ClockWerx is a puzzle game developed by Callisto Corporation for the Mac and PC in 1995. It was picked up and published by Japanese media company Tokuma Shoten for the Super Famicom, Sony PlayStation and Sega Saturn. All three console versions were released exclusively in Japan and were developed by Axes Art Amuse. The PlayStation and Sega Saturn versions include claymation cutscenes.
The goal of the game is to navigate a screen full of nodes to reach a specific point. Along the way are various traps that have a fixed patrol around the screen. The player walks clockwise or anti-clockwise around each node, and can move to another at the moment when their head is touching the node in question. They can also switch direction. By using these two abilities, the player can move across each screen, carefully avoiding obstacles and reach the end.
Tetris creator Alexey Pajitnov is featured prominently on the box art of the PC/Mac version and the title screens of the console versions. However, he had no involvement with the game's development.
