Lot 6291 - Winston Freer Tile Puzzle Trick

Designer: Winston Freer
Maker: Tom Lensch

Size: 28x23x2cm

Notes: The Winston Freer Tile Puzzle Trick is a modern classic of puzzling mathematical magic. The trick is performed by successively removing three one-unit blocks, yet each time maintaining the overall dimensions of a 9x7 rectangle. However, unlike the Curry Paradox, on which the trick is based, the pieces fit perfectly (no hidden gaps) in the 9x7 tray both before and after the trick is completed. Included 4-page instructions for presenting the trick (see video).
