The Pocket Kit is an all-in-one board game multi-use games system kit. Composed of 3 decks, The Pocket Kit is not a game in itself but a games system which hosts a massive library of already existing games that can be played with it, by utilizing certain parts of a card and focusing your attention on just those parts to play a game of your choosing. The cards within The Pocket Kit are all dry erase for marker use, eliminating game components, although it does work with 8mm colored cubes to help.

Both diamond decks can be played together for certain games, but mainly operate separately, however they both utilize the Side deck which is made up of maps, game boards, guide cards, etc. Some games are played just using the Side deck. Both the White and Black Diamond decks are numbered for easy sorting to play different games.
