BetMGM Bonus Code Offers Double Value for Celtics-Knicks Showdown

The BetMGM bonus code COVERS50 provides two distinct welcome offers depending on your location. In Arizona, Colorado, Washington D.C., Iowa, Illinois, Indiana, Louisiana, Kansas, Kentucky, Massachusetts, Maryland, North Carolina, Ohio, Tennessee, Virginia and Wyoming, new users receive up to $1,500 back in bonus bets if their first wager loses, plus $50 in BetMGM Rewards Points regardless of the outcome. Meanwhile, bettors in Colorado, Michigan, New Jersey, Pennsylvania and West Virginia get $150 in bonus bets when their initial $10 wager wins, along with the same $50 in BetMGM Rewards Points.

For Thursday's Celtics-Knicks clash, imagine backing Boston at -4.5 with a $1,000 first bet in eligible states. If the Celtics fail to cover and you lose, BetMGM returns your full $1,000 stake as bonus bets, distributed as five $200 bonus credits that expire after seven days. Conversely, if you're in New Jersey and place a $10 moneyline bet on the Knicks at +165 odds and they pull off the upset, you'll receive your winnings plus $150 in bonus bets issued as three $50 credits. Both offers require the promo code COVERS50 during registration and a minimum $10 deposit to activate.

BetMGM Rewards Points function as valuable bonus credits that can be redeemed for digital play at BetMGM, converted to MGM Rewards Points for casino and hotel benefits, exchanged for Marriott Bonvoy Points, used to purchase merchandise, or applied toward Gametime vouchers for live events. The bonus bets from either offer must be wagered before any payout becomes available, and BetMGM doesn't return your original stake when using bonus credits.

Tatum's Return Headlines Thursday's Eastern Conference Battle

Thursday's matchup carries significant playoff implications as Boston seeks to lock up the No. 2 seed with just one more victory. The Celtics enter at 54-25 and have won four straight games, with Tatum averaging 21.6 points, 9.8 rebounds and 5.1 assists since returning from his Achilles injury. His emotional return to Madison Square Garden adds compelling narrative to this contest, as he ruptured his Achilles in a playoff game at this venue last season.

New York sits at 51-28 and remains in contention for the No. 2 seed while battling Cleveland for positioning in the 3-4 range. The Knicks have won three consecutive games and five straight at home, led by Jalen Brunson's 26 points per game and Karl-Anthony Towns' double-double averages of 20.1 points and 11.9 rebounds. Both BetMGM welcome offers provide excellent opportunities to wager on this high-stakes Eastern Conference showdown with substantial bonus protection or guaranteed bonus bets.
