Comment Too bad it doesn't come with digital invaders (Score 4, Informative) 78
Some of the Casio watches back then had a game on it called digital invaders where numbers would "invade" from the right, and you had to match the numbers streaming in to destroy them. There is a standalone version on Google Play: https://play.google.com/store/...
I've also seen other versions on the web... There may be an iOS version as well.
Anyways, those watches were highly prized as they could provide much needed always available boredom relief back before cell phone games. I'm surprised that casino's current models (or this one) do not host the game. It would be a trivial cost and effort to add it on with today's technology.
