Bitkong also have a weekly reward for their top 10 gamblers but the prize pool isn't fixed it seems like they're based on the site's profit. I tried looking for a clear definition but their bonus page didn't explain much the closest i've found is this post.
Our Leaderboard bonus is some kind of wager contest, where bonus pool generated by total wagered amount. We send this bonus daily, weekly and monthly.
Just checked bitkong's leaderboard and I see that there is up to 99 users who will get the bonus/reward.
Seems that you forgot to scroll down again.
Added to the list anyway.
