De-ruption is a brass dexterity puzzle designed and produced by Phil Wigfield. It is part of a limited edition series of three separate dexterity puzzles. Only 100 have been produced of each style. Every puzzle is numbered and signed.
Using a bit of imagination, you can see that the inside of the puzzle has the shape of a small volcano. There are 4 rocks (balls) that you need to get back inside the volcano to clean up the mess. There are no cunning tricks; you just need a bit of time, patience and luck.
Each puzzle is handmade using a manual mill and manual lathe, and includes an acrylic top to stop the balls from coming out. There will be small machine marks which can't be polished out.
