Revision 3
Welcome to the dangerous and challenging world of bomb defusing.
Study this manual carefully; you are the expert. In these pages you will find
everything you need to know to defuse even the most insidious of bombs.
And remember — One small oversight and it could all be over!

Strike
Indicator
Defusing Bombs
A bomb will explode when its countdown timer reaches 0:00 or when too many
strikes have been recorded. The only way to defuse a bomb is to disarm all of its
modules before its countdown timer expires.
Example Bomb
Front
Side
Modules
Each bomb will include up to 11 modules that must be disarmed. Each module is
discrete and can be disarmed in any order.
Instructions for disarming modules can be found in Section 1. "Needy" modules
present a special case and are described in Section 2.
Strikes
When the Defuser makes a mistake the bomb will record a strike
which will be displayed on the indicator above the countdown
timer. Bombs with a strike indicator will explode upon the third
strike. The timer will begin to count down faster after a strike
has been recorded.
If no strike indicator is present above the countdown timer, the
bomb will explode upon the first strike, leaving no room for error.
Gathering Information
Some disarming instructions will require specific information about the bomb,
such as the serial number. This type of information can typically be found on
the top, bottom, or sides of the bomb casing. See Appendix A, B, and C for
identification instructions that will be useful in disarming certain modules.

Section 1: Modules
Modules can be identified by an LED in the top right corner.
When this LED is lit green the module has been disarmed.
All modules must be disarmed to defuse the bomb.

On the Subject of Wires
Wires are the lifeblood of electronics! Wait, no, electricity is the lifeblood.
Wires are more like the arteries. The veins? No matter…
A wire module can have 3-6 wires on it.
Only the one correct wire needs to be cut to disarm the
module.
Wire ordering begins with the first on the top.
3 wires:
If there are no red wires, cut the second wire.
Otherwise, if the last wire is white, cut the last wire.
Otherwise, if there is more than one blue wire, cut the last blue wire.
Otherwise, cut the last wire.
4 wires:
If there is more than one red wire and the last digit of the serial number is
odd, cut the last red wire.
Otherwise, if the last wire is yellow and there are no red wires, cut the first
wire.
Otherwise, if there is exactly one blue wire, cut the first wire.
Otherwise, if there is more than one yellow wire, cut the last wire.
Otherwise, cut the second wire.
5 wires:
If the last wire is black and the last digit of the serial number is odd, cut the
fourth wire.
Otherwise, if there is exactly one red wire and there is more than one yellow
wire, cut the first wire.
Otherwise, if there are no black wires, cut the second wire.
Otherwise, cut the first wire.
6 wires:
If there are no yellow wires and the last digit of the serial number is odd, cut
the third wire.
Otherwise, if there is exactly one yellow wire and there is more than one
white wire, cut the fourth wire.
Otherwise, if there are no red wires, cut the last wire.
Otherwise, cut the fourth wire.

On the Subject of The Button
You might think that a button telling you to press it is pretty straightforward.
That’s the kind of thinking that gets people exploded.
See Appendix A for indicator identification reference.
See Appendix B for battery identification reference.
Follow these rules in the order they are listed. Perform the
first action that applies:
1. If the button is blue and the button says "Abort", hold the button and refer
to "Releasing a Held Button".
2. If there is more than 1 battery on the bomb and the button says "Detonate",
press and immediately release the button.
3. If the button is white and there is a lit indicator with label CAR, hold the
button and refer to "Releasing a Held Button".
4. If there are more than 2 batteries on the bomb and there is a lit indicator
with label FRK, press and immediately release the button.
5. If the button is yellow, hold the button and refer to "Releasing a Held
Button".
6. If the button is red and the button says "Hold", press and immediately
release the button.
7. If none of the above apply, hold the button and refer to "Releasing a Held
Button".
Releasing a Held Button
If you start holding the button down, a colored strip will light up on the right
side of the module. Based on its color you must release the button at a specific
point in time:
Blue strip: release when the countdown timer has a 4 in any position.
White strip: release when the countdown timer has a 1 in any position.
Yellow strip: release when the countdown timer has a 5 in any position.
Any other color strip: release when the countdown timer has a 1 in any
position.

On the Subject of Keypads
I'm not sure what these symbols are, but I suspect they have something to do with
occult.
Only one column below has all four of the symbols from
the keypad.
Press the four buttons in the order their symbols appear
from top to bottom within that column.

This is like one of those toys you played with as a kid where you have to match the
pattern that appears, except this one is a knockoff that was probably purchased at
a dollar store.
1. One of the four colored buttons will flash.
2. Using the correct table below, press the button with the
corresponding color.
3. The original button will flash, followed by another. Repeat this sequence
in order using the color mapping.

On the Subject of Who’s on First
This contraption is like something out of a sketch comedy routine, which might
be funny if it wasn't connected to a bomb. I’ll keep this brief, as words only
complicate matters.
1. Read the display and use step 1 to determine which
button label to read.
2. Using this button label, use step 2 determine which
button to push.
3. Repeat until the module has been disarmed.
Step 1:
Based on the display, read the label of a particular button and proceed to step 2:

On the Subject of Morse Code
An antiquated form of naval communication? What next? At least it's genuine Morse
Code, so pay attention and you might just learn something.
Interpret the signal from the flashing light using the
Morse Code chart to spell one of the words in the table.
The signal will loop, with a long gap between
repetitions.
Once the word is identified, set the corresponding frequency and press the
transmit (TX) button.

On the Subject of Complicated Wires
These wires aren't like the others. Some have stripes! That makes them completely
different. The good news is that we've found a concise set of instructions on what
to do about it! Maybe too concise...
Look at each wire: there is an LED above the wire and a
space for a "★" symbol below the wire.
For each wire/LED/symbol combination, use the Venn
diagram below to decide whether or not to cut the wire.
Each wire may be striped with multiple colors.

On the Subject of Wire Sequences
It's hard to say how this mechanism works. The engineering is pretty impressive,
but there must have been an easier way to manage nine wires.
Within this module there are several panels with wires
on them, but only one panel is visible at a time. Switch
to the next panel by using the down button and the
previous panel by using the up button.
Do not switch to the next panel until you are sure that you have cut all
necessary wires on the current panel.
Cut the wires as directed by the following table. Wire occurrences are
cumulative over all panels within the module.

On the Subject of Mazes
This seems to be some kind of maze, probably stolen off of a restaurant placemat.
Find the maze with matching circular markings.
The defuser must navigate the white light to the red
triangle using the arrow buttons.
Warning: Do not cross the lines shown in the maze. These
lines are invisible on the bomb.

Fortunately this password doesn't seem to meet standard government security
requirements: 22 characters, mixed case, numbers in random order without any
palindromes above length 3.

Only one combination of the available letters will
match a password below.

Section 2: Needy Modules
Needy modules cannot be disarmed, but pose a recurrent
hazard.
Needy modules can be identified as a module with a small
2‑digit timer in the top center. Interacting with the bomb
may cause them to become activated. Once activated, these
needy modules must be tended to regularly before their timer
expires in order to prevent a strike.
Stay observant: needy modules may reactivate at any time.

On the Subject of Knobs
Needlessly complicated and endlessly needy. Imagine if such expertise were used
to make something other than diabolical puzzles.
The knob can be turned to one of four different
positions.
The knob must be in the correct position when this
module's timer hits zero.
The correct position can be determined by the on/off configuration of the
twelve LEDs.
Knob positions are relative to the "UP" label, which may be rotated.
