You're playing this challenging game against the computer.
Your quick
reaction is required to bounce the fast approaching ball back
to the wall.
You're not at zero gravity here; the effects of gravity
in this handball court
are unusual and will add levels of complexity to this game.
Computers are not perfect beings, so you have a chance to beat
the machines
at this game. The beginner level games allow the
unskilled
and those weak
at heart an opportunity for self improvement.
However,
the advanced levels
will challenge your hand-eye coordination
skills to their limits.
