Sportsbooks Push MNF Sign‑Up Promos

Week 4’s Monday Night Football doubleheader pits the New York Jets at the Miami Dolphins and the Cincinnati Bengals at the Denver Broncos, with the Dolphins about 2.5-point favorites and the Broncos about 7.5-point favorites and both games listed around a 44.5 total. Sportsbooks are rolling heavy sign-up promos to capitalize on the matchups, with Bet365 prominently advertising welcome codes SILIVE and SYRACUSE that promise roughly $200 in bonus bets after a $5 qualifying wager (SYRACUSE also promoted as a first-bet safety net up to $1,000); those Bet365 offers are being promoted across about 15 legal betting states and generally carry seven-day expirations. Bet365’s bonus bets can generally be used on spreads, totals, same-game parlays, player props and live markets, and the operator is also promoting state-specific codes such as NYPBET. Competing offers include DraftKings’ $200 bonus bets plus an NFL Sunday Ticket discount, FanDuel’s up-to-$300 first-bet-style promo, and BetMGM’s casino-code ALCOM offering a $25 sign-up casino bonus and deposit-match incentives for casino play. Bettors are urged to compare promos, confirm state eligibility, read terms for wagering windows and use restrictions, and use apps’ responsible-gambling tools before staking funds.
