Who doesn’t like to get paid? Well, with Bet365’s NCAA basketball early payout offer, you won’t need for the madness to end in order to be cashing in as a winner. Here’s how it works: place a pre-game bet on the moneyline market for any NCAA basketball game up to and including Monday, April 8, 2024. 

For straight bets, if the team you’ve backed gains an 18-point advantage at any stage during the game, Bet365 will pay out your bet in full, regardless of whether the opposition comes back to win the game. For parlays and same-game parlays, if a team you’ve backed on the moneyline market gains an 18-point advantage, this selection will be marked as won within My Bets, with the remaining selections left to run.

Bet365 also offers daily bet boosts and as much as a 70% boost on successful parlay plays.

For newcomers, Bet365 welcomes them with a choice of signup offers. You can take a second chance first bet of up to $2,000, or go for a bet and get of bet $5 and get $150 in bonus bets. Use the code USB365 to access either of these welcome offers
