I've tried it, only got a 20x multiplier, ah I'm embarrassed to post it, there are 5 days left, I'll try again, I'm curious about other slot games, hopefully luck will be on my side, so I can be one of the winners in the contest too

I haven't met an opponent who is the same as me yet
Too bad your entry is actually not eligible for the contest since your bet amount is under the minimum bet as required for the contest.
Didn't you notice that the min bet is $0.2 so you submitted an entry with min bet 2000IDR which worth $0.12 only at the current rate?
Better to change your entry before the contest end as it seems you are the only participants and you have big chance to win the 1st reward.
It will be sad if you are the only participant but you do not win it because of your bet is below the requirement.
