Not Blue Arrows — Keep Talking and Nobody Explodes Module

On the Subject of Not Blue Arrows

I mean, you have a point.

On the module are 4 directional buttons, and a small screen in the middle.

If the buttons are not Blue, or the screen is not initially showing a 3-digit number, you’re looking at a different module.

To disarm the module, use the four buttons to manipulate the number in various ways to get the number to match the Target Number, and then tap the screen to submit. Submitting an incorrect number will generate a new Target Number.

Determining the Target Number

There are two lines on the screen – one at the top, and one at the bottom.

Use the chart below to convert them into a Hexadecimal digit.

The Target Number is equal to the value of the top line multiplied by 0x10*, plus the sum of the bottom line’s value and the product** of both lines.

* 0x10 is the Hexadecimal value 10 (16 in decimal)

**A product of two or more number is the result after they have all been multiplied together
