Open Source Puzzle Games

A webapp hacking game, where players must locate and exploit vulnerabilities to progress through the story. Think WebGoat but with a plot and a focus on realism&difficulty. Contains XSS, CSRF, SQLi, ReDoS, DOR, command injection, etc

This is a minimalist version of the Sokoban puzzle game that runs on Windows, OSX, and Linux. The best thing about this game that is different: you can use the built-in solvers a little bit.. Sometimes I want to know the best next move or two, but no more. Other times I want to solve part way and watch the solver step thru the remainder of the solution at whatever speed I choose.

TextCodec can encode texts using simple algorithm and then decode them by using statistical language data.

Cryptomak contains cipher and tools for encryption utility written in php such as substitution, vigenere, affine, transposition and index of coincidence. It is powered by Phrame platform which implements MVC design and Smarty template engine.

HumanSudokuSolver is intended to solve Sudoku puzzles in a way human beings would do (non brute force). It currently solves most of the puzzles I tried and can output a step-by-step solution. Developers who want to contribute are welcome!

A java application for creating, playing and solving SuDoku puzzles of various types. Features both a Swing GUI and command-line operation. The automatic solving of puzzles uses "smart" techniques rather than a brute force search of every possibility.

RufaSlider is a collection of 16 different block slider puzzles for kids and casual puzzlers that works on laptops and PCs running Windows, OSX or GNU/Linux. It includes a Klotski-style family, a DirtyDozen family, and a Traffic-Rush family. And now these puzzle families come with AutoSolvers to help you. The Klotski family uses rectangles of 4 sizes: 1x1, 2x2, 1x2, 2x1. The objective in each game is stated near the window top, but usually involves moving a large block to a specified location within the window. The DirtyDozen family is similar except there are L-shaped puzzle pieces. The Traffic-Rush family uses data, with 2x1, 1x2, 3x1, 1x3 rectangles. Here, the long rectangles represent cars or trucks that can only move [roll] lengthwise...the goal being to move the red car toward the shaded "exit door". The proper command to extract the archive and maintain the directory structure is "7z x filename".

This is a simple app, created around an original sudoku solver based only on heuristics, not brute force. It's coded in Java/SWT(GUI toolkit). It's an example of MVC and of Visitor, Observer, Strategy, Abstract Factory, Singleton Design Patterns.

This program solves sudoku grids, using human techniques and brute force. It is written in c++ using Qt.

A set of tools for manipulating and solving pencil-and-paper style ciphers, cryptograms, and related puzzles.

Confiture is the new generation of the cryptographic software, Confiture use the all new innovation cryptographic.

cryptshell is a shell used for analysable code (eg anything before wwII). It automates letter substitution, transposition, and has modules useful for breaking various weak ciphers (enigma, substitution, vinigre). It has no real practical value.

A non-brute-force sudoku solver. Ukodos is sodoku backwards; According to wikipedia, Sodoku is a bacterial zoonotic disease.
