## On the Subject of Press X

Due to the fact that gamepads and controllers exist, we unfortunately had to settle with "Press 'X'".

• This module consists of four buttons labelled “X”, “Y”, “A” and “B”.
• Determine which button to press, then determine at what time to press it.
• If a time rule states which button to press, it overrules the button rules.

### Which button to press:

Number of solved modules modulo 4↓ If there are more unlit indicators than lit indicators If there are more lit indicators than unlit indicators If there is an equal amount of lit and unlit indicators*
0 A B Y
1 X Y A
2 B A X
3 Y X B

*0 lit indicators and 0 unlit indicators are equal amounts of both.

### Time to press:

• If there is a lit indicator with label “CAR”, the button you need to press is the “X” button, and there are less than 2 batteries, press any button at any point in time.
• Otherwise, if there are 3+ batteries, press the button when the last digit in the countdown timer is equal to the first digit in the serial number.
• Otherwise, if the button you need to press is the “A” button and there is either a 2 or 5 in the serial number, press “A” when the seconds digits in the countdown timer say 05 or 30.
• Otherwise, if the button you need to press is not “Y” and there is a lit indicator with the label “NSA”, press the button when the seconds digits in the countdown timer are equal to each other.
• Otherwise, press the button when the seconds digits in the countdown timer add up to 9.
