Cast Amour, part of the Hanayama Cast Puzzle series, was designed by the talented Akio Yamamoto. The puzzle's heart shape symbolizes the theme of love and connection, with two interlocking pieces that must be separated. Yamamoto's inspiration came from the concept of a bond, challenging players to "break" and "restore" it through clever manipulation. Despite its delicate appearance, the puzzle presents a moderate challenge, with a difficulty rating of 5 out of 6 stars and 9/10 in terms of overall difficulty. The sleek design and romantic symbolism make it a favorite among collectors and puzzle enthusiasts alike.
