FREE RETRO 80S CALCULATOR GAME
Calculators really took off in the early eighties and became as popular as mobile phones are today. They started to become more and more sophisticated, and manufacturer's were trying to add as many features as possible, including the game "Digi Invaders" which I remember playing on my Casio calculator.
The game is, of course, based loosely on the classic arcade game Space Invaders. Thankfully, you can now relive a small part of your childhood and play the game for free below!
Instructions: Press the blue base key to start the game. Use the left arrow key on your keyboard to change your number to match the number of the invader coming towards you. Then press the right arrow to destroy it.
