Use bet365 Bonus Code TOPACTION to Claim Best MLB Betting Promo for Opening Day
Sign up now with the bet365 bonus code TOPACTION to lock in one of the top MLB betting promos. New users can choose between two valuable offers—either $150 in bonus bets with a small first wager or first bet insurance up to $1,000. Here's how both bet365 sign-up bonuses work ahead of Thursday’s Mets vs. Astros matchup.
Bet $5, Get $150 in Bonus Bets – Win or Lose
Place an initial bet of $5 or more to unlock $150 in bonus bets, regardless of the outcome. Your first wager must have odds of -500 or longer to qualify.
Let’s say you place a $5 bet on the Mets moneyline (+110) against the Astros at 4:10 p.m. ET on Opening Day:
- If the Mets win, you earn $5.50 in profit, get your $5 stake back, and receive $150 in bonus bets.
- If the Mets lose, you still receive the $150 bonus, even though your wager didn’t hit.
$1,000 First Bet Safety Net
Looking to bet big on Opening Day? With this option, your first wager is insured up to $1,000 in bonus bets if it loses. If your bet wins, you keep the profit and your original stake.
For example, you place a $300 first bet on the Astros moneyline (-130):
- If Houston wins, you collect $230.77 in profit and have your $300 stake returned.
- If Houston loses, you’re refunded $300 in bonus bets, which are valid for seven days.
