In this game you use the keyboard or a Kempston joystick to control a large snake called Slippery Sid. Sid must eat all the frogs within a walled garden without hitting the walls or any of the poisonous toads that appear every time he swallows a frog.
As Sid eats the frogs he gets longer and steering him around becomes more difficult - he will die if he attempts to eat himself!
Magic mushrooms grow in the garden. If Sid eats one of these, he may swallow one poisonous toad. As Sid clears the garden of frogs, he finds himself in another garden with more walls and a larger number of frogs.
The instructions supplied are adequate and the program LOADed every time. You are given five skill levels (the speed at which Sid moves) and highest score is recorded, but not the player's name. On entering the fourth garden, you get an extra life (you start with three).
The review copy seemed to have a bug that caused Sid to randomly change direction at the most inconvenient times. Even with this added handicap Slippery Sid is a highly addictive and enjoyable game.
It is simple in operation and the increasing difficulty level from garden to garden is well balanced to give the beginner and expert alike a good run for their money.
