Friday puzzle -- I can make that
Alex Y
How about a little change of pace and "audience participation" this week, with plans for wooden implementations of classic or "interesting" puzzles.
Here is one that I have played with, but have not made a copy of. The idea is to place different-length pegs in different depth holes, to make the tops of all the pegs equal. I have drawn only seven pegs here, but 8-10 might be better. The pegs are lengths of 1" dowel, cut to lengths that increment by 1/8" to 3/16", and the holes are similarly "spaced" in depth. The base is 8/4 or 10/4, preferably dark wood, so that the depth of the holes cannot be judged easily by eye. (The slanted top already makes for a varied point of reference making the depth hard to judge, but why make it any easier?)
Anybody else have good ones that you, your kids or grandkids have enjoyed working on? Maybe a nice implementation of Towers of Hanoi or of last week's Friday puzzle?
