2023 Rugby World Cup

We have set up a small sweepstake amongst our friends (and their friends!) who like rugby to predict the quarterfinals, semi finals, final teams and winner of this year's Rugby World Cup. We charged £10 to enter and the winner doubles their money. A simple idea but easy and fun way to raise £170 for this worthwhile cause.
Can you think of a way you could do something similar? Let us know and we will post it on here.
