Monomals is a game about fishing and music. You drop your line into the water, catch a fish and make music along the way. There are different animal DJs to choose from, each with a different sound and 21 different underwater courses to fish in.

Completing these levels grants you access to different sounds instruments, drums and what have you. These are used in the song-created part of the game to craft musical masterpieces with simple tapping and dragging. You can then listen to your songs while you play subsequent levels.

Because the game is online, you can share your creations and rate other people's music to rise or fall through the charts. There are also weekly contests for creating the best of a certain kind of music.
