Its been more than a week for the 1st round (over a year LOL) and I have not received the prize yet, so the 2nd round might need to wait longer unless they decide to send the prize for both 1st and 2nd round at the same time soon.
Anyway I just noticed that the weekly race is no longer available, seems that the owner decided to take it down after the last round yesterday/earlier today.
Last night I read a discussion in the chat room related to someone/some users who do spam bets in plinko game with tens-hundred dollar base bet which make the user(s) jump to the leaderboard significantly in the last hours.
Someone from the site said in chat that plinko will not contribute to the wager race, I'm not really sure why but I think all games should qualify for the wager race because players are still taking a big risk by playing plinko game even with the lowest risk level.
