My first electronic handheld game was most probably the Casio Calculator ‘Space Invader’ game, or more correctly – ‘Number Invader’ game. It was actually modeled after the late 70s popular Space Invader game.
I don’t really remember the model of that Casio calculator, but a Google search shows me the model MG-880. Wonder if it was the same calculator… Anyway it looks alike;

The player have to press the correct number on the extreme left to match any of the number on the right that keeps coming out randomly, so as to kill ‘it’. The 3 horizontal short lines on the right of the extreme left number indicates the number of lives you have remaining. The ‘n’ is what makes me remember the game most!
Here is the closeup of the screen;

So when was this calculator game in fashion? It should be in the early 80s, during my Poly time. Now where have I dumped this calculator???
For those that wish to try out this ‘Number Invader’ game, here it is;
The instructions are here.











My first game was on this Amiga computer in 1979. It was Chomp Chomp. I played during office hours. Got so addicted until can skip lunch.
Another excellent post which stirred up wonderful memories for me as a kid. I used to spend hours on end on this thing! And I must say that I was quite good at it. This was my version of Xbox360 in my day…
Thanks for this wonderful post, Mr Lau!!
Hi Peter, do you mean PacMan? Don’t quite remember Chomp Chomp is the same as PacMan.
Hi Daddyto3, so do you still keep that calculator? I think I lost mine.
yes game = Pacman. The one was = pinball
Hi. I find your blog interesting as I’m able to connect to the articles you have in your blog. I remembered playing the Casio calculator games. It was the craze at that time. Cheerio
Hi Gerard, welcome here. Hope you enjoy the blog here as much as you enjoyed the game.
I actually bought that calculator on ebay a couple of years ago. (just for nostalgic reasons)
All the boys had them at school in 1980…..and us girls used to chat up the boys after school just so they would lend us their calculators for the night….lol
Ahhh, memories……..
