This is just my speculation, but there are perhaps some number of shark paths, say a 100 or so different routes the shark will take, and u just randomly get one. On the other hand, as mentioned, I saw the shark never went top side at least once. I think our choices must matter to some extent because going all middle row never works after 10000 tries. does the spin determine the outcome of the bonus round, or do our choices determine the outcome? If a developer or anyone is able to comment.
