With almost 240 million possible combinations you'd be forgiven to think that the Meffert's New Generation Puzzle (NGP) is unsolvable, but you'd be wrong. With four difficulty levels from which to choose from, anyone from a boisterous five-year-old to Grandma and Grandpa can enjoy its challenging play and have the ability to solve the first level. This will then gently exercise and train the mind to progress to the next level until the puzzle is eventually solved. The NGP is exiting to play, and can be addictive too. The Meffert NGP is also the world's first mechanical puzzle, featuring a unique Twin Axis ball-bearing mechanism, making it easy and effortless to turn and twist. Stimulates the mind, hand and eye co-ordination.
