The puzzles we present here use the pieces as building blocks only, and present many versatile challenges, from all types of recreational mathematics fields.

There is something magical and enchanting in those seven pieces that enabled us to find many puzzles and challenges! Almost all the puzzles presented are new, unique and original. Some are based on classic puzzles, as well as more modern ones, modified and presented with using the set of Tangram pieces"--
