This game brings out the inner wolf in you. It's very addictive and before long there's nothing you want more than to trap that sheep. The sheep has a good tactical brain on it, for a sheep, so you need to keep to your competitive, carnivorous best if it's not to escape to frolic in the meadows for another day. The game is laid out on a board.

Your four wolves are lined up along the bottom and the sheep at the top. You want to trap the sheep at the top of the board, and the sheep wants to escape past you to the bottom. What makes it hard is that your wolves can only move up the board whereas the wily sheep can move whatever way it wants.

This is a great game if you want to work on your eye for detail. It's much harder than it first seems and to make matters worse you're fighting against the clock. When you click on 'play' you are presented with two images and you must find the five differences between them.

As soon as you see one then click on it to have it ringed. However be careful! If you get it wrong then time is taken off the clock. If you manage to get all five then you can move onto the next level. The problem is that at each new level you'll be given that little less time.

Slider puzzle is made up of 16 squares. In each square but one there is a part of a bigger image. Your task is to move these squares so that you can see the whole image. The longer you take, the less points you get.

The difficulty of the slider puzzle, though, is that you can only move one square at a time, into the solo blank space. The slider puzzle requires real problem solving skills and the ability to see how each separate square's patterns, shapes, colours and lines relate to the other squares. If you like jigsaw puzzles then you'll like this.

In Grab–&–Go your sole job is to get boxes of paper to the office photocopiers. As a job it's probably not the most satisfying (and the work environment leaves a lot to be desired), but as a game there's a surprising sense of achievement in making sure those virtual photocopiers are well stocked.

You use the arrow keys to move, and you can only push one box at a time (for health and safety reasons of course). The fewer moves you make the more points you get. At each level it gets more difficult and it's essential not to push the any boxes in the wrong direction. If you end up unable to move any boxes you need to click on 'reset' to try your hand at it again!

Memory is a lot of fun. Similar to the card game 'pairs' it consists of 16 square tiles laid out in front of you. On the other side of each tile is an image. Your task is to find all the matching pairs. Click on two tiles to reveal the image and if you find a pair the tiles will disappear.

If you don't then they'll be hidden again. You start on 1000 points but with each second that passes you lose one and with each click of the mouse you lose five. If you want to do well then you need to focus and memorise as many of the images as possible – the name of the game is being quick and efficient!
