Here you can configure application settings: 


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.

Which dot was not on the same imagined line?

(0 = all dots were on the same line)
