About SIC-1

SIC-1 - about the game
Programming a Single Instruction Computer challenges you to master subleq, the sole command this processor executes: subtract and branch if less than or equal to zero. Build efficient programs in an esoteric assembly language to secure better job titles at SIC Systems. Refine your code for leaderboard dominance while the company demands your full commitment. This simulation game suits newcomers drawn to its minimal one-instruction design and veterans who relish crafting complex routines from such a restrictive tool. Climb ranks by rethinking conventional programming logic to fit the SIC-1's unique operation. Optimize relentlessly to rise through corporate levels.

SIC-1 is a programming game where the computer only understands a single instruction.

  • Learn an esoteric assembly language.
  • Implement programs to unlock more impressive job titles.
  • Optimize your programs to climb the leaderboards.
  • Sacrifice your personal life for the good of the company!

It's an assembly language zachlike for everyone! New programmers will appreciate how few unique instructions there are to learn (just one!), and experienced programmers will appreciate how poorly suited this one instruction is for writing straight-forward programs.

If you're ready for a challenge, respond to this job posting from SIC Systems:

SIC Systems is hiring engineers to produce highly efficient programs for our flagship product: the Single Instruction Computer Mark 1 (SIC-1).

The SIC-1 represents a transformational change in computing, reducing complexity to the point that the processor only executes a single instruction: subtract and branch if less than or equal to zero ("subleq").

Enter the brave new world of single-instruction computing and invent new ways of implementing programs that would be trivial on a conventional computer. Don't adjust the technology to match how you think, adjust your thinking to match how the SIC-1 operates!
