Manufactured in nickel plated wire, the Panic Attack won’t give your heart a rest. The object is to simply free the string from the heart-shaped frame, but that’s only half of the challenge. You will also need to return the string to its original position, so a correct understanding of the solving method is essential. The design is highly original and was actually entered at the 26th IPP by the name of Love Secret. Its designer, the Russian Kirill Grebnev, has a number of other interesting puzzles, among them the beautiful Cast Harmony, winner of two awards at the 30th IPP.
