On the Subject of Y
Y did we have to have two of these?
This module initially is covered by a rectangular panel. When highlighted, this module will show the letter Y. If you see an X, you are looking at a different module.
The alarm clock is linked to this module. Pressing the snooze button then letting the alarm deactivate on its own will open the panel. If at least one X is present, this rule gets swapped with X. The panel always opens from the left.
Once opened, the left square flashes a sequence of black and white, corresponding to a specific column in the image at the bottom of this page, while the right square shows a static coordinate and color.
The left square is white when the seconds remaining on the timer, plus 2 and modulo 30, is white in the same position in the image.
From the left, take the column's position, add 10, and press the snooze button that many times. If it is correct, the module will solve after two seconds.
This module connects with other instances of X and Y. If a given answer is correct on some instances but not on all, the correct modules will solve. However, if no instances can accept your answer, Every single unsolved X and Y will strike simultaneously.
