I wrote the following in a 1979 magazine that I sent out to interested customers. It featured new games in stock. (BRW, it cost nearly 3 pounds back then).
CABAL Rimberry Ltd.,
A two-player game of bluff and counter-bluff, Cabal is simple to learn and great fun to play. Much of the time is spent carefully studying the board and then your opponent's face, and then the board......and so on.
Neatly packaged, the equipment consists of a plastic playing board, coloured pigs and two plotting boards. The rules are concise and easily understood - all rules for the three variations of the game fit nicely on the bottom of the box.
Players decide who's going to be the Escaper and who the Trapper. The Escaper starts at the centre of the board and to him the edge of the board spells freedom, and therefore victory. Meanwhile the Trapper's aim is to halt the Escaper's movements.
A blue peg (the Escaper's) is placed in the centre hole on the board and he then has a choice of eight possible directions in which to move (imagine he's in the middle of a noughts and crosses grid) - he plots his first move to freedom on his plotting board, concealing it from his adversary, of course.
The Trapper, meanwhile, plots his course of action using three different coloured pegs - red, yellow and green. Both parties' plotting boards are the displayed simultaneously.
If the Escaper has managed to avoid all the Trapper's three pegs the game continues as before.
But, if the Trapper has blocked the freedom route, then the colour of the 'blocking' peg determines the next course of action. If it's yellow the Escaper stays where he is and a yellow peg is placed on the main board; if red the same thing happens but a yellow and a red peg go on the main board; if it's green the Escaper is allowed to move but a green peg is placed on the main board - though not immediately adjacent to the Escaper. Gradually the barriers build up and the paths to liberty become fewer and fewer.
The game ends when the Escaper has left the board or when he's unable to move without being caught.
Cabal's a great little game for all ages and its compact presentation makes it ideal for travelling.
