Sports Interaction MLB Promos

Sports Interaction is one of the better online sports betting sites in Canada. Sports Interaction has you covered whether you're looking for the meat and potatoes MLB bets or hard-to-find baseball betting markets like those from Mexico and Japan. The Sports Interaction app is beginner friendly and features a strong selection of baseball props to choose from.

Welcome Promo: Sports Interaction is currently offering new customers a 125% sign-up bonus for deposits up to $250. There's a 6x rollover on your deposit + bonus. In other words, a $250 deposit will earn you a $312.50 bonus and you'll need to bet $3,375 (6x $562.50) before withdrawing funds.
Parlay Boosts: Sport Interaction often offers a "200% parlay boost." The title is a little misleading because you only earn 200% if your parlay has 30 legs (which is obviously rare), but the more legs, the higher the boost. For example, a 2-leg parlay is boosted by 2% during this promotion while a 5-leg parlay is boosted by 12%.

A 125% bonus is generous when compared to other MLB betting sites.
Extra boosts on parlays throughout the season add up and help your bankroll.

BET99 offers fair odds for MLB games and a robust list of props for batters and pitchers that can be combined into large same game parlays (if that's your thing).

Welcome Promo: BET99's "First Bet Encore" promo offers up to $800 in bonus bets if your first wager loses. For instance, if you sign up and bet $800 on the Blue Jays and they lose, you will receive back four $200 bonus bet tokens (totalling $800).

why you'll want to claim BET99 MLB Promos:

A maximum match of $800 is a great deal if your budget allows it.
Easy access. Those with smaller budgets of $20 can also get a match.
The MLB live betting from BET99 is fantastic and that alone makes BET99 worth downloading.

TonyBet MLB Promos

Not only does TonyBet offer a full market of MLB games, but it's also one of the few MLB betting sites that allows you to bet on AA and AAA Minor League games as well. That's right, the Springfield RoughRiders and San Antonio Missions are fair game at TonyBet. Both MLB and Minor League games are equipped with live betting capabilities too.

Welcome Promo: You can earn up to $350 in free bets with a minimum initial deposit of $15. The free bet reward will match the size of your deposit up to $350 and expires after 14 days. Keep in mind there's a 5x rollover requirement before withdrawal.
Combo Boosts: TonyBet offers boosts on its "combo bets" which are what other sports betting sites refer to as parlays with 3+ legs. The larger your MLB parlay, the more generous the boost up to 100% which requires a 20-leg parlay.

Odds Shark FinCertified Trust Factors

Image
User Experience: We are looking for sportsbook promos that make the betting process seamless. If we have a hunch on a game, we want the odds for that game at our fingertips. Easy-to-access Bet Slips, intuitive Parlay Features, and a detailed Betting History, are just a few of the user experience criteria our experts require from a top sports betting app.
Image
Bonus Availability: We look for sportsbooks that offer real value in their customer deals. Not some snazzy marketing lingo, but real dollars available for you to collect. From killer welcome bonuses and promo codes with realistic conditions, to lucrative everyday customer offers, Bet Boosts, rebates, and VIP programs. Sportsbooks must offer something we can understand and can reasonably collect upon, or we won't recommend them to you.
Image
Payment Process: We all want to be able to fully realize our winnings and take our money home. Too many sportsbooks make it so difficult to withdraw your funds, that you are forced to bet again, seemingly indefinitely. At Odds Shark, we only recommend betting apps that our experts are comfortable holding their own bankroll. The best sportsbooks in the United States offer a variety of reliable deposit methods with reasonable payout speeds, so that you aren't that friend who can't buy dinner because "all my money is in my betting account".
Image
Sport Odds Variety: We champion sites that provide extensive odds across a huge range of global sports. Sportsbooks must prove they are ready to promote big events properly. It isn't going to matter whether a betting site has Korean Baseball odds, if they can't get the Super Bowl right, but we know the way those popular betting markets are juiced. Every now and then, our Odds Shark handicappers have a gut-feeling on a European Handball match at 5am on a Wednesday. We want a sportsbook that lets us ride that out with them.
Image
Safety & Security: Odds Shark takes player safety very seriously. We only recommend betting sites that match our high degree of safety and security standards. That means a site must operate 256-bit SSL or TLS encryption as standard. They also need to provide fair, transparent Terms & Conditions for all players.
