The 6-digit computer is a programming game in an alternate past. You, Deam Mead, just got hired at Farworks as a programmer for their new operating system, HTaeD / O6. However, it's not as simple as you might think! The computer operates on bijective senary, which means that it only has the digits 1-6. So 7 becomes 11, 24 becomes 36 and so on. (Please make sure that all of the numbers displayed in the Features below are in bijective senary).


-56 increasingly challenging tasks!

-User-friendly programming system!

-16 devilish (literally) Elite Tasks for those who want a real programming challenge!

-3 different endings!

-Unique artstyle!

-A soundtrack with both the classic tracks and new remixes by misotanni!

-And a dark secret...


Drag and drop commands with your mouse, or hover over command places and press the respective hotkeys. Overall, you mainly need to use your mouse.

I'm having trouble optimizing puzzle ID_312564 (Double the digit of the number) in the limit of 5 commands. Would you be able to give me a hint, please?

You've probably realized that adding 6 [SAVE] times adds too much. Try adding [SAVE] instead.

If you're completely stuck, check out this handy tutorial by misotanni:

FYI This is a rather old and discontinued game, so I'm happy to hear there are still people interested in it!

Will this game be available on Steam in the near future?

No, I don't think we will be releasing games on Steam yet. I will think about this though and perhaps our next game will be on Steam.

Update: We will be now making Mordent, which wil be only on itch.io, but our next-er game, CYBERDRIVE, will be on itch.io and on Steam.
