We are looking into  ways of introducing a KS3 Magic Square which is more focused on KS3 curriculum goals introducing science concepts, working with  more student input into the design and build  and concentrating on more complicated board games and their mathematical applications  .

The dice workshops  http://inventagame.co.uk/workshops/dice/   and

the board game workshops  http://inventagame.co.uk/workshops/games/   

are particularly relevant for KS3 and can be implemented within the framework of the design and technology ,art , humanities and math curriculums.
