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
I agree. I am voting for the first option. If there is no accurate goal prediction, the prize is transferred to the next round.
worldofcoin's and sam00's ideas are also good.
