Let’s Begin…
They call you the human cannonball. Your act involves flying through rings of fire, bouncing through a trampoline course, and catching the trapezist in the grand finale. Today’s pre-flight test fails dramatically, and upon inspection, your cannon has clearly been sabotaged. Unfortunately, it’s too late to abort the launch. Can you fix it in time to catch the trapezist? Alex Rosenthal shows how.

Does this puzzle remind you of a certain beloved pastime? You might have noticed some similarities to Sudoku, which also requires solvers to apply logic to a combinatorial number-placement puzzle. These types of recreational mathematic games have a long history in popular entertainment, with early “magic square” examples appearing in 19th century French newspapers—for example, this puzzle featured in Le Siècle in 1892. Kordemsky essentially created a stacked version of this type of problem (think 3D chess from Star Trek), using a visual aid (rabbits) as a stand-in for numerical values. Its complexity belies its true simplicity, which characterizes much of The Moscow Puzzles and, we hope, our Human Cannonball riddle.
