Dodge the man-eating sharks in this frantic race to defuse the bombs - from Stephen and David Burnett

BOMB ALERT The year is 1989, and it is crisis point in the Gulf. Agents from opposing nations are systematically penetrating the waters near your country's stronghold, seeding them with deadly neutron mines.

You, as your country's leading diver and bomb disposal expert - Jacques Custard - have been commissioned (at gunpoint) to keep the harbours free of any exploding items.

Your task is to swim around the shark-infested waters of the harbour, collecting the spanners which have been carelessly dropped by your ham-fisted assistant Penfold.

Once you have collected one you must take it to the bomb to defuse part of the mechanism - but to disable each bomb five separate spanners are needed, and time is ticking steadily away.

The sharks which infest the water are a slight problem, but they can be killed with your trusty harpoon. However, the smell of the blood which this causes will attract other sharks which appear at random positions in the bay.

After you have defused the bomb you are given an extra life, and moved on to another part of the bay, containing faster, much more deadly sharks.

FIBONACCI NIM Strike a light! It's a battle for the last match in Neil Davidson's clever strategy game

FIBONACCI NIM is a game of strategy, based on the popular match puzzle of the same name.

The object of the game is for two players to take turns at removing matches from a pile of arbitrary size. The winner is the one who manages to take the last match.

C% Number of counters
P% Maximum that can be removed
R% Number of couunters removed
n1$ Player one's name
n2$ Player two's name
double() Prints double-height text
set Sets up the title page
box() Draws a bordered box
play Asks for players' details
game Main game loop
delete Removes matches from the pile
Simple it may sound, but this is a very challenging puzzle requiring a great deal of thought. There is only one rule of play - each player may not remove more than double the matches taken by the other player during the previous go.

The reason why the game is called FIBONACCI NIM is that the winning strategy is based on the Fibonacci series - but you will have to get your maths textbook out, because we don't intend to spoil the fun by revealing just what this is.

The game allows two humans to play against one another, or one human versus the computer, or the computer can even play itself - type 2, 1 or 0 respectively at the "Number of players?" prompt.

The computer is, of course, well aware of the Fibonacci series, and is therefore very hard to beat, but it can be done.
