The Gunmetal V3 is a highly refined addition to the advanced collection, featuring a distinctive “stamatic” labyrinth that offers a deep and absorbing challenge. Solvers are tasked with uncovering its inner enigma through patience, logic, and precise control.
 
With an average solve time of 40 to 60 hours, Gunmetal demands a considered and unconventional approach, pushing even experienced puzzlers to their limits. For the most rewarding experience, it is recommended after completing Indigo or Copper, both of which help prepare you for the techniques and endurance required.
