What ways can you earn cash other than paying? Also when you fuse to make a hybrid do you lose the initial dinosaurs that help fuse to make a new one? And how do you level up a hybrid? Or superhybrid?
Also in the arena when you level up to a new arena can you still grt dna for dinosaurs in the previous level. For example in lost kingdom u can get dna for trex but in arena level 2 i dnt see it in the section. So do i have to level down to get incubators form arena level 1 to get trex dna?
