Wegs, not all of Martin Gardner's Puuzzles/Brain Teasers were Mathematical...take for instance this one from : https://www.theguardian.com/science.../martin-gardner-mathematical-puzzles-birthday " 1.

...for some, for others, maybe not so easy. At any rate, for the better part of thirty years I looked forward to Martin Gardners writings/games/puzzles in Scientific American every month. Like I told Wegs, DaveC426913, if you have not already done so : Simply type " Martin Gardner's Mathematical Games " into your favorite 'Search Engine'...then...diversion...fun...brain sweat...are all sure to ensue...!!!
