The key to this DUMMY is to recognize that the tabular ordering of successive columns (or files) is in terms of the functional (positional) ordering: the alpha ORDINALS, not the numbers themselves, whether the CARDINAL integers of a MAGIC SQUARE or any other structured array (even a random one!?) or the NOMINAL values in BINGO. (I used average values for ZINGSBOX puzzle). In effect this provides an insight to what was most likely the ‘origin’ of the gaming concept which was adopted to become the conventional ‘roulette on a grid’. The beautiful mathematics was probably not understood by the person or persons who introduced it – or it was ‘lost’ – all that survived was the one to one matching idea along ‘rows’ and diagonals (and other groupings).
