KLightsOut is an implementation of Lights Out, a handheld electronic puzzle game. The game consisted of a 5 by 5 grid of buttons containing lights. At the start of a game, a pattern of lights would be switched on. Pressing a light would toggle it and the four adjacent lights on and off. The goal of the game is to switch off all of the lights. KLightsOut expands on the old Lights Out gameplay with larger boards, more states, and holes in the board.
Kinonk is a Pentominoes program written in C++. Pentominoes is a two-player board game where the goal is to be the last player to put a pentomino (a piece composed of five squares) on the board. Kinonk can also play Katamino, a variant of pentominoes. It uses a simple brute force algorithm, and can play any position perfectly if given enough time. You can constrain its time by giving an arbitrary time limit, or simply let it analyze everything. Charts can be generated using a Perl script included in the package.
