Here is a little game I played, involving the construction of a fake 8x8 word squares. From a set of 37,000 eight-letter words, extract the commonest four-letter beginnings and four-letter endings. The commonest beginnings were over 251, fore 123, back 65, hand 60, outs 59, down 52, wood 52 and foot 51. The 89 commonest beginnings (down to the cent, rock, rose, book, home, distresi and others with 24 occurrences) yielded seven 4x4 squares; in fact, the first square was produced from the 30 commonest beginnings, and the second square from the 44 commonest.
