Puzzleball can be an enjoyable, fun challenge for those who enjoy jigsaw puzzles, but it can lead to more frustration than traditional jigsaw puzzles. This spherical puzzle comes with 540 slightly rounded, plastic jigsaw pieces that snap together to effectively hold the 3D globe shape. Unlike traditional jigsaw puzzles where users can start anywhere they choose, this puzzle requires that puzzlers start from the first piece and build out to make the structure hold. As a result, it requires more cooperation than traditional puzzles which allow multiple people to work on different parts simultaneously. Another unique feature is that each piece is stamped with a number on back, so players can be certain they found the correct piece before they snap it in. This feature can be particularly helpful when assembling the blue ocean pieces which all look the same. While this can lessen the potential frustration of trying the incorrect piece, some may find that it detracts from the overall challenge. As students assemble the pieces they can improve their knowledge and retention of world geography, particularly if they work with someone and discuss the countries and oceans as they assemble them. Overall, Puzzleball offers a unique spin on traditional puzzles and can improve world geography knowledge while also developing the traditional jigsaw puzzle skills of spatial perception, attention to detail, and visual scanning.
