A dot matrix is a grid filled with dots. The dots of the matrix can be:

• empty (gray)
• full (blue)

A Dot Matrix Test is a sequence represented by dot matrices.

The objective of a dot matrix test is to deduce what the next matrix should be in the sequence.

The program will try to solve any problem of this type that you choose to propose. The only condition which must be met in order to approve any proposed series is that it must be logical and solvable by a human being. In other words, if the series were proposed to a person with a normal IQ (Intelligence Quotient), he or she would be able to solve it.

If you want to know if a series is valid or not, try it on another person.

To enter data in a dot matrix, click on the dots to change their color (from gray to blue and vice versa).
