If you want to turn up the intensity, hit pause (or press ESC or P) and change the game speed setting.

If you want to beat all 50 levels of this classic game, you'll need enormous concentration and memorization! The levels only get harder as you progress, so focus becomes a more and more important attribute. 

Run 1 is one of the oldest popular titles here at Coolmath Games. While the game came out in 2008, it wasn’t uploaded to our site until 2012. It was an immediate hit due to the engaging gameplay and interesting premise. Since then, it has remained popular for over a decade.
