27// MagicJam
28//
29// Jam is a multi player game. It is controlled by its context menu (click
30// with the right mouse button on one of the pixels in the game pad).
31//
32// Start the game with:
33// MagicJam jam;
34//
35// Rules:
36// MagicJam is a multiplayer game. The aim is to own the full game pad.
37// Ech pixel in the pad can contain as many entries as it has neighbors.
38// If it has more entries than neighbors it overflows into its neighbors.
39// All pixels into which such an overflow occures will be captured by
40// the current player. Player by player will be able to increase the
41// entry in one pixel by one. Increase the contents of an empty pixel to
42// one or by one in an owned pixel. The player who once will own the
43// all pixels will win.
44//
45// Editor:
46// To edit or create a new game start the editor from the context menu
47// of MagicJam. The editor is also controlled from its context menu.
48// Use the curso keys to shift your game.
49// Warning: You MUST create a single-island game. Games which have two
50// islands might result in edless loops. (Currently there is no check!)
