A single hit must net at least 500, and ten straight-up bets of 20 are the widest cover that still does that within the stake cap. If one hits, the target is reached immediately and later spins can be skipped.
Model's stated reason
Even-money and dozen bets cannot reach 1500 in three spins under the stake caps, so I cover eight numbers at 25 each; any hit nets exactly 700 and the target.
Model's stated reason
Last spin and 900 short, so only straight-ups can hit the target. Six numbers at 30 each is the widest cover that still nets exactly 1500 on any one hit.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
