What it is
TIS-100 is an open-ended programming puzzle game by Zachtronics. Players rewrite corrupted code segments to repair a fictional computer, using an assembly-language programming system built around interconnected nodes. The game presents a reference manual for exploring how the machine works, then sets more than 45 puzzles where solutions can be measured by cycle, instruction and node counts. It also includes three sandboxes for designing challenges, one of which is a visual console for making games within the game. A broader mystery asks players to uncover who created the TIS-100 and why. Steam features include single-player, achievements, Steam Cloud and leaderboards, as well as a level editor. The listed platforms are Windows, macOS and Linux. This is a puzzle game framed around programming, with its challenges centered on building and refining code rather than conventional action.
