cell phone games are great to kill some time. try playing this one at eamobile.com/tiger . it has pretty sweet graphics for a phone game too. any other recommendations?
There's a whack-a-mole style game that uses the number pad that's kind of cool (don't remember the name). Outside of that you can't go wrong with 'Space Invaders' or 'Tetris'.
I'm still searching for some mobile games in the net but sometimes searching something you really want is not appearing...
I'm not much for cell phone games. I had Might and Magic on my phone once, however. I found it utterly fascinating that they put that kinda game on a phone...
