Switchtris Lets Commodore 64 Players Explore Six Different Eras of Falling-Block Puzzle Graphics

Emanuele Martorelli releases C64 work-in-progress Switchtris, enabling players to switch dynamically between six historical falling-block visual themes.

A new Commodore 64 puzzle project called Switchtris is exploring how the same familiar falling-block game can appear across several generations of computer and handheld hardware. Developed by Emanuele Martorelli under the smartsoft64 name, Switchtris is currently distributed as a downloadable work-in-progress rather than a completed commercial release. Its central attraction is the ability to switch between different visual themes while playing. Available styles are inspired by arcade machines, the original Game Boy, Commodore 64, VIC-20, Commodore PET and the Soviet Elektronika 60 computer associated with the earliest development of Tetris. Players can change the active presentation by pressing C during gameplay, creating an entertaining comparison of how one basic set of mechanics can appear on radically different systems. The game retains the recognisable objective of arranging falling pieces to complete horizontal lines, while its controls provide joystick-based rotation and a hard-drop option. The developer also mentions an additional slowdown-related mode. Switchtris is available as a PRG download, accompanied by documentation, and the project received an update on October 22. Its current itch.io status remains In Development, so it should not be presented as a finished release with guaranteed compatibility across all configurations. AI assistance has been disclosed for code and graphics. The project is particularly relevant to classic-computing enthusiasts because Tetris itself has an unusually broad hardware history, having appeared on an extraordinary number of incompatible machines. Switchtris treats that history as part of its visual identity. Most games ask players to improve their score. This one also invites them to change the apparent decade while they play.
