The object of the game is to create a rectangular shape of six marbles of the same colour whilst trying to prevent the other player from doing so first. Each player starts with one set of 16 marbles of the same colour which are placed in the spaces around the edge of the board. Players take turns to throw the die & then place one of their marbles onto the board on any available space matching the colour thrown on the die. If the player throws a joggle (the side of the die which shows all four colours) then the marble can be placed onto any available space of any colour. Play continues in this manner until a winning position has been created or until all marbles have been played onto the board. Once all marbles are on the board if a winning position has not been created then play continues & on each throw of the die players then choose to move one of their marbles to an available space matching the colour thrown on the die. If a joggle is thrown once all marbles are in play then the player can move a marble to any available space of any colour or alternatively may swap the position of one of their marbles with one of the opponents marbles. However a player may not swap positions with an opponent to complete a set of six marbles. Players can only move & swap their marbles when all marbles have been played on the board.
