SLIDER Hanayama puzzle is a new 2020 release. It is a 3 piece take-apart puzzle. The objective is to remove the flat “S” shaped piece inside the two metal channels. Once removed the two panels will also separate. This is a level 3 puzzle on a scale on 1 to 6 where 6 is the most difficult. Most will find the SLIDER Puzzle an excellent challenge. Requires much thinking, planning and many attempts to remove the “S”-shaped piece. Equally challenging is to put the puzzle back together. Occasionally someone will accidentally separate the pieces and think they are a genius !!!! NOT SO ! Mastering the puzzle means you can disassemble and assemble the two pieces easily. Meaning you know exactly which moves to execute to untangle the pieces and then to re-assemble. NO FORCE is ever required to solve the puzzle. Just a series of clever moves. Recommended for ages 13 to 105 years. NO force rule. Forcing pieces may damage the puzzle !! Includes Red Velveteen Drawstring storage pouch. Measures approximately 3 x 4 inches laying flat.
