How it works
Each round gives you ten problems, and every correct answer scores one point. Games 1 to 4 are addition, subtraction, multiplication and division with a top number you choose yourself, which is useful for practising a single times table. Games 5 to 8 cover the same four operations with random numbers. With the timer on, you have 12 or 24 seconds per answer.
NTSC or PAL?
NTSC was the TV standard in North America and PAL was used in most of Europe. The two cartridges contain the same maths problems, but the picture was prepared for different televisions, so colours and screen timing can differ slightly. If one version looks wrong on your screen, try the other.
