Clu Clu Land

Clu Clu Land is an original arcade game from Nintendo, released for the Famicom (NES) in 1984, in which the fish Bubbles explores underwater mazes in search of hidden gold bars.

Bubbles cannot simply turn: she grabs the poles in the maze and swings around them. By swimming over hidden gold bars, she reveals them, and when all are found, a picture appears. You have to avoid the sea urchins and the black hole.

It is a simple but addictive arcade game.
