Or else this competiton is screwed. How have i been picking S-League games?
Rules are rules. You set them!
You have been able to pick S-League games because you had 5 bets a day from 12am to 12am. However, this challenge specifically said it was over 12pm today. So you had bets up until 12pm today according to the rules.
Therefore if you want to renege and if you win, the result won't count and this challenge will be null and void.
