Rainbow Fish: The Most Beautiful Fish in the Ocean is an educational title for three to seven year old children. The aim is to teach math, logic, problem solving, shapes, colours and creativity. It is a single-player game that has two levels of difficulty and which is entirely controlled with the mouse. The story is that Rainbow Fish is the world's most beautiful fish, not just because he has such wonderful colours but because he also has eight very shiny scales. One night, during a big storm, three crabs Bumble, Rumble and Tumble, steal these shiny scales. This story revolves around the adventures of Rainbow Fish and his friends to recover them which they do through a series of mini-games.
