Internal Combustion  (インターナル コンバスション)

難易度の目安:8 (5〜10)

Made from solid brushed aluminum, Internal Combustion is an ingenious design where the object is to free the four interlocked pistons from the chamber. The pistons have notches and look just like ordinary Burr pieces, so you need to learn a correct sequence of movements if you want to put them back in the chamber. Designed by Tado Muroi in the early 1900’s and produced by our PuzzleMaster shop in Canada.
