I recently rediscovered this childhood game and remember it giving hours of entertainment (as they say). How it survived intact to this day is a mystery to me.
The game was introduced by Tryne Specialties of Sayville NY in the postwar period with a double version in 1954. This example was licensed to International Games of Canada of New Toronto, whether they imported or manufactured it, I do not know.
The object is to move pieces horizontally or vertically, every move has to be a jump, with the jumped pieces removed, till no more moves are possible.
Seems it could have a future as a phone app!
