In this game, it’s a play on those “connect the 3 bubble” games. There is a circular like maze that bubbles travel through and your turtle has to try and shoot his colored bubbles to remove the fast moving train of bubbles.
Bonus bubbles are indicated with a “3x” or “7x” or other to indicate how many extra points you score.
There are many levels.
It may not seem obvious but there are obstacles in the aquarium that will block your bubbles (seashells, weeds, etc). It is NOT a bug. So plan your shoots accordingly.
The sound effects and music is very relaxing and not eye-piercing, making it ideal if you need to play something and be discreet (like at work).
