Online sports betting company BetStars have put up the huge cash sum for anyone who correctly predicts the outcome of all 64 World Cup matches – win, lose or draw.
The competition is free with supporters having to first fill in results for the group stages.
They will then have to predict the winners of the knockout matches before going right through to the final.
And to ramp up World Cup fever before the tournament has even started, the company are giving away £3,000 in cash first – as well as four runner up-prizes of an international kit of fans’ choice.
The promotion is being headed up by former England cricketer Freddie Flintoff, who is the face of the campaign.
Details in how to enter to win £3,000 – by answering one easy question – are here.
