How to Use DraftKings Promo Code for Cubs vs. Mariners

• Consider placing a small $5 entry wager on the Chicago Cubs (-102) or Seattle Mariners (-105) moneyline. A straight moneyline wager provides a straightforward way to meet the minimum qualifying requirement to claim your $150 in bonus bets.

• If you prefer spread markets, looking at Seattle +1.5 (-189) offers a protective edge on paper, meeting the qualifying wager rule while minimizing initial risk.

• Splitting your unlocked bonus tokens into smaller $25 bets across player props (such as strikeout over/unders or total bases) allows you to spread out risk across multiple outcomes rather than committing everything to one game.

• Always set a firm daily budget before placing bets, track your activity, and never wager more money than you can comfortably afford to lose.
