Three symbols appear in the centre of the screen as a vertical column and the player has to move them to one of 4 sets of 3 columns by pressing up, down, left or right.

The faster you make decisions the longer you will last, but the more mistakes you will make. The author's personal best score is 9600, can you beat that? Inspired by a video game popular in Belgian bars. Features a high score table and redefinable keys. Joysticks and Zon-X sound supported.

Game-Pac is a compilation of two games and a dice rolling program. Greed is a dice game played against an AI opponent. The objective is to get the highest score by rolling two dice and adding the result of each roll. The game is played in ten rounds and when the player chooses to stop the score is added to the one of previous rounds. Rolling the starting value a second time leads to a crap out and all points of the round will be lost. Brain Teaser is a puzzle game similar to the board game Lights Out. The player is presented with the numbers 1 to 9 shown on a 3 by 3 grid. Numbers are either normal or inverse and the goal is to get an inverse 5 and all others as normal. The player can choose to flip any number but then also all adjacent numbers will be flipped. Super Dice is a program that simulates dice rolls. The player can roll up to five six-sided dice or one four-, eight-, ten-, twelve- or twenty-sided die.

ZX Compendium is a collection of six games and programs that contains: Alien Intruder: During a long space voyage to Earth, you have been woken from cryogenic suspension to find, to your horror, the rest of the crew devoured by an alien lifeform. To prevent yourself being the next item on the menu you have decided to collect enough essential supplies before escaping in a shuttle. The game is a text adventure with some graphics where the screen is split into two. The top half shows a map of one of the three levels of the ship with your location and the aliens if on the same level as you, a map showing your immediate surrounding area and any exits, and finally the supplies you need to collect which are oxygen, cells, water and food. The bottom half of the screen has text describing your current location and you type in commands with the keyboard to interact with each location. If you enter a location with the alien then you die but if the alien enters your location then you need to deal with the situation. Wumpus Adventure: A text adventure that allows one to four players to move around an area hunting for creatures called a Wumpus to kill. Before you start the hunt you have a number of options and they are, choice of caverns (Novice, Random Cave Pattern and Professional Hunter), number of players, and if you hunt to the death or kill a certain amount of Wumpus. The actual game sees text on the screen describing each location of a player and the current player types in commands to interact with their surroundings. Each player gets one move before the next player has a turn. The players are armed with five arrows but more can be collected, and as well as Wumpus there are other creatures like Goblins and giant serpents that need to be dealt with. Numerology: A program that allows you to enter your name and birth date to receive a reading about your personality and find out your lucky number, colour and day of the week. Hangman: Based on the pen and paper game, you can compete against the computer or another person as you try to guess a word without being hanged. A word is generated and you have to select a letter at a time to try to make the word. If you guess a correct letter then it appears in the word but get one wrong and a man being hanged on a scaffold starts to appear. The computer has two levels (1-2) to choose from. Hieroglyphics: You have to decipher 39 Hieroglyphics by placing a letter or a vowel combination under the correct symbol and the computer will give you a word to help you decipher them. You must be careful in your guesses though because each wrong guess sees trapped explorer Wullie Makeit's tomb slowly fill with sand. Movie Mogul: A management game where with a limited budget you have to buy a script and attempt to make a movie and make a profit with it. After buying a script you decide which type of movie to make as well as hiring a director, actor and actress. You decide on each day of filming how much money to spend on various options watching your budget levels decrease. Once you have completed filming you are given a final score as a profit or loss for the finished movie.

3D space shooter

Maze Death Race is a Rally-X variant. The player controls a car and has to drive around a maze and collect a certain number of flags to complete a level. At the same time other cars chase the player's car and attempt to hit it. The number of cars are user defined in the ZX81 version and pre-defined in the ZX Spectrum version. In addition to chaser cars there are various traps on the roads that the player has to avoid hitting such as rocks, oil and ice. Unlike the original arcade game, in this version the player cannot use a smokescreen to confuse the chasers. Both versions allow the player to choose the speed of the AI cars. In the ZX81 version, it is also possible to choose if the car should have momentum while in the Spectrum version this is always the case.

Place the arrow, change the direction of the car, and pass all the flags to clear the game. If the car goes off-screen or hits a rock, it is a failure. If the car hits a wall, it will flip, but the wall will disappear.
