It's a simple but very addictive game, in Ultra Jump the aim is to guide a character called the UltraBoy up an unending series of platforms without falling.
The objective is get as high as you can. Players can get a short boost from various objects, such as rockets or Energy diamonds.

There is no definitive end to the game, but the end for each gameplay happens when you fall or lost all your lives ( 3 lives that can be re added taking the hearts when it appear on your screen)
