Latest Connecticut betting news

Most common Connecticut sign-up bonuses

Connecticut's online legal sports betting sites use the most common sportsbook sign-up bonuses, including first bet offer bets, deposit match bonuses, and no deposit bonuses, all of which have benefits and drawbacks. 

Second chance bet

Second-chance bets promise new online sportsbook users a redemptive shot to hit on their initial wager. Sports betting sites typically refund 100% of the first bet, up to a specified amount, in the form of bonus bets, site credit, or in some cases, withdrawable cash.

With second-chance bets, sports bettors can source optimal wagers with longer odds knowing that if the first wager fails, they'll get a do-over. 

Deposit match

Deposit matches are incredibly popular welcome offers because they offer a tangible and immediate increase to a bettor's bankroll. Sportsbooks offering this bonus will usually match 20%, 50%, or 100% of the initial deposit, up to a specified amount, with site credit.

No deposit bonus

No deposit bonuses appeal to new users looking to test out a sportsbook before sharing their banking information and funding an account. Operators may also use these sportsbook bonuses to target current bettors seeking a small token of appreciation for actively betting on their platform.

For example, when an online sportsbook is preparing to launch in a new region, it may offer potential customers a small bonus bet or site credit just for registering. As this requires no deposit from the user, it qualifies as a no-deposit bonus. 

Some active sportsbooks may give thanks to their existing customer base with small bonus bets here and there, while others will offer bonus wagers during big events like March Madness or the Super Bowl. No deposit bonuses can both motivate new users and engage active bettors.
