1Check is a freeware strategy game where your goal is to remove as many
balls as possible from the starting location.

The game consists of a 8×8 squares playfield, whereby the outer two rings are
filled with those balls and the inner 2 rings are empty.

Now you have to diagonal jump one ball over another ball into the free space.
Once that happens, one ball is counted as removed, the place where it is now
is occupied and the place where it was is now part of the empty zone.

The game just consists of one level, but the goal is to increase the number of
balls you remove and ultimately remove 47 out of the 48 (the maximum).
