Slayaway Camp Bruteforce Solver

This is a bruteforce solver (and, completely incidentally, commandline version of) the excellent puzzle game "Slayaway Camp", by Blue Wizard Digital:

I believe I started on this when I got stuck on one of the "NC-17" levels and figured I'd try my hand at writing a bruteforce solver for the game. Along the way I had so much fun putting it together that it became a fully-fledged console version of the game, in addition to having level definitions for basically the entire base game.

The console version certainly leaves quite a lot to be desired from a UI perspective, since it's really only in there because I wanted a way to easily test out functionality. It'll look like this:

Interactive Mode

When run in non-interactive mode, you'll get output like this:

$ ./ -l s2_s04
Winning moves (11) for Slayaway Camp 2, Scene 4 - Triple Truncheon:
        1. South
        2. East
        3. North
        4. West
        5. South
        6. South
        7. East
        8. North
        9. West
        10. South
        11. North

The game has levels defined for all of the "main" Slayaway Camp levels (ie: Slayaway Camp 1 through Slayaway Camp X), plus the NC-17 levels for Slayaway Camp 1.


Slayaway Solver was written in Python. It should work in Python 2.7 or Python 3.x without problems, though it's mostly just been run in 3. I recommend using PyPy/PyPy3, though performance is generally fine using plain ol' CPython.

Slayaway Solver requires the colorama Python module, to make the interactive output a little more palatable. If you want to use PyPy3, an easy way to get this installed appropriately is using virtualenvs:

$ pypy3 -m venv_slayaway
$ . venv_slayaway/bin/activate
(venv_slayaway) $ pip install colorama
(venv_slayaway) $ ./

Commandline usage is pretty simple:

usage: [-h] [-i | -t] [-l LEVELNAME]

Play or solve Slayaway Camp levels

optional arguments:
  -h, --help            show this help message and exit
  -i, --interactive     Run interactively rather than in solver mode (default:
  -t, --test            Generate python code suitable for a unit test
						(default: False)
						Level name to run (use "list" to get a list) (default:

As mentioned, to get a list of all levels that it knows about, specify --level list or -l list as an argument.

The -t/--test argument is mostly just for my own purposes to add it into our unit test area. They aren't actually real unit tests; rather it just checks each level against previously-found solutions.


Performance is actually quite good when using PyPy3 instead of CPython. (And in general it's not bad even when using CPython). Our test suite, which tests all levels except s10_d4 versus known solutions, completes in just under fifteen seconds on my system. They complete in 52 seconds using CPython.

"Slayaway Camp X, Deleted Scene 4" (s10_d4) is currently the longest to solve, clocking in at at a little over 1 minute, on my CPU (using PyPy3). Its solve time goes up to 4:20 or so when using CPython.

Interactive Use

The interactive UI for this definitely takes a bit of getting used to. Your available commands are just w, a, s, and d (for north, west, south, and east). You can also undo moves with u, reset to the initial state with r, and quit with q.

The symbols used in the UI to indicate the map:

  • P - Player
  • V - Victim
  • E - Exit
  • C - Cat
  • L - Police (will use ←↑→↓ to show which way they're facing)
  • S - SWAT Cop (will use ←↑→↓ to show which way they're facing)
  • O - Police targeting reticle
  • H - Hazard (pit, fire, etc)
  • M - Mine
  • 1/2/3 - Phones
  • | - Bookcase/Cabinet which can be knocked over west or east
  • = - Bookcase/Cabinet which can be knocked over north or south
  • X - Bookcase/Cabinet which has been knocked over
  • ^ > V < - Escapes (only along map edges)
  • ~~~ - Light switches
  • - Gum (sticky patch)
  • - Teleporters (matched by symbol)

A bit of coloration is used to help distinguish things as well. The game map will use a yellow checkerboard pattern to distinguish cells. The exit will be magenta until all victims have been killed, and blue/green afterwards. Half-height walls are in red. Police/SWAT targeting reticles are in red. Electric walls will be bright cyan if active, or blue otherwise. Sticky Goo will be magenta.
