The objective of the game is to blast through bubbles and reach the bottom of the ocean to rescue mermaids.

You can blast two or more bubbles of the same color or with the power-up.

You can also use the power-ups to blast through obstacles and reach the bottom of the ocean.

Once you reach the bottom of the ocean, you can find mermaids that need to be rescued.

You can blast through the ocean and reach the mermaids by matching your fish's color with two or more bubbles of the same color.
