Gobliiins is a puzzle game with adventure elements. The player controls three goblins - Oups, Ignatius and Asgard (Hooter, Dwayne and BoBo in the US release) - as they search for four magic components to calm down their king Angoulafre. A voodoo doll has gone mad and turned the king into a rager, and the only one who can restore order is Niak the Wizard.
The game requires solving puzzles by combining the different skills of each goblin. The player can switch between them and control them separately, using action icons at the bottom of the screen to activate their abilities. Most of the puzzles involve coordinated actions - one goblin can cast powerful but unpredictable spells, another can collect and use objects, while the last can hit things.
The game is divided into 22 stages, each with its own set of puzzles that must be solved to progress. The characters have limited energy, which can be depleted by traps, making strategy and planning crucial to success.
