Did not look up the script, but you want something like reward cash?
So post this code on your function when the minigame ends and the winner is announced.

pawn Код:

GivePlayerMoney(winnerid,random(100000));

It will give the winner reward as cash.
Thank you.
PS: this is an example, you need to use your head a bit to make it work.
