Get your words in apple pie order with this fun educational game by Stephen and Andrew Weir
LION'S LAIR is a great game for children who are learning to spell, and up to four can play at once, making it much more fun.
A number of friendly lions have wandered on to your screen, each with a name printed below it. The idea is to arrange the lions in alphabetical order, and as the game becomes more difficult more lions begin to appear.
Each player is allowed up to three mistakes before dropping out of the game, eventually leaving just one player as the winner.
At first just two lions will be on your screen. Using the spacebar, move the two large arrows until they enclose the lion whose name comes alphabetically first.

Gets the players' names
Prints a lion
Plays a tune
Press RETURN to select that one as your choice, and its name will appear at the head of a list shown at the bottom of the screen.
Next, move the arrows to enclose the second lion and press RETURN again. Its name will appear below your previous selection.
If you have chosen correctly, a large tick will appear at the bottom right, otherwise you will be rewarded with a large cross. Two more lions will appear and the game continues until you have completed half a dozen screens or so.
Now you will have three lions to deal with, and eventually - if you are a very good speller - six will appear together.
If you can survive to the end, you can record your name in the high score table among the names of a few feline friends.
The game is thoroughly error-trapped and you can't select the same lion twice. Full instructions are printed at the start, and there is even a little background tune which you can turn on and off by pressing the 1 key.
Arthur Lindon brings an old puzzle up to date
This puzzle was first put forward by the French mathematician Lucas around 100 years ago and presents an intriguing problem to the logically minded.
The game was originally played on a white wooden board using red and blue counters. Marked on the board were nine squares in a line.
The first four are occupied by four blue counters and the last four squares by red ones. Your objective is to swap the positions of the blue counters.
The moves are quite straightforward and there are only three rules to remember:
Blue counters can only move right, while the red counters move left
If the square on the right of a blue counter or left of a red counter is vacant it can slide across
A counter can jump over one of the opposite colour providing there is a space beyond it.
To move a counter press the corresponding letter above it. If you get into a situation where you cannot move, press ESCAPE to try it again.
The number of moves are recorded and at the end you'll be told how many you took. The aim is to take the least number of moves.
My best is 24. Can you beat this?
Improve your key bashing skills with Roland Waddilove's devious typing tutor
This fast and furious arcade shoot-'em-up is actually a typing tutor, and is designed to improve your hand-eye coordination and knowledge of the keyboard.
Unlike other tutors, this one is intended to be both fun and addictive, while teaching you important skills at the same time.
The game places you at the controls of a strategic defence missile silo and it is your task to save the Earth from hordes of marauding alien invaders.
These bug-eyed monsters appear out of hyper space and drop down through the upper stratosphere towards the ground. Little do they know what is in store for them!
Underground are many missile silos, built for just such an invasion. Each has its own control button and pressing it sends a missile to meet the oncoming extra-terrestrials.
The keys to press are printed at the bottom of the screen and change with every wave of invaders.
The first fleet of aliens descend slowly, but later ones move more quickly. You shouldn't experience any problems dispatching the first lot, but the others may prove a little more difficult - it all depends on how fast you can hit the appropriate letters.
If any aliens land they explode leaving a large crater and the blast will reduce your energy - indicated by a horizontal energy meter just above the control keys.
There is a great temptation to cheat and simply hit every key on the keyboard as fast as you can. To prevent this, your energy is reduced slightly every time you hit a wrong key, so accuracy is just as important as speed.
The whole game - apart from the instruction screen - is written in assembly language for speed.
Be careful when entering the listing as a single typing error could make the Electron hang up, or at least print an obscure and meaningless error message.
To be on the safe side, save the program before running it.
