There are more rides than Amusement Park 4000, and AI and strategy is more sophisticated than the 16K Spectrum version of Fun Park. You've never seen a ZX81 game that looks and plays like this.

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.

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.

Jungle Maths is an educational game for multiple sytstems. The player must travel through a jungle to reach their home base and safety. To do this, they must correctly answer 10 math questions. A map tracks the player's progress. If the player answers incorrectly, they could fall in a pit, sink into quicksand, or have other animated maladies befall them. Five incorrect answers, and it's game over. Options include numbers from 10 to 1000, subtraction or addition, negative numbers, and time to answer the questions.

You control a base on the bottom of the screen moving left or right, and you have to blast or avoid falling meteors with your laser over five waves. As you avoid or blast the meteors, you also have a panic button which removes all meteors on the screen but using this reduces your bonus. A wave ends when your base is hit and you move to the next wave but with the meteors falling faster. Before you start the game, you can select three levels of difficulty, Slow, Fast and Expert.

Munchees is a Pac-Man clone where you must move around a maze to clear it by eating all the dots. As you eat the dots you have to avoid ghosts and if you touch one then you lose one of three lives. There are power-pills that can be eaten and these allow you to eat the ghosts for a short time. You have a choice of how many ghosts on the maze (1-4).

QS Scramble is a clone of the arcade game Scramble. It's a side-scrolling shooter where the player controls a space craft flying over the surface of an alien planet. Movement is limited to moving up and down and there are two weapons to attack with: forward going missiles and bombs that are dropped onto ground targets. Five missiles can be fired at a time and three bombs can be dropped at a time. Targets include aliens that swoop down from above and rockets that launch from the ground. On the ground there are also fuel dumps. The game goes on until the player has lost all three lives or the fuel runs out.

Namtir Raiders is a fixed screen shoot 'em up. The objective is simply to shoot down as many enemy raiders as possible and save the earth. There are four waves of enemies and each wave has a different kind of enemy. The movement of the ship is a bit different from other shoot 'em ups. Rather than having keys for up, down, left and right, they here lead to diagonal moves (for example up and left, down and right). The player has five lives and earns more when all four waves have been completed. Once they have the game starts over with the first wave. A difficulty level between one and three can be chosen before the game begins. The higher levels run at a higher pace.

QS Asteroids is a fairly basic conversion of the original arcade game. The action starts immediately after loading (no title or options screens here) and players finds themselves in a space ship in the middle of the screen with numerous asteroids passing by. To control the ship, two keys are used for rotating it, one for shooting and another for thrusting it forward. Shooting can be done in eight directions. On an unmodified ZX81, the ship is represented by a number which changes with rotation (For example 0 means it's pointing up, while 4 is down) and the asteroids are o's, while users with a QS CHRS board get graphics more similar to the arcade original. The player starts with three ships and after 10,000 points a bonus ship is given. Asteroids appear in waves. The first one has two large ones and the number increases with each new wave.
