At the game number diving, you have lost the way underwater. The only way back is by collecting the numbers and choosing the right answers. To answer a multiplication table question you must swim to the correct answer. When you start the game, you have to choose one or 更多 times tables that you want to practice. If you select multiple tables, you also get 更多 questions and earn 更多 points.
When giving a good answer you get coins. They can also collect coins along the way, via coin treasury box. If you have collected enough coins you can choose another fish. With a 更多 expensive fish you can collect points faster because you get 更多 points per good answer. If you answer a question wrong, this will cost you a part of your life, the same happens when a predator fish hits you.
