BonBon

The BonBon Puzzle, designed by Frédéric Boucher, is a masterfully crafted packing challenge that combines elegance with complexity. At first glance, its five tetromino pieces and rectangular box may seem straightforward, but the puzzle demands over a dozen precise moves and rotations to achieve the singular correct solution. (In the solved state, all pieces sit flush within the box with nothing sticking out.) This intricate sequence requires careful analysis and spatial reasoning, making it a rewarding endeavor for puzzle enthusiasts.
