On the Subject of Forgetting Everything

I’m not sure what this is, and at this point I’m too afraid to ask.

• Take the whole dial values for Stage 1. This stage is counted as a valid stage.
• For every other stage:

1. Determine it’s color.

• If 3 unique colors are shown, the stage color is the color that is not shown.
• Otherwise, the stage color is the color that appeared at least 2 times.

2. Determine if the stage is valid.

   • If both numbers in the nixie tubes are on the dials, this stage is valid when presented on the module.
   • Once the module is ready to be solved, sort the stages in ascending order and go through them one by one.
     • If the last two stages are both valid, this stage is invalid.
     • If the last two stages are both invalid, this stage is valid.
     • Otherwise, if the stage is valid when presented on the module, this stage is valid.

3. Take the dial value.

   • Take the dial with position (last digit of the stage number, 0=10)

Solving the module

• For every valid stage, use the table below to determine what operation to use to modify your solution.
• You should only modify the desinated dial position for each valid stage.
• Replace the number at the dial position with your answer.

Colour	Red	Yellow	Green	Blue
Operation	Answer = Previous + Current	Answer = Previous - Current	Answer = Previous + Current + 5	Answer = Current - Previous

• Previous means the current dial solution number. Current means the current stage dial number.
