Nine patterns will appear in a grid on the screen.
Each pattern will be composed of a set of features, for example, colour, shape, and number.
One of the patterns will differ from the others according to either an individual feature or a combination of features.
You should work out which pattern is the odd one out and click on it.
Subsequently a new problem will be displayed.
Solve as many problems as possible within 3 minutes to gain maximum points.
As your score increases the problems will become increasingly difficult.
