It seems to be working like what you think, tickets are earned within 24 hours only in the raffle day(s). Cant be sure though because I tried to find it out about this raffle on their "docs" page but there is no information about raffle. Anyway, I won 1 prize on the latest raffle with small number of wager on the day of the raffle. Roycilik seems to be forcing himself to wager decent amount on the last raffle day It seems that he is trying to get wager for the VIP transfer reward because he is getting closed to the final day of the deadline (30days after registration). On the other side, he is now also leading in the weekly wagering race.
