A single dot (circle) will appear briefly on the screen.

Your task is to find a dot that will NOT be within the same imagined (vizualized) line (direction) and enter the order of appearance (ordinal number) of this dot on the screen.

There are two possible cases:

1. only one of the dots displayed will NOT be within the same imagined line. In this case, enter the ordinal number (1,2,3 ..) of this dot that is NOT in the same vizualized line.
2. all points are within the same imagined line. In that case, enter 0 as a correct solution.

At the end you will be informed about your results.

A single dot (circle) will appear briefly on the screen.

ALL these dots ARE WITHIN the SAME imagined (vizualized) line (direction).

Your task is to find a dot that will have DIFFERENT DISTANCE from the previous and next dots within the same imagined line and enter the order of appearance (ordinal number) of this dot on the screen.

There are two possible cases:

1. only one of the dots displayed within the imaginary line will NOT be displayed at an equal distance in relation to the previous and the next dot. It will be displayed a little closer or a bit further than the other dots. In this case, you should enter the ordinal number (1,2,3 ..) of this dot as the correct solution.
2. all dots are located at an equal distance within the same imaginary (vizualized) line. In that case, enter 0 as a correct solution.

At the end you will be informed about your results.
