"The Game" is a project designed to simplify the process of producing any high-quality cross-platform 2D or 3D graphical computer game. The hope is that any game can be produced simply by changing a few settings and pressing a "compile" button. The project has three "deliverables": a game engine library to abstract across the set of all possible computer games (applying object-oriented design methods to the general problem in such a way as to be usable in specific instances); a graphical interface for easy game design (an exercise in human interface design); and a gaming package with a lot of shiny games to play.
Sudoku.php is a Web-based program that tries to implement the same rules a human would use to solve a Sudoku puzzle. It can solve many Sudoku puzzles, but not all because it only uses logic and refrains from brute-force solving. You can interactively influence the solution process to try out rules of your own. You can easily enter a Sudoku puzzle and save it for repeated use.
