Bet $5, Get $300 If It Wins
DraftKings promo code delivers $300 bonus for Mariners vs Padres
New DraftKings customers can claim $300 in bonus bets without needing a DraftKings promo code for Thursday's Mariners vs Padres game. The offer requires a minimum $5 wager on any market with odds of -500 or better, and if your bet wins, you receive twelve $25 bonus bets totaling $300. This promotion must be activated by selecting the token before placing your qualifying wager.
For example, if you bet $5 on the Padres to win at -120 odds and they complete the sweep, you would receive your original winnings plus the $300 in bonus bets. However, if Seattle's Luis Castillo bounces back from his rough previous outing and the Mariners avoid the sweep, you would only lose your $5 stake without receiving the bonus bets. The bonus bets expire seven days after issuance and cannot be withdrawn, though any winnings from bonus bet wagers are yours to keep.
Key terms include:
- One offer per new customer
- Minimum -500 odds requirement
- Token must be selected before placing bet
- $5 bet must settle by May 3, 2026
- Bonus bets issued as twelve $25 credits
- Available in eligible jurisdictions for users 21+ (18+ in select states)

SEA (-118): Right-hander Luis Castillo has had the Padres’ number over the years, limiting San Diego hitters to a .206 batting average and .521 OPS. With the Mariners’ offense set to face the sputtering Walker Buehler, expect Seattle to prevail at Petco.
