The UFO Plate Puzzle is a compact, precision-designed puzzle with a secret storage compartment. It looks simple - sleek duralumin, clean lines, a palm-sized disc - but the mechanism is deliberately deceptive. Traditional clues like sound, touch and visible seams won't help you here. Solving it requires a different way of thinking, making it a special addition for collectors who like puzzles that break the rules.
The difficulty of the puzzle changes depending on whether you use the hidden hint. A sticker on the bottom hides an important clue: if you leave the sticker in place, the difficulty remains 10/10, while removing the sticker and revealing the clue lowers the difficulty to 3/10.
