Start playing Digital Invaders today – a classic game available in Casio calculator model MG-880 in the early 80s. This theoretically endless number matching game is addictive, easy to play, and difficult to master! Match numbers and blow them up before they get all the way to the left of the screen! Every 30 seconds the game’s speed increases, but match five of the same number to slow it down and go for the high score. Digital Invaders features: THE GAME THAT KEEPS YOU COMING BACK FOR MORE Numbers are generated randomly but you’ll find yourself strategizing which numbers to take out and which ones to let go until you can destroy 5 for the bonus! Leaderboards will have you wanting to challenge your friends and the community. HOW TO MAXIMIZE YOUR CHANCE AT A HIGH SCORE Every 30 seconds the speed of the game increases. The good news is so do the point values. So the longer you can stay alive the higher the score multiplier will be! Have fun playing Digital Invaders, the best retro Casio watch clone game around!
