Popular games for platform Sinclair ZX81

It's the year 2081 and servant robots have become commonplace, though too expensive for most people. In that same year, a large abandoned Sinclair warehouse is discovered with thousands of mint, working ZX81s and some genius decides to build a line of cheap and affordable robots using them: The Zeddytrons. Based on ZX81s and huge rampacks (by 2081, rampack science has advanced significantly) the Zeddytrons become massively popular and the world fills with them ... until the unexpected happens! Wobblying rampacks cause the Zeddytrons to malfunction and declare mankind an obsolete species! Your mission is to move through 50 waves, blasting Zeddytrons, avoiding undestructible Zeddyhulks and rescuing human survivors! You can control your player using AWSD to move and JIKL to shoot simultaneously in 8 directions. Otherwise, you can use OPQAM / Cursor / ZXPand+ Joystick to move and shoot by pressing fire and the direction in which you want to shoot. Good Luck!

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 idea is to build up lines of 3 matching symbols horizontally or diagonally to score points and gain a little time. 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.

3D Monster Maze is a computer game developed from an idea by J.K.Greye and programmed by Malcolm Evans in 1981 for the Sinclair ZX81 platform with the 16 KB memory expansion. The game was initially released by J. K. Greye Software in early 1982 and re-released later the same year by Evans' own startup, New Generation Software. Rendered using low-resolution character block "graphics", it was one of the first 3D games for a home computer, and the first game incorporating typical elements of the genre that would later be termed survival horror. 3D Monster Maze puts the player in a maze with one exit and a hostile monster, the Tyrannosaurus rex. There, the player must traverse the maze, from the first-person perspective, and escape through the exit without being eaten.
