Genuinely a superb maths challenge! There are 12 sections of train tracks. Your task is to construct the railways correctly. However, with each of the 40 graded puzzles youll need to solve maths puzzles and use logical deduction to work out what goes where. The best bit. Once youve completed the puzzle, the wind-up train will go speeding around your solution! Absolutely brilliant!
