Sea Island was Bally's second Magic Screen game - they added another section of the screen, and according to Phil's site, bingo.cdyn.com, they made it easier to achieve the feature.
A full extended time tree (after 5th) gives the player the ability to score in each color.
The extra section completely changes the gameplay with the small, difficult blue section.
