Love numbers? Then this one’s for you. It offers wildly challenging, brain-busting math puzzles that really test your arithmetic logic. Like a regular crossword, it features a grid that you have to fill in by solving clues. But here, one clue may refer you to another one, which you’ll then have to figure out first to go further. For example, the solution for 21 Down might be: 34 Down Septupled. You’ll then have to go to 34 Down to see what it says. Nothing’s obvious, so you’ll have to think hard and do some smart calculations. In case you need a little help, there are "starting hints” that give you a few answers to get you going.
