BetMGM Bonus Code Offers Double Value for Padres Showdown
The BetMGM bonus code COVERS50 provides two distinct welcome offers depending on your location. In most states where BetMGM operates, new users receive First Bet protection up to $1,500 plus $50 BetMGM Rewards Points instantly upon registration. If your initial wager on the Mariners vs. Padres game loses, you'll receive your entire stake back in bonus bets, with larger wagers split into five equal bonus credits.
Players in Colorado, Michigan, New Jersey, Pennsylvania and West Virginia enjoy a different structure with the same bonus code. These users need only place a $10 minimum wager on Thursday's game, and if it wins, they'll receive $150 in bonus bets distributed as three $50 credits. Regardless of the outcome, all users receive $50 in BetMGM Rewards Points immediately.
BetMGM Rewards Points offer significant value beyond sports betting. These points can be redeemed for bonus credits for digital play at BetMGM, converted to MGM Rewards Points for casino experiences, transformed into Marriott Bonvoy Points for travel, exchanged for merchandise, or used for Gametime Vouchers. For example, if you bet $100 on Walker Buehler to outpitch Luis Castillo and win, you'd collect your winnings plus the bonus structure. If you lose that same $100 wager in eligible states, you'd receive $100 in bonus bets to continue wagering on the series.
What our experts say about Mariners vs. Padres
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.
