Bubble Up Endless is a bubble-shooting game that offers infinite play. The player's goal is to earn as many points as they can by shooting standard and multiplier bubbles hanging in front of a nighttime grass-covered field below mountains. The player uses a ring shooter to knock the ball-like bubbles from the field into point cups. Some bubbles also contain coins that they can use to buy boosters. If the player allows the hanging bubbles to slide below a red dashed line or uses the pause option, they must restart without any points or coins.
