The fish is lost in the ocean, and you need to help it find its friends. To advance, you must answer questions correctly. Solve the math problems by collecting bubbles and then choose the bubble with the correct answer. Each level has 12 questions to answer, and at the end, you can review any mistakes you made. Learn from these errors to improve. You can also collect coins in bubbles, which can be used to buy new fish in the shop. Watch out for dangers like sharks and electric eels; if you hit them, you lose a life. Enjoy and good luck with your math practice!
