I am addicted to this wonderful little number puzzles. I get on a train, settle myself ( bag in lap, etc, and no sooner do I settle than I whip out the little bound puzzle book and a pen and I disappear inside the number grids.
I look up and it is time to alight. Egad. What must one say!! This is a joy. I am certaint the way I approach them is not the same as anyone else. In fact I would go so far as to say I hav no system, but the number have patterns and it is the patterns I see. That’s how I know which number goes where.
