Eric Rodenbeck just pointed me to this gorgeous little game for the iPhone: Drop7. It combines the best elements of Tetris and Sudoku, but somehow transcends them both. While most games start out interesting and then plateau, this one actually gets better with time. It tempts you to come up with ever-more-creative ways to set up the domino-like chain reactions that yield the highest scores. The design is also solidly appealing (hey, with two nice weights of Helvetica, how can you go wrong!) And is it addictive? Ohhhh man, is it ever. The first time I played it, I was on a hard-seated chair. I don’t know how long I was sitting there, but when I tried to stand up, I couldn’t feel my toes. Both of my legs had gone to sleep. It’s that addictive.
My only critique is that every single number is the wrong color. Consult a synesthete next time, ok guys? :-)
