The source code of all apps is included in the JDroidLib distribution.

LightsOut

The game consists of a 5 by 5 grid of lights; when the game starts, a set of these lights (random, or one of a set of stored puzzle patterns) are switched on. Pressing one of the lights will toggle it and the four lights adjacent to it on and off. (Diagonal neighbours are not affected.) The game provides a puzzle: to switch all the lights off, preferably in as few button presses as possible.

The application is ported from JGameGrid. See here for further information.

Pacman

This is a basic implementation ported from JGameGrid (see here for further information) to keep the code simple for the purpose of demonstration. There are only two ghosts with a simple strategy: One ghost moves arbitrarily through the maze but may block the Pac-Man to move. The other ghost knows the position of the Pac-Man and moves toward him.
