Popular games for platform Sinclair ZX81

20 Years on from the Spectrum game Amusement Park 4000, the Zeddy gets a conversion of the 16K Spectrum follow-up Fun Park for Chroma-enabled ZX81s. So much has been crammed into this game; amazing colour and graphics courtesy of Jarrod Bentley, more visitors and options. 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.

An obscure compilation consisiting of six games for the ZX81.

Endurance is a motorcycle racing simulation game released in 1985 for the Amstrad CPC and Sinclair ZX Spectrum. Up to five players compete in turn-based races across various tracks, managing speed, endurance, and strategy. The game features alternating turns and was praised for its realism and challenge.

Galaxians & Gloops is a double game pack that contains: Galaxians: Based on the arcade game, you control a craft at the bottom of the screen, moving left or right, blasting alien ships in formation above firing missiles at you. As you blast the aliens, some aliens will swoop down firing missiles as well. If you are hit by an alien or its missiles then you lose one of three lives. Before the game you have a number of options that can be selected and they are speed (0-9), firing rate (0-9) and how many swoop at one time (0-9). Gloops: A Pac-Man clone that has you moving about a maze eating all the dots to clear the maze. As you eat the dots, Gloops move around the maze as well and if you touch one then you lose one of three lives. There are power-pills and if you eat one then you can eat the Gloops for a short time. Before the game you have two options that can be selected and they are speed (0-9) and a choice of ten mazes.

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.

Pac Rabbit is a Pac-Man clone where you take the role of a rabbit and you move about a maze eating all the dots to clear the maze. As you eat the dots you must avoid the hounds that are hunting you but you can eat magic carrots which enable you to eat the hounds for a short time. If you touch a hound then you lose one of ten lives. There are six mazes split into two parts, Rabbits Revenge and Run Rabbit Run and you can choose the speed of the game (0-9) with zero being the fastest.

ZX Asteroids is based on the arcade game where you are a craft sitting in the middle of the screen surrounded by large asteroids moving about the screen. You have to blast all the asteroids, and when one is shot then it splits into smaller asteroids and keeps repeating the process until the asteroid has gone. You can turn your craft left or right 360 degrees but you can also move forwards. Occasionally an alien craft will appear and when shot gives you bonus points. If you are hit by an asteroid or the alien craft then you lose one of three lives. Two players can play and each player takes it in turns when the other player loses a life and there are five levels of play (1-5) with one being the easiest.

Raider is a Scramble clone that has you flying over the surface of a planet before flying through a cavern bombing the installations and missile dumps. As you fly, missiles and aliens will fly towards you and you can either bomb them or use your laser. You are able to move your craft up or down, and left or right to avoid the missiles and aliens as well. If you hit a missile, alien or the planet's surface then you lose one of three lives. A fuel gauge decreases as you fly but you can increase it by bombing fuel dumps.

Aventuras na Selva is a text-based adventure developed by Renato Degiovani and published by the magazine Micro Sistemas.

Centopeia is a shooter game where you are the operator of the earth's defense bases, with the mission of frustrating the attack of the terrible fleet of space centipedes that want to conquer our planet.

Stinger is a tank-shooter with several enemies, levels, power-ups and items to pick.

Shuriken is somehow inspired by Pac-man and Pengo.

Galaxians is a clone of Galaxian. The player's goal is to destroy a matrix of enemy spaceships which is gradually descending on the screen. Single ships will sometimes leave the formation and bombard the player with multiple shots. There's only a single scenario with a single type of spaceship. The process repeats itself when a squadron is completely eliminated, but the difficulty increases.

Mazogs is a maze video game developed by Don Priestley and published for the ZX81 by Bug-Byte in 1982. It was subsequently licensed by Softsync and published in the US for the Timex Sinclair 1000.

Games 1 is a collection of six games and programs which contains: Orbit: You control a ship orbiting a star and the further you are the slower you circle it. Also on screen is a piece of cargo orbiting the same star and you must adjust the speed of your craft by moving inwards and outwards to catch it. Sniper: A man appears on the screen in one of ten positions and you must press one of the number keys 1 to 0 where you think he is on screen. Meteors: You control a craft on the top of the screen and you must move left or right through a meteor storm that moves up the screen. Life: A program that was devised by J. H. Conway in 1970 and allows you to see a pattern come to life and hopefully grow. You place cells on a 16 x 16 grid and when you are happy with your placements you can let it come to life. Three cells adjacent to each other produces a cell, two or three neighbours, the cells survive and one or more than three cells, the cells die. Wolfpack: You control a ship on the top of the screen left or right, and you must drop a depth charge to hit a submarine below moving across the screen right to left. You only have one depth charge per sub and when the sub reaches the edge of the screen it has escaped. Golf: You must hit a ball into a hole at a random distance by selecting the range from 35 to 75.

Em Busca dos Tesouros is a platformer developed by then 15-year-old Tadeu Curinga and published by the computer magazine Micro Sistemas.
