Professor Puzzle presents The Einstein Collection - a suite of complex 3D Puzzle / Brain Games. In 1905 Einstein’s extraordinary thinking and unique perspective changed the way we viewed space, time, and energy. He also opened the world’s eyes to the power of his phenomenal brain. Few people on this planet wouldn’t know that name, recognize his image, or associate him with superior intelligence. So, what better muse to inspire a collection of puzzles... and what better way to test our own brainpower than to try to solve them?
