KONG
by Nicholas Sheard
from Sinclair User #10 (January 1983)

[The program as listed is unplayable because of errors in the code.]
[Eg. Line 100 is wrong, as it displays a continuous row of barrels  ]
[which are thus impossible to jump, and the game frequently quits  ]
[when you've neither hit a barrel or fallen down a hole.       JimG]

Kong is a 1K ZX-81 version of the popular arcade game, Donkey Kong. The
idea is to leap over all the objects put before you in the game. That
could include jumping over logs of jumping holes.

If you do not jump and land in a hole the game will finish with error
code 2. The logs start rolling from the right of the screen and you must
use the magic keys - shifted 6 or 7 - to jump the obstacles. Shifted 8
will also allow you to jump right but keys 8 and 5 will allow you only
to move horizontally right and left respectively. 

The program was sent by Nicholas Sheard of Prestbury, Cheshire.

HOT PURSUIT
by S.N. Yogasudram
from Sinclair User #10 (January 1983)

The object of Hot Pursuit for the 16K ZX-81 is to pursue and capture the
moving white [sic] square using the cursor-key-controlled cross. The
game is made more difficult because the block will do its best to avoid
your crusading cross. It will jump to the opposite side of the screen if
you force it onto the black border.

The author, S.N. Yogasudram of Preston, Lancashire, says that the
skilful player can manipulate the block so that it is forced to materi-
alise on top of the cross.

There is a timing system which governs the number of points awarded at
the end of the game. The more time taken to trap the square the fewer
points are awarded.

BRICK BUCKET
by Ken Rylett
from Sinclair User #10 (January 1983)

Brick Bucket for the 16K Spectrum has the gamer catching red bricks in a
bucket. You can move the bucket by pressing "1" to move left and "0" to
move right. The score and number of bricks to have fallen is printed at
the top of the screen. You must catch more than five bricks to reach the
next level of the game, where the bricks fall faster until you catch 10
bricks at high speed.

If you catch five bricks on the first leg, you will go again at the same
speed. If you catch fewer than five the speed of the bricks will drop
until you have gained more experience of the game.

Graphics notes:
Line 1030 - graphic ABC
Line 2060 - inverse graphic 3

The game was sent by Ken Rylett of Burnage, Manchester.

CITY LANDER
by Mark Williams
from Sinclair User #10 (January 1983)

The graphics, sound, and use of colour in City Lander, a version of the
arcade game City Bomber, are amazing for a program which has no prof-
essional programmer behind it.

The game runs on a 16K Spectrum and full instructions are given on the
screen. The aircraft destroys the city so that it can land by creating
fires in the buildings. It travels downward all the time and can only
travel upward once in the game. That means that you must develop skill
quickly.

The game, sent by Mark Williams of Colchester, Essex, also includes a
high score routine which keeps track of the names and scores of the
highest hitting players.

Graphic notes:
Lines 142, 144, 147, 1010, 3515, 3525 - graphic "G"
Lines 1010, 3525 - graphic "GF"
Line 120 - graphic "CB"
Line 141 - graphic "D"

THE FOURIER SERIES
by Clive Bannister
from Sinclair User #10 (January 1983)

A well known result from the Fourier Series is that a square waveform
can be constructed from the infinite sum of the odd harmonics of sine
waves. The Fourier program illustrates this formation as each term is
added and also prints out the range of the summation.

The program, written by Clive Bannister of Wittersham, Kent, will run on
a 2K ZX-81.

GRAND PRIX
by ?
from Sinclair User #10 (January 1983)

Grand Prix is a dodgems game on traditional arcade lines. Your car, an
inverse X, is displayed at the top of the screen and a roadway is
scrolled up towards you. Steer the car with keys 1 and 0 and do your
best to avoid crashing for as many laps as possible.

Two interesting features are a difficulty level and a progressively more
crowded road. If the difficulty level 5 is selected, you will be able to
see several lines ahead - very useful for planning your manoeuvres.
Lower numbers reveal less of the road. In addition, as you speed down
the track, the number of other cars increases.

Lower case letters in the listing signify inverse video. (1K ZX-81)

SAVE THE DAM (Dam Buster)
by Tahir Abbas
from Sinclair User #10 (January 1983)

In Dam Buster for the 16K Spectrum you must save a dam from the aliens
who are intent on breaking it down and flooding a village below. The dam
is on the left of the screen and when the game starts the aliens start
to move towards it from the right. You must stop the aliens by firing
your rockets from a rocket launcher at the base of the dam. You fire the
rocket by pressing the "0" key.

You get one rocket per creature and if you miss the creature knocks a
brick out of the dam. You must hit 10 of the aliens before your village
is saved.

The game was sent by Tahir Abbas of Edinburgh.

PONTOON
by K Hart
from Sinclair User #10 (January 1983)

Blackjack, Twenty-One, Chemin de Fer. Call it what you will, we have an
excellent listing for it. The display features a green baize table, the
four suits in appropriate colours, and a neat pattern on the back of the
cards.

The program has an error trapping function and tells you whether you
have bust or won. You start with a stake of #1,000 and the chance to
break the bank. Thanks to K Hart of Wakefield for a definitive listing.
(48K Spectrum)
