Description

Description:

Hold TUMBLEBUG between the thumb and second finger at the point marked "A" on Fig 1, with the base resting on a firm, level, flat surface (not too slippery).

Note that point A is not vertical but is slightly overbalanced toward the left. (the illustration assumes that you are right-handed).

Now release TUMBLEBUG (no pushing!).

If you have not solved the puzzle, it will rock down on its convex side and settle in the position shown in Fig 2.

However, if you have correctly solved the puzzle, it will continue on through the position shown in Fig 3. and finally end up with a satisfying thump with its concave side down, in the position shown in Fig 4.

Having solved the puzzle, you will no doubt know how to reset it for the next puzzler.

It must be the most difficult Frank Chambers puzzle and one (if not the) of the most original Chambers. I don't really know on which category this puzzle should be.

It comes with the original solution
