This is Endless Bubble Shooter, this beautiful game has no levels but you continue to play endlessly. A new row comes into play every time the bubbles get too low. This allows you to keep playing. Try to score as many points as possible. The highest score remains noted.
At the bottom of the screen there are 5 buckets, with each bubble you shoot they are filled a little more. Until these buckets are full, when that is the case, the next bubble you shoot is worth double points. These same buckets give you extra points when the bubbles that you shoot loose fall in. The bubbles first bounce against fishes which gives you even more points.
When a bubble falls into a bucket you also receive 1 coin. You can see the total number of coins at the top left of the screen. If you press the plus here you can watch a short video for even more coins (up to 100 pieces!). This ensures that you quickly collect coins. With these coins you can then purchase nice upgrades.
These upgrades are:
