How to Use DraftKings Promo Code for Athletics vs. Mariners

• Place your initial $5 wager on a high-probability standard market, such as the total runs line or team run lines. Winning the first bet is not required to unlock the bonus, so keeping your cash risk low is a smart way to satisfy the qualifying condition.

• Once you receive your $25 bonus bet blocks, divide them across different markets instead of putting them all on a single event. For instance, you can use one on the Mariners moneyline and another on a total runs prop.

• Remember that DraftKings bonus bets do not return the original stake in your payout. Targeting slightly longer odds or small parlays with bonus funds can help balance the omitted stake while keeping your cash bankroll safe.

• Claim your $50 weekly installments promptly when they unlock on Days 7, 14, and 21. Each token expires 7 days after it hits your account, so set a quick reminder so you do not forfeit any portion of the offer.
