My Casio Calculator Invader Game

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.

    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.

    This was my very first “computer” game!!!
    I used to spend hours playing it when I was in JC.
    Once I played for 4 straight hours and busted the highest of high scores – my score filled the screen with 9s…
    memories… thanks for writing this entry.

    method of muscular development for quite some time. They do what works for them, but those

    You really make it appear so easy along with your presentation however I find this topic to be actually something
    which I think I would never understand. It seems too complex and very large for me.

    I’m taking a look forward on your subsequent publish, I will attempt to get the hang of it!

    There’s the oar to the left, which is in the corner.
    You will need to mix a cup of it in a gallon of water and then scrub
    the affected area two or three times until all the traces
    of mold have been removed. Mold can be cleanup up if done properly, but if done improperly you can make the damage worse.
