Designed by Finnish puzzle creator Vesa Timonen, the Cast Infinity puzzle was inspired by the mathematical symbol for infinity (∞), which symbolizes endlessness and continuity. Released by Hanayama, the puzzle features two interlocking loops that must be disentangled and then reassembled—a deceptively simple yet tricky task. Cast Infinity is rated as a level 10/10 on the difficulty scale - mind boggling and ranks 6 stars in the Huzzle puzzle series, making it challenging for puzzlers of all levels. Its elegant design and smooth metallic finish add to its appeal among collectors.
