Knockin

The object of Knockin is to collect as many coins to reach the points to win
before your opponents do. You want to be careful not to fall off the playing
field or you lose points. Of course, you can always knock your opponents off
the field to make them lose points but be careful as they can do the same to
you. Up to four people can play on the same computer or up to eight people can
play over a network or the internet.The point values can be set at the start
of a round but the defaults are three points per coin, lose two points if you
fall off the playing field. The game ends when one player reaches thirty
points.
