Multiplier hunt is the current popular tournament right now in the forum that involves casino games specifically slot games. In the past, Manager @little_mouse do this multiplier hunt on crash/limbo game which user compete with the highest multiplier they can get without being bust.

This is just my suggestion, you can add a twist on this multiplier hunt contest like you will set a specific multiplier target like x300 and the closest hit +/- will be the winner not the highest so user will thrive to hit a multiplier until it was close enough to the target instead of the typical highest multiplier. 

This contest will make everyone motivated even the unlucky players since they can win even by hitting small multiplier as long as it’s the same target multiplier or close enough.

That's a good point. I've also noticed that most casinos that are present here don't have a link to their ANN in this forum on their website and I think they should have it. Just like how they have their social media handles and other accounts mentioned, they should also have a link to their official ANN in this forum so that people can find them here, that will also help promote the forum and allow members to participate in contests and other stuff that are held on this forum.

Some platforms have their own discussion forums that they promote on their websites, but since they are representing themselves in this forum as well, and we all know that this is by far the largest and the most active cryptocurrency and Bitcoin forum that exists in the internet today, so it shouldn't be a problem for them to have it mentioned at least.
