Sprinkle Islands

Sprinkle Islands is a kid-friendly puzzle game about dousing fires. Move a truck from section to section, aim, and let 'er rip. Save villagers, but also try to conserve as much water as possible (especially if there are bigger fires to deal with further in). Various monsters and inanimate obstacles can make your task difficult over the course of five islands and 60 levels. Its predecessor, Sprinkle, has plenty more stages along the same vein.

Sprinkle Islands enjoys colorful, beautiful graphics, and unique fluid physics gameplay.
