This $10 million prize game was made by the free-to-play company Incentive Games and is now available for the 2023 NCAA Championship in the US, which is also known as March Madness.  

There will be a leaderboard and prizes in the new game based on how many points you get for making right predictions. Players in the top 5,000 on the list will get paid.  

With a $100,000 grand prize on the line, the game challenges players to guess how the event will end. 

A player only wins $10m if they correctly guess every match in their pool.  

Anyone in the US (except New Jersey, Virginia, Colorado, and Ohio) can play the Mega March Bracket Challenge for free, as well as people in Mexico and New Zealand.  

John Gordon, CEO and co-founder of Incentive Games, said, "This is yet another slam dunk game for bet365 that will help the brand stand out and get new customers in North America." 

A bet365 representative also said, "Every expert is giving their opinion, but now it's your turn to guess how this Mega March Bracket Challenge will end."

"The buildup to this famous championship is already very exciting, and we hope the chance to win $10 million makes it even more so!" 

Also, BetRivers and PlaySugarHouse just released a new game called Basketball Squares earlier this week. Both of these games went live during March Madness.  

Betr has grown beyond microbetting by launching its new core markets in other places. Fans can now bet on "pre-match and in-play markets for a team to win, a team to win and by how much, and over/under on total points" – just in time for March Madness.

In November, the provider said that they would work together in a similar way for the FIFA World Cup.
