Trap Castle Guide: How to Read a Room Before It Kills You

Trap Castle has 32 trap rooms, eight in each of its four wings, and a boss waiting behind every wing. Each of those rooms carries a written hint. The knight shows it in a speech bubble after the third death in a room, and again after the sixth and the ninth. Collected together, the hints read like a field guide to the castle, because nothing in it is random: every trap has a tell that shows before it fires.

32trap rooms in four wings
4bosses, one per wing
3deaths before the knight gives a hint
14knight corpses a room remembers

The corpses matter more than they look. Each death leaves the knight's body where it happened, and a room keeps up to 14 of them for as long as the player stays in it. A pile of armour on one tile is the castle admitting where its trap is.

The tells

Tell What it means First seen
Crack in a floor tile Fake floor, it drops 1-1
Tiny holes in a block Hidden spikes 1-2
Shiny gold keyhole The real door 1-4
Dull grey keyhole A painted door 1-4
Door that drools A mimic 1-7
Red eyes in armour It swings when close 2-3
Wall that shimmers Not really there 3-1
Red book on a wall A switch 3-2
Gargoyle smoke Fire is next 4-1
Chest that breathes A mimic 4-2

Spikes also push up whatever sits on them, crates included. In 1-3, Box Office, the wall is too high to jump, and the way over is to shove a crate onto the spike blocks and let the spikes lift it into a step.

The signs lie, and they are signed

Many notices in the Dungeon and the Throne Tower are signed by the Architect, the castle's builder. In the Library, the signed ones come from the Librarian. Both are worth reading for the joke and then ignoring for the facts.

  • 1-1, Welcome, Brave Knight: "The exit is right there. Totally safe. Promise!" A cracked tile sits right in front of the door.
  • 1-2, Mind the Holes: "Those tiny holes in the floor? Purely decorative." They hide spikes.
  • 3-5, Liar's Library: "Solid floor all the way to the exit!" Floors in that room shimmer too.
  • 4-4, Do Not Press: one sign says to step on the plate, another says never to press the big red button. The plate drops a crusher. The button opens the door.

The Armory is the exception. Its signs are numbered house rules, closer to warnings than lies. Rule 2 is "cannonballs have right of way." Rule 7 says that nobody has ever completed the Gauntlet.

Wing by wing

The Dungeon teaches the vocabulary. Pressure plates only hold a gate open while something heavy stays on them, and the knight does not count: in 1-5 it takes a crate. Crushers fall a moment after the knight passes underneath, so the only safe speed below one is full speed. In 1-8, Arrow Hall, the stone face fires at anything at its height, and the answer is to drop down behind the crate and push it all the way to the door.

The Armory is about timing rather than tricks. An axe only reaches the floor in the middle of its swing, so the moment to run is right after one passes. Awake armour can be baited: step in, step back, and run past while it recovers from the swing. In 2-4 the lever that opens the far gate also drops something on whoever stands under it, so the knight keeps running after pulling it. In 2-5 the exit door runs away and has to be chased into a corner, over the cracked tile and the holes it crosses on the way.

The Library of Illusions bends what counts as solid. Mirrors are doors to other mirrors. Flying books in 3-4, Bookworms, follow fixed paths, so the safe place is right behind one that has just turned. In 3-6, Reading Room, a crate cannot go through a mirror, but a crate left on the plate downstairs still opens the gate upstairs. In 3-7 the shimmering wall is to the left of the start, with something red hidden behind it.

The Throne Tower mixes everything. Real treasure sits still. In 4-3, Crown Jewels, touching the crown drops every crusher in the room at once, so the jump goes over the pillow instead. In 4-6, Throne of Lies, every door upstairs claims to be the exit, and only one keyhole shines gold: teeth mean mimic, a dull keyhole means paint.

Room 4-2, Treasure Trove, just after a real coin. The two chests further along still need a look before anyone jumps near them.

The four bosses

Boss The opening
The Jailer, Keeper of Keys, Hater of Knights Too heavy for cracked floors. Stand past the cracks and let him charge across, three times.
The Iron Golem, Nobody Home, Everybody Hurt Jump the rocket fist. When the chest glows, step on the plate and the arrow hits the cog.
The Grand Mimic, The Door That Eats Doors Only one door has a gold keyhole. It leads up to a lever, pulled while the Mimic stands under the chandelier.
The Architect, Designer of Doom, Drafter of Disaster Grab the glowing blueprint, dodge sideways from the red aim line, and treat white sketches as falling blocks.

The Jailer fight has a test of its own. An early version let him walk onto the cracked floor by himself and lose without the knight doing anything. He now stops at the edge when walking, and only a charge takes him across. A test file in the game's code, boss1idle, still runs the fight with a knight standing idle at the entrance, to make sure that bug can't come back. The 32 trap rooms have scripted playthroughs too, one per room, which prove every room can be beaten.

Crowns and the results screen

A room cleared without a single death awards its crown. The results screen grades everything else, and its four lines are worth knowing: no deaths gets "Flawless!", one or two get "Not bad, tin can.", three to nine get "The traps send their regards.", and ten or more get "The skeletons are forming a union."

The usual route to a full set of crowns is two passes: clear each room once any way possible, then return knowing where every trap sits.

The knight moves with the arrow keys or A and D, and jumps with Space, the up arrow, W, Z or K. R restarts a room, and gamepads work as well.
