Math Charge Multiplication
Each round plays out as a quick-fire maths drill disguised as a naval duel. You read a multiplication problem, enter the answer as a depth using the on-screen keypad or keyboard, then launch a charge with the spacebar or a click. Movement is handled with the arrow or AD keys, and you clear mistakes with the X key before your health runs out. It runs in the browser on desktop, in landscape, with no installation needed.
