Do you fancy yourself a mathematician? Are you a visual learner? Perhaps you just enjoy a good challenge? Whatever the case, this mind-bending puzzle is for you. Start by placing all 12 number buttons randomly on the Brainteaser. Now your task is to position the 20 dotted tiles so that all the dots surrounding each number button add up exactly to the number on the button. Victory is yours when all the numbers on the dotted tiles match the surrounding dots, with no dotted tiles left over. Test your skills repeatedly by simply swapping a few number buttons...and voila - you have a new challenge to solve!
