On the Subject of Memory

Memory is a fragile thing... I’m not forgetting something right?

• A Memory/Anti-Memory module will be identified by a question mark in the bottom right corner of the display. If it isn't there, you are looking at a different module.
• Press the correct button to progress the module to the next stage. Complete all stages to disarm the module.
• After completing a stage on Memory, occasionally Anti-Memory will appear. Refer to the following pages if this happens.
• Pressing an incorrect button will reset the module back to stage 1.
• For Memory, button positions are ordered from left to right.

On the Subject of Anti-Memory

Oh right, I knew I was forgetting something!

• Stage numbers here refer to which stage was most recently completed on Memory.
• Press the correct button within 25 seconds to return to Memory.
• Pressing an incorrect button or running out of time will reset the module back to stage 1 of Memory.
• For Anti-Memory, button positions are ordered from right to left.

• Stage 1:
• Take the display from the first stage of Memory and find the button with the same label on the first Memory stage. Take that buttons position.
• Add to that the position of the button on Anti-Memory that has the same label as the current display.
• If the sum is divisible by 4, press the button in the first position.
• Otherwise, if the sum is divisible by 3, press the button in the second position.
• Otherwise, if the sum is divisible by 2, press the button labeled "3".
• Otherwise, press the button labeled "1".

• Stage 2:
• Count how many buttons had their label match their position on all stages of Memory. (e.g label 2 in second position)
• Do the same for all stages of Anti-Memory.
• Take the difference of these two numbers and modulo 4. Press the button in that position, or position 4 if the result is 0.

• Stage 3:
• Count how many times in all stages of both Memory and Anti-Memory the button in the position of the display, has the same label as the displayed number. (e.g display 3, position 3, label 3)
• Modulo the result by 4 and press the corresponding label. If the result is 0, press the button labeled "4".

• Stage 4: (2 Methods will be presented, both lead to the same result)
• Stack each set of button labels from each stage of Memory and Anti-Memory on top of each other in the order they appeared, with positions in ascending order.
• • Original Method
  • Draw four lines between each pair of consecutive stages, where each line connects buttons with same labels.
  • Count the amount of intersections between all those lines.
  • If more than two lines intersect in the same point still count it as only one intersection. (e.g 1234 followed by 4321 has 1 intersection, not 6)

• • Alternate Method
  • For each pair of consecutive stages, consider the amount of swaps needed to get from one to the other. Take note of these numbers.
  • EXCEPTION: If one stage is the reverse of the other, count it as 1 instead of 2. (e.g 3214 followed by 4123)
  • Add up all these numbers.
• If the result is even, press the button labeled "2".
• If the result is odd, press the button in the third position.
