Welcome to Function Game!

In the Function Game one player thinks of a mathematical rule and the other player tries to guess it.

It's an ideal game for entertaining children and adults on rainy days, dark evenings, or long journeys, at home or on holiday.

A unique feature of this site is that you can play the Function Game on-line against Eliza, our resident game-player.
