In the game, players can predict how countries will do at the 2022 FIFA World Cup in Qatar, earning points for every correct pick.

A £1m jackpot is available for correctly predicting the entire tournament, with the top-scoring user set to claim £100,000. The top 10,000 users will share prizes worth £250,000.

“We are delighted with the look and feel of this game - it is the best-looking title we have produced to date,” said Incentive Games CEO and Co-Founder John Gordon.

“Going live across so many countries with the world’s favourite bookmaker is another watershed moment for us.

“If this is not the game with the most free-to-play entries for the World Cup, I will eat my kilt.”

The 2022 World Cup begins this Sunday as hosts Qatar take on Ecuador in Group A. The competition will run until December 18.

A bet365 Spokesperson said: “Think you have what it takes to predict an entire World Cup? If so, there’s a £1m jackpot waiting for you! 

“At bet365 we’re delighted to deliver this free-to-play game to our customers ahead of the tournament and look forward to watching those predictions unfold.”

Last week, Sorare partnered with 18 national football teams to launch Sorare: Global Cup ’22.

The new free-to-play game comes ahead of the World Cup in Qatar and has such national teams as Germany, Argentina and Spain featured – with most of them signing long-term deals that reach beyond the finale of the tournament.
