Luck won’t help you with this puzzle—but you might wish it would! Equal7 is a mathematical masterpiece with two different challenges, each a different level of difficulty. Tilt the cube and slide the dice to and fro, until all the dots on each side equal the same number—10, 11, and 12 are all possible combinations, with more than one way to get there. Once you’ve conquered those combinations, the real test is getting to seven—Equal7! Once you’ve solved it, present your achievement on its own built-in pedestal. Now the puzzle is your trophy!
