How to Use DraftKings Promo Code for Astros vs. Mariners

When setting up your initial qualifying bet for the DraftKings promo code offer, your primary goal should be placing a structured, low-risk $5 wager to unlock the bonus payouts regardless of the match outcome.

• Because the $150 bonus triggers after any qualifying $5 bet, keep your initial real-money wager right at $5 to minimize your out-of-pocket exposure while getting the full bonus value.

• If you want to increase the mathematical likelihood of settling your first bet as a win, look toward a heavy runline favorite, like taking the Astros at +1.5 (-186). While this lowers the net payout on your $5 cash stake, it maximizes your chance of keeping your initial cash deposit intact while unlocking the $150 bonus bets.

• Once your $25 bonus bets drop into your account, keep in mind that DraftKings does not return the bonus bet stake in your winnings. To optimize expected value, consider placing bonus bets on standard lines around -110 or modest plus-money prop bets rather than heavy favorites.
