From the projects page (https://sourceforge.net/projects/jooleem/):
Jooleem is a simple yet extremely addictive puzzle game. The best way
to kill 10 minutes. There is only one rule: click on four marbles of
the same color that form a rectangle. Time is constantly running out,
but you can earn time by forming rectangles.
