Aquia known as Aquite in Europe and Aquario in Japan is a puzzle video game developed by Skip Ltd. and published by Nintendo for the Nintendo DSi's DSiWare digital distribution service. It was released at the launch of the Nintendo DSi and DSiWare service on April 5 2009 in North America. The game requires players to line up blocks in rows of three or more in order to allow their diver to delve deeper into the ocean. This occurs as they move blocks of various sizes (1 x 2 2 x 1 or 2 x 2) horizontally into a column of coloured blocks. As players move blocks in from one side they push blocks out of the other side. They can move these blocks up and down the column as well as rotating their colours configuration in order to create matches of coloured blocks within the column.
