House Of Mirrors (HoM) is a logic game inspired by Chromatron (from Silver SpaceShip Software). The game consists of a 2D grid in which several types of objects are found, including detectors and mirrors. The goal is simple: light up all the detectors using emitted or reflected rays of light. Usually, you can move and rotate the mirrors but not the detectors. In each level, the choice of available objects is limited. There can be more than one solution for each level. Levels can be created by users in hand-editable XML format and shared with others.
MUSoSu is a free software project for playing, solving, and generating Sudoku games. It is written in Java and emphasizes both solving Sudokus simulating methods used by hyman solvers and generating Sudoku problems that don't require trial and error methods to be solved. MUSoSu is partly themeable and platform independent.
