Version for Atari 8bit:

This computer game is based on BrainTeaser by Wim Nijland.
Choose digits from 1 to 9, split by reaction method into three groups: 1-3-7-9, 2-4-6-8, and 5.
The goal is to display all digits except 5, avoiding the field clearing.

@yevrowl what 16bit machines is it supposed to run on? And what's the exe for?

Runs on 8-bit Atari PCs — 400/800/XL/XE. The executable file requires Atari DOS.

Maybe you could use an AI to convert it to other platforms?

Have repeatedly tried to use AI chats, but they are clearly not suited to retro programming. Have to rely mainly on my own skills and good advice.

There is a plan to develop a version for the Atari ST. :mrgreen:

The logic game was developed and tested on Amiga 1200 (UAE emulator). Did not notice any problems with functionality...
