Thursday Night Football pits the Lions vs. Bills at Highmark Stadium tonight — the first regular-season game inside Buffalo's new building — at 8:15 p.m. ET on Prime Video. The line has moved a long way off its Buffalo -3 open. BetMGM now prices Buffalo around -5.5 (-110) and -245 on the moneyline, with Detroit at +5.5 (-110) and +205. The total has climbed to 54.5. Odds as of Thursday afternoon and subject to change. Two weeks into a season nobody has figured out yet, a safety net on your opening ticket with this NFL betting promo makes a short-week primetime game far easier to have a bet on.
You pick the stake, and BetMGM bonus code TOPACTION refunds you in bonus bets when the bet misses. That refund tops every rival welcome offer on the market this September, and it lands within 24 hours of your first bet settling.

Which BetMGM bonus code should you use tonight?
BetMGM runs three separate welcome offers, and you can only claim one. TOPACTION unlocks the biggest of the three, but it is not automatically the right one for every bankroll.
| Offer | What you get | Best for |
|---|---|---|
| First Bet Offer (TOPACTION) | Up to $1,500 back in bonus bets if your first bet loses | Anyone staking $50 or more on one game |
| Bet $10, Get $150 | $150 in bonus bets if your first $10 bet wins | Small stakes and short favorites |
| No Sweat Bets | Up to $1,000 in no-sweat tokens across 10 days | Bettors who prefer to spread risk over a full week |
On a coin-flip primetime line like Lions vs. Bills, the First Bet Offer is the one to take: the $150 version only pays if you win, and the 10-day token offer caps out $500 lower.
Is BetMGM bonus code TOPACTION available in your state?
The $1,500 First Bet Offer is live in AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, NC, OH, TN, VA and WY. New customers in MI, NJ, PA and WV get a different BetMGM welcome offer, so check the promo page in your state before you deposit. BetMGM takes bets in Nevada, but registration has to be completed in person, and welcome offers are currently paused in New York. You need to be physically inside an eligible state when you place the bet, not a resident of it.
Why use the BetMGM Bonus Code TOPACTION on Lions vs. Bills?
Week 1 punished anyone who trusted the favorites, and with so little to go on, we are expecting more of the same in Week 2. Protect your wager with the BetMGM bonus code TOPACTION.
- Cardinals 26, Chargers 14: Arizona won outright as an 8.5-point road underdog.
- Giants 28, Cowboys 20: New York upset Dallas on Sunday Night Football.
- Jets 23, Titans 10: Gang Green won on the road as underdogs.
- Lions 31, Saints 30 (OT): Detroit laid 7.5 points, blew a 21-0 lead, and missed the cover.
Buffalo passed its own test, beating Houston 36-31 as a 1.5-point road favorite. One of Thursday's teams covered last week and most of the rest did not, which tells you how little separates the market from the scoreboard right now.
The spread trade: back Detroit +5.5 (-110). Jahmyr Gibbs ripped off 156 rushing yards on Sunday, Buffalo allowed the fifth-most rushing yards per game last season, and the Lions travel on a short week as healthy underdogs. The move from -3 to -5.5 hands you two extra points on a game between two 1-0 teams that scored 67 combined points in Week 1, and 64% of spread tickets are already on Detroit. The caveat: Detroit is down Kerby Joseph (knee) and Brian Branch (Achilles) in a secondary that just conceded 410 passing yards, which is exactly why a refunded first bet is the sensible way to play it.
Now the part that matters. Say you stake $1,500 on that spread and Buffalo wins by seven. With BetMGM bonus code TOPACTION, five $300 bonus bets arrive Friday morning, and you go again on Sunday Night Football between the Colts vs. Chiefs (8:20 p.m. ET, NBC), then Giants at Rams on Monday night (8:15 p.m. ET, ESPN).
One Thursday miss still leaves you three primetime swings. Track the numbers on our NFL odds page and check late scratches on the NFL injuries feed first. Full terms are broken down on our BetMGM bonus code page and in our BetMGM Sportsbook review.
Which sportsbook runs the best first-bet reset offer?
Rival books run similar resets, though none match this BetMGM promo code for sheer size.
| Sportsbook | Welcome offer | Max refund | Steps to claim |
|---|---|---|---|
| BetMGM | First bet back in bonus bets | $1,500 | One bet |
| bet365 | First Bet Safety Net | $1,000 | One bet |
| Fanatics | No-sweat bets over 10 days | $1,000 | 10 bets |
| theScore Bet | First bet back in bonus bets | $1,000 | One bet |
The BetMGM bonus code TOPACTION takes the biscuit in all four categories here:
- Biggest refund: $1,500 beats every rival safety net by at least $500.
- Fastest path: one qualifying bet finishes the job, while Fanatics asks for 10 days.
- Widest choice: spreads, totals, moneylines and parlays all qualify.
- Best for one big game: a single Thursday ticket unlocks the full amount.
The trade-off worth knowing: BetMGM's refund is only triggered by a losing bet, so a winning first bet returns cash and nothing else. DraftKings pays its $200 either way, which makes it the better pick if you only plan to stake $5.
