Marathon is a game of mental arithmetic that should prove educational for the 8-14 age group. It can be played in pairs; alternatively one player competes for time against the computer.

The top of the screen depicts two marathon runners. Each time you answer a question correctly your man moves one step towards the winning post on the right. The centre of the screen shows two 3x3 grids, each grid square showing a possible answer. When a question flashes up, use the joystick to move the cursor on your grid to the square showing the correct answer: the first person to hit the Fire button with the cursor in the right place wins, and his man moves towards the winning post.

Four skill levels (i.e. time allowed) can be selected and the type of questions can be varied between addition, subtraction, multiplication, and so on. This game might be simple; but it is very well presented, and holds a child's interest. A good example for this type of educational program.
