This game is a legit way to potentially win money, but it's best if you enjoy shooter games, and that's the primary reason you play. Then any winnings are a fun bonus. Keep in mind that while the app is legit, you might lose money if you don't win the cash games you participate in.

Bubbles is a 2D action game developed by Williams Electronics and released arcades in 1982. The player uses a joystick to control a bubble in a kitchen sink. The object is to progress through levels by cleaning the sink while avoiding enemies.

Try to get every fruit within reach, but don't make foolish moves that fill up your board. Fruit will quickly help fill the Zuma-meter to finish a level. Chain bonusses (every consecutive shot makes a set of 3 or more balls; hitting fruit will not break the chain) can be quite a bit more helpful than you'd think.
