Dive into an underwater world and match blue bubbles, pink coral bubbles, yellow starfish bubbles, green seaweed bubbles, and purple seashell bubbles. Each bubble has a translucent look and makes a “pop” sound when cleared. The gameplay introduces a “Tide Line”—a horizontal line across the middle of the board; if a connection path crosses this line, an extra turn is allowed (permitting up to three turns).
You must observe the positions of all bubbles on the board, find matching pairs, and connect them with a path. Paths can consist of a straight line, one corner, or two corners (with three corners allowed when crossing the Tide Line). Each time a pair is cleared, the Tide Line shifts up or down by one row, altering the connection rules.
The 860 levels are divided into eight ocean zones, ranging from shallow waters to the deep sea. Time limits gradually decrease from 110 seconds to 80 seconds. Later levels (beyond level 600) feature “Ocean Current Whirlpools”—specific grid cells that connect to the board’s edges, enabling wrap-around connections. The objective for every level is to clear all the bubbles.
