The challenge
Implement a friendly, reliable game loop without high-level data structures, built-in validation, or conventional UI abstractions.
PROJECT 09 / 2026
A classic game rebuilt close to the hardware to explore registers, byte arrays, branching, memory management, and terminal input and output.
CASE STUDY
A quick, clear look at the thinking behind the project.
Implement a friendly, reliable game loop without high-level data structures, built-in validation, or conventional UI abstractions.
A MASM and Irvine32 program with modular procedures for rendering, turn changes, board validation, all eight win patterns, restarts, and exits.
A compact x86 application that handles complete matches, invalid moves, ties, and in-session resets with a minimal memory footprint.
