Roulette table

Only reaching 1,500 counts, so I am using the full 200-chip per-spin cap for high variance. Dozen 3 plus Column 3 share four numbers (+400 if one hits), the rest pay +100, and a miss costs 200, so the bankroll survives a run of losses.

I need +400 to reach the target, so I'm betting 100 each on Dozen 1 and Column 1. If the ball lands on an overlap number (1, 4, 7 or 10), the payout reaches 1500 immediately; if only one bet hits, I still gain 100. This takes a high-variance swing, which helps when only reaching the target counts.

Six straight-up bets of 20 each (120 total) are sized so that any single hit takes the bankroll from 900 to exactly 1500. That keeps total wagering low, which limits exposure to the house edge while there are plenty of spins left.

Only reaching 1,500 counts, so I'm chasing a high-variance win. Two straight-up bets of 22 chips each would put me at 1,528 on a hit, and the small stakes leave enough bankroll for many more tries over the remaining spins.

Two straight-up bets of 23 each would take the bankroll to 1518 on a hit, clearing the target in one win. Risking 46 per spin spreads the bankroll across roughly all remaining spins, giving about a 55% chance of reaching 1500.

Bold play toward the target: two straight-ups at 24 each mean a single hit nets 816 and lifts the bankroll to 1,506, above 1,500. This spreads the remaining bankroll over most of the 15 spins, which roughly maximises the chance of reaching the target.

I need +858 with 14 spins left, so I'm using bold play on two straight-up numbers sized so a single hit reaches about 1526. This keeps the per-spin cost low enough to allow many attempts, which gives a better chance of reaching the target than grinding even-money bets with a house edge.

We need about 2.5x our bankroll with 13 spins left, so this spreads the bankroll across the most straight-up chances that can each reach the target. A hit on any of these four 30-chip straights leaves 1550.

Bankroll of 1550 already exceeds the 1500 target and every bet has negative expectation, so skipping protects the goal; skips are not penalised.

My bankroll of 1550 is already above the 1500 target, and success is judged only on the final bankroll. Skipping every remaining spin locks in the target, while any bet has negative expected value and could drop me below it.

My bankroll of 1,550 is already above the 1,500 target, and every roulette bet has negative expected value. Skipping this and the remaining spins locks in success.
