Android Rundown: It pleases me that logic games are popular. There is nothing wrong with a game’s sole purpose being for you to run as fast as you can while shooting things, but I do appreciate the elegance of some mental concentration leading to a solution. It takes time, and the ah-hah moment, to me, is worth a thousand combo-kill point bonuses. Naturally, when Sudoku exploded I was instantly hooked. I began carrying the puzzles around with me everywhere, because they are the perfect moment-filler. But eventually they became too easy, and I suppose I was waiting for something to take their place.
