The idea of this game is to surround the octopus or octopi with a net so as to protect them from the sharks, whilst at the same time filling the screen with your net. Each time the required amount of the screen has been filled, the higher level wil be selected. As might be expected, every so often one shark, usually one in particular, decides to eat his way through the netting, which does rather undermine the point of the game. Lives are lost from an initial quota of three, either by colliding with a shark or an octopus. This is as far as the game goes, there is nothing left to add, except that it is a success.

Simple though it is, the game is fun and exciting and the uncluttered concept is ideal for any age. Unfortunately, its simplicity could be a disadvantage in as much as it may become boring rather rapidly.
