Latest Maine betting news
Most common Maine sign-up bonuses
Here are the three most common sportsbook sign-up bonuses Maine sports bettors can expect from betting sites in 2026.
Second chance bet
With a second chance bet, you’re given two shots at betting glory. Online sportsbooks will insure your first wager up to a specified amount, returning the full stake as bonus bets if you lose. Second chance bets typically range between $100 and $1,000, though some operators have been known to offer up to $5,000 during new state launches and major sporting events.
For example, if Caesars offers a $1,000 Maine sportsbook bonus, you could place a $1,000 wager on the New England Patriots and receive the entire amount back as bonus funds if you lose. Caesars awards its bonus as a single $1,000 bonus bet token, but some other sportsbooks allow you to break it into smaller bets.
'Bet and get' bonuses
A bonus that’s been gaining traction in 2026, the 'bet and get' offer involves new sportsbook users placing a small, initial wager. In return, an online sportsbook will award bonus bets. Typically, sportsbooks will award this bonus regardless of the outcome of your first bet. So, win or lose, you are guaranteed a set amount of bonus bets.
Consider the typical 'bet $5, get $200' offer. After registering and making an eligible deposit, you can place a $5 bet. Following bet placement, the sportsbook will add $200 in bonus bets to your account.
No deposit bonus
Typically reserved for state launches and major events on the sporting calendar, no-deposit bonuses are self-explanatory.
As a new user in a recent legal state, you will receive a specified amount of bonus bets after you create a new sportsbook account. Predictably, you will not need to make a deposit to claim this bonus and will have access to the full amount when the sportsbook begins accepting wagers.
Existing sportsbook users may be able to opt in and claim no-deposit bonuses during March Madness, the days leading up to the Super Bowl, or any time a sportsbook decides to reward its loyal customer base.
