Hello there! We are conducting a survey to better understand the user experience in making a first edit. If you have ever made an edit on Gamepedia, please fill out the survey. Thank you!
Commit Gate[edit | edit source]
A Commit Gate is simple to build: using a single power source, sticky pressure switch, and electric floor (or powered door) that activates the electric floor once the robber moves across. This effectively commits the robber to that path once crossed.
Ways out of it are:
- Water - poured on the floor or power source. Cost: 100
- Saw/Wire cutters - cut through the unpowered floor or wall to bypass the trap entirely. Cost: 400
Invisible Changes[edit | edit source]
Since animals only move once they see the robber, creative use of windows, cats, and dogs can result in seemingly impossible activation (or deactivation) of traps as the animals move behind walls and step on switches.
Ways out of it are:
- Remember the owner must test the design without tools. Stay alert and proceed carefully.
- Bricks & other means to eliminate the threat. Cost: 150+
The Double-Sided Trap Door[edit | edit source]
The idea is, you don't know what's beyond the door until you open it. When you do, if you are unprepared, you are screwed. Best placement for these types of traps is so that your screen doesn't scroll until you enter the door.
Ways out of it are:
- Brick the cat/chihuahua. In some situations chihuahuas are used in a reverse fashion where they walk towards you rather than away from you to hit the switch. If in range, brick the Chihuahua. Cost: 150
- If you can move at all without setting off the traps, do so, then pour water on the trap to walk back. Cost: 100
- Saw the wired wall connecting to the electric floor. Some constructions wire the walls on both sides - in this case, use your judgment. If it's easier to saw one and then walk through to a different hall, or saw both and walk out from whence you came. Cost: 400 or 800
- Use a wire cutter on the electric floor. Cost: 400
The Pit Bull Window Trap[edit | edit source]
A pit bull trap where a pit bull gains line of sight on you through a window, then follows you to a door where the moment you open the door, you die:
The idea behind this one is that, a pit bull cannot pursue you the same move where it makes line of sight with you. So putting the pit-bull directly behind the door deters you, but does not kill you since you are able to walk away. Using this construction, the pit bull makes line of sight first and thus can attack you the moment you open the door.
Ways out of it are:
- Be alert on whether you've seen any windows with a pit bull behind them. If you have, any doors you open are potentially unsafe until that pit bull is taken care of.
- Bricks can be used to open doors from a safe distance. If you are going to go this route, I HIGHLY suggest you leave one tile between you and the door (don't brick a door standing directly next to it) so that if the dog is on the other side, you have an even number of spaces between you. This way you can club it if absolutely necessary. Cost: 150+
- If you can reach the window, breaking it can lead the dog out of its hallway where it might be less of a threat. Cost: 150+
Abusing the View[edit | edit source]
Since the view is only drawn once the player is within 3 squares of the edge, you can force traps and behavior to trigger:
Leap of Faith[edit | edit source]
The other classic is the leap-of-faith. Read up on precedence on the wiki if you want to understand this one.
- The player moves.
- Pet movement occurs.
- House objects and electronics update.
Meaning you can step on to an electric grid which is powered on, then the pet moves onto a button, then the state of the electric floor (and your Schrödinger charred corpse) is determined.
I especially like the variant on this below, which has been ripped straight from my current vault:
This works on three levels. At the newbie level, opening the door at the top and seeing the scary pit incites them to turn around and go back the other way, where a cunningly inviting corridor filled with doggy death doors awaits them.
On the intermediate level, the fellow comes along and sees an unpowered trap door. But then he spies the dog, who will move down a tile when he does, hitting the button. So he bravely steps out into empty space, only to land heavily, crushing his legs and dying a lingering death.
Why did he die? Because there isn't actually any power coming into the pit from the dogs side. Instead the power to the trap door is turned on by doing a little magic dance somewhere far, far away in the maze. Oh, and incidentally this trap door works as a double bluff when it has been powered on. Because the even more eagle eyed expert viewers will notice that's a toggle pressure switch (starts on) which the dog is about to step on, which if they're wrong could switch off the power after all...
Fire Floor[edit | edit source]
Player walks into the house from the right. Up the top, there's open ground (with scary family protections and lots of dogs, maybe an electric door in plain view). Through the door could be anything, maybe even an angry pitbull!
So, because of his initially limited visibility, he takes a step down onto the first grid which doesn't seem to have any power. He sees the third grid around the corner, but figures he's still safe. However when he moves on to the second grid, suddenly the little doggie sees him and gets agitated. If he moves backwards, he gets fried. If he moves right, he gets fried. The only ways out are:
- Neutralize the dog (meat, brick, gun).
- Take a saw to the wall ... at which point, obviously, wall dog.
- Use some wire cutters
So, for $250 you have a basic trap which potentially costs $400 to circumvent. Upgrade the dog to a pitbull, you then have the choice of either drugging him and leaving a landmine in the passage, or spending $1,200 to shoot him.
I'd say this one basic trap accounts for maybe 15% of the deaths in my house. Most of them in 4 moves.
Combination Lock[edit | edit source]
Combination locks are easy to build and difficult to guess without tools. They take up far less room than a multi-path maze and can be easily modified to change the "success" combination to thwart scouting.
Here is a very basic example (credit: [Synthesis]):
The pin here is 1, 3, 5. If they are pressed and 2, 4, 6 are not pressed, there is a signal sent that cuts power to the door. 1, 3, 5 can be entered in any order, as long as they are pressed before 2, 4, 6. To brute force this type of lock it will take at most (2^n)-1 attempts. So this example will be solved in 63 attempts or less. You will want to have traps to prevent people from viewing the door more than once after entering the code or else up to 6 attempts can be made in one house visit (1 | 1,2 | 1,2,3| 1,2,3,4| 1,2,3,4,5| 1,2,3,4,5,6).
You can make locks that need buttons pressed in order, or have the same button pressed multiple times as well. These become much more difficult to brute force, but also require more difficult electronics that take up valuable space.
(credit: [okami316]) Just as a variant that prevents brute force, here's a compact version of what I've used before.
The lock is the same, but they can't simply cut the power for the electric floors or doors due to the powered trap doors also losing power. electric floors and powered doors are interchangeable, just changes the necessary tools to brute force. Also, having it against the wall would prevent breaking the wall from the other side for the code.
