There are two regular unit ares (cell) arrays: (1) "square" and (2) "hexagonal". The first includes a chess or checkers board. These have no central cell. The other array has symmetrical cells which include the centre cell. Both the other arrays are asymmetrical. The first array needs to be the most distinctive and both the asymmetrical arrays need to complement it by being th same colour/tone. see roseboardgames.org for details. mjj
