Regarding winners choice, we are open to your suggestions

in my other prediction-games we have to following rule:
if no one has the exact score, then the price will be on top for the next game (called 'jackpot')
other option:
next game not 3 winners, but 6 winners with correct score
And the jackpot will be divided between top 2 next game's match predictors 50/50. Or who predicted the score first could also be given 100% of the jackpot.
