Quoted from dtwallace84:Anytime I drain a ball it resets my river class back to 1, unless I get "mystery canyon" "advance to class 6". Can anyone explain this? Thanks
It’s just how the rules are laid out. You have to get to class 6 in one ball or it resets on the next one (unless you get it as a mystery award, as you mentioned). If you get to class 6 in one ball, then it carries over for the rest of the game (and is one of the tasks you need to complete in order to get vacation jackpot)
