How
to play
This
is an arcadeo.com favorite! You play as the red diamonds, and your
goal is to take over the board by leaping into the spaces adjacent
to your opponent's watery globules. You can move you diamonds in
two ways, firstly you can spawn a new diamond one space away from
any of your diamonds or you can make any piece leap two spaces into
any empty slot.
