Action timeline

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching +500 in 20 spins needs straight-up hits. I'm staking two straights at 15 each so one hit lands about 1510, and I'll keep stakes sized so any later hit still reaches 1500.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Needing +530 with a 200 per-spin cap, I spread the stake over 9 straight-ups at 22 each. One hit nets +594 to reach about 1564, with a 9/38 chance on this spin, and I can retry on later spins if it misses.

Model's stated reason

I chose a legal action for this decision.

Model's stated reason

Reaching 1500 needs +728, and two straight-ups at 22 each net +748 on a hit. This gives the best chance of reaching the target over the remaining spins while the bankroll lasts.
