Google's search page features a playable Snake game today, the kind we used to play on our antiquated Nokia cellphones. This is of course all in celebration of Chinese New Year 2013.
(It's the year of the Water Snake, by the way. Lucky colors are blue, green, teal, aqua, black--all the colors of water. That much I remember from all those Chinese horoscopes I've been skimming.)
Anyway, for purely nostalgic fun on your smartphone, get the Snake '97 app from Google Play. As the name implies, it's a homage to the classic snake game, done verbatim--from the dot-matrix display to the lime-green glow of the screen, to the beeping sounds--just as good as if you were back to using your old Nokia (dumb)phone. It's clunky too, just like the original.
