I didn't find anything about tournaments on the site, just about competitions which are pretty much self explanatory I think.
Be in the top 10 for the highest amounts wagered hourly/daily/weekly and you get rewarded. Same for getting the biggest multipliers on casino games and biggest wins, there is a list for everything.
Self-explanatory but not complete. For example, it doesn't say that the prize you win is a bonus, which needs wagering. It was 70x when I was last active, not sure about it now, if I check my last messages, it doesn't seem to really say.
Then again if you check now it says prize is "Main Wallet" so does this mean it's no longer a bonus? I guess so, but if you're a new player, would you know what Main wallet and Bonus wallet means?
And it doesn't list a prize for Weekly Biggest Win or Weekly Biggest Multiplier anymore.
So I'm kinda just guessing what these are, I wouldn't say everything is self explanatory. I could be wrong, but this is what I mean, one shouldn't need to search high and low for that info.
And see questions from @bitbollo. There's no information to find about Jack token...
