The online game "Aqua blocks" invites fans of puzzles in the style of "Lines" and "Tetris" to spend their leisure time with logical tasks. In the game you will go to visit the sea kingdom in the possession of Neptune. The son of the lord of the seas will throw blocks at you, and you need to connect them in a line. For the convenience of the process, the field against the background of the underwater world is lined into cells. Blocks in the form of geometric shapes "Tetris" in three pieces are issued at the bottom. Fold them on the field so that you get solid lines without gaps. Such rows will disappear. The excess will remain hanging, and you will have to fill voids with the help of new figures.
