Fun fact. We're halfway through and if the qualifier ended today these 12 would be the one's receiving invite to the World Championship
From Cash Jam:
As you can see a 4-6th place in either Cash Jam, Challenges or regular Jams can get you to the top12 as people like Sixfootseven will only receive a spot from one of the categories.
So keep on trying all. If you're in the top50 for any of the categories there's a good chance you could make it!
