A threat has appeared in our virtual sea, the fish are terrified, and the crabs turned red with indignation, but they can not do anything. Colored blocks rise right from the bottom of the sea and they can fill the entire bottom, and then displace all the water and the sea will dry up. We can't hesitate, start destroying blocks right now. To do this, click on groups of three or more identical square objects. Look for large clusters to quickly destroy them. Don't let the playing field fill up, act faster than blocks. Free the fish that have already been captured by the blocks. Use bonus items: rainbow blocks, bombs and other boosters that simultaneously remove large groups of objects in The Sea Rush.
