For someone like me who loves numbers and loves doing simple math, this game is an awesome way to unwind. Its premise is fantastic - reach 24 using all of these four numbers and basic math operations. 24 is a good choice -- it is low enough so the math rarely gets difficult, and there are indeed many ways to get there. And this game has so many puzzles (sets of four numbers) that I doubt Ill ever run out (because my attention spans a little short, lol).
