Roulette table

I need +500 over 20 spins, which requires high-variance bets; a 2:1 dozen at 100 gives +200 per hit with ~31.6% probability, a reasonable balance of variance and drawdown risk.

Need 600 more chips in 15 spins; a 100-chip dozen bet offers 2:1 payout with ~31.6% hit rate, steadily building bankroll while staying within limits.

I need roughly +400 over 10 spins; even-money red at 100 keeps variance manageable while allowing me to raise stakes if behind later.

With 1000 chips and 9 spins to reach 1500, covering two dozens (24 of 38 pockets) gives a ~63% chance of +200 per spin while capping downside at 200, offering strong growth toward the target.

I need roughly +400 within 5 spins; only straight-up bets can bridge that gap, so I take two 35:1 shots within the 200 cap, where a single hit massively clears the 1500 target.

Needing 600+ from the last spin, spreading 198 across 11 straight numbers maximizes success probability: any hit pays 630, reaching 1530; probability ~11/38, the best coverage possible under the 600-profit and 200-cap constraints.
