enough chips to repeat similar shots on later spins.
