The puzzle is to remove the cannonball from this curious brass cannon.

If you look down the barrel of the cannon you can see the cannonball inside but the opening is slightly oval and it stops the ball from falling out.

This is one of a group of Take Apart puzzles that some refer to as Sequential Discovery or sometimes Progressive Move puzzles. There is no simple, single move, straightforward solution.  You need to find the steps, and sometimes the discovery of tools, to enable you to execute them. These tools may not necessarily be obvious and the deduction of what is a tool and what is not is an important part of the puzzle. This is a bit of a challenge for puzzlers who’ve never done this type of puzzle before but makes a great introduction to this very popular genre of mechanical puzzles.

Based on a wooden version called Cannon and Ball puzzle made from wood circa 1881-1884 that was published in Hoffmann’s Puzzles Old and New by Professor Hoffman in 1893.  This puzzle also has the same mechanism as the Bits & Pieces reproduction done in the 1990’s.

We have previously sold a more cheaply made version by of this puzzle made by Enigma but the puzzle proved so popular that we decided to commission this version. The muzzle of the cannon is made from solid turned brass rather than plated cast zinc alloy. The red cannon base is made from a cast alloy metal.  We have opened every one of these puzzles here at Mr Puzzle in Australia to make sure that the puzzling element is set correctly before sending them out.

The solution enclosed is also photographed and worded by us here at Mr Puzzle Australia to ensure the solution is as clear as it can possibly be.

Size: 70mm x 32mm x 30mm
Packaged in a brown kraft card box with a step by step solution worded by us here at Mr Puzzle is enclosed.

    It was a really great puzzle and I felt super satisfied completing it, however, there was one flaw with it, a certain move was really difficult to do as it was tightened too far. But overall, great quality and looks fantastic.

    Fun, be careful, don't use external tools(!)

    Looks snazzy.
    Just get the ball out of the cannon. How hard is that?
    The solution is in obscurity, for those who know brass puzzles.
    Resist the temptation to use any external tools, because brass is a soft metal and scores/deforms easily.
    Using any pliers or tools could actually damage the puzzle if you don’t know what you are doing.
    If you are doing the puzzle correctly, no more than strong finger force is required to solve it!
    There are no magnets, no spinning, not even the force of gravity is required (only to tip the cannon ball out at the end).
    All it requires is at least one functioning eye-ball and a pair of working hands with moderate dexterity, connected to an enquiring mind!
    All of what you need is in the brass cannon, enough said.
    The red base is to display the cannon, nothing more. The wheels and axles have absolutely nothing to do with the solution. The crossbar on the cannon barrel does not come out!
    A cannon by itself would look silly without a stand!
    Have fun!
