The Great Minds collection

Great Minds is a Professor Puzzle collection that links each brain teaser to a historical figure; each box includes a short biography of the person and explains how they relate to the puzzle. The display it comes from brings together six models from the collection, three in metal and three in wood, dedicated to Benjamin Franklin, Galileo, William the Conqueror, Leonardo da Vinci, Isaac Newton and William Shakespeare. The pieces have an aged finish that suits the historical theme.

The idea behind the series is that the puzzle also serves as an excuse to get to know the figure a little better: the mechanical challenge comes with a short history lesson.

What level it suits

Professor Puzzle presents the puzzles in this collection as challenging, without giving them a numerical level. The metal models in the series are hands-on brain teasers, in which you need to look carefully at how the pieces relate to each other before moving them; forcing them does not help and can damage the finish. Its small size makes it handy to keep on your desk or to give alongside other models from the collection.
