New Iowa bettors can claim up to $1,500 in first-bet protection plus $50 in bonus bets from BetMGM using the code COVERS1550, according to Covers.com, ahead of Game 4 of the National League Championship Series between the Milwaukee Brewers and the Los Angeles Dodgers on Thursday, Oct. 15, 2026.
Iowa is one of 15 eligible jurisdictions for the welcome offer, which requires a $10 minimum deposit and a real-money wager to activate. The deadline to claim is Oct. 18, 2026, at 11:59 p.m. ET.
How the BetMGM First Bet Offer Works
According to Covers.com, new users who enter COVERS1550 during registration unlock two offers: a First Bet worth up to $1,500 and an additional $50 in bonus bets. The code is required; there is no other way to activate the welcome package.
Here is the mechanics in plain terms. If your first bet loses, BetMGM refunds your entire stake in bonus bets, up to $1,500. Bets of $50 or more come back as five bonus bets, each worth 20% of the qualifying wager. Bets under $50 return as a single bonus bet.
Example: a $1,500 wager on a Brewers-Dodgers Game 4 market that loses returns five $300 bonus bets. If the wager wins, you keep your winnings and the protection does not apply.
CBS Sports, which covers the same structure, confirms the payout split: wagers of $49 or less return one bonus bet equal to the original stake, while wagers of $50 or more return five tokens worth 20% each. Read the CBS Sports breakdown here.
What Iowa Bettors Need to Know Before Signing Up
Iowa legalized sports betting in 2019, and residents of the Hawkeye State are squarely in the eligible zone for this offer, alongside bettors in Arizona, Colorado, Illinois, Indiana and 10 other states plus Washington, D.C. That makes Game 4 of the NLCS, with a Wisconsin club facing a Los Angeles club, a natural draw for Midwest bettors.
A few conditions from Covers.com worth reading closely:
- A $10 initial deposit and a real-money wager are required to activate the bonus.
- Bonus bets expire after seven days.
- Winning bets are immediately withdrawable, but bonus bets must be wagered before any payout. Only winnings are returned, not the bonus itself.
- Anyone on a self-exclusion list for gambling cannot use BetMGM.
The $50 in bonus bets is awarded on top of the First Bet offer, not in place of it. BetMGM also offers responsible gambling tools for users who need them, and Covers.com directs anyone struggling with problem gaming to those features.
One Analyst's Pick for Brewers vs. Dodgers Game 4
Covers.com analyst Neil Parker recommends Los Angeles Dodgers -1.5 at +140 for Game 4. His case: the Dodgers are running an unsustainably low .264 wOBA and .216 BABIP in the playoffs, which points to a statistical correction at the plate, and starter Tyler Glasnow has been reliable this postseason with a 3.70 xERA and 3.67 xFIP across 26 innings.
The math for a small bettor is simple. A $10 qualifying wager at +140 returns $14 in profit if it hits. If it loses, the COVERS1550 code triggers the bonus-bets refund of up to $1,500.
Where Iowa Sports Fans Can Find More
The NLCS arrives as Iowa sports fans are juggling a busy calendar. The Seahawks vs. Broncos promos for Iowa bettors offer a separate path to more than $2,600 in value, and the Hawkeyes are climbing Big Ten power rankings after their rout of Washington.
College football bettors in the state also have a stake in the playoff picture, with a 24-team College Football Playoff deal reportedly near, a format that could open the door wider for Iowa programs.
Beyond the Welcome Offer
BetMGM users who stick around can earn MGM Rewards Points redeemable for hotel stays, dining and entertainment, according to Covers.com. The sportsbook also runs ongoing odds boosts and bonuses through its app, which bettors should check before placing a Game 4 wager.
