In the books, children from all over the world play the game Superhelden.nl. If you finish the game, you’re exceptionally good at something and potentially a superhero. All these kids are kidnapped and brought to the island of Pala to be trained to be real superheroes
In the Netherlands we not only have the books, we also have the game. Readers can play the game, which consists of a series of questions, two mini-games and a Minecraft-like exploration game which takes place underneath the surface of the island of Pala. Click here to play the game (only available in Dutch).
In Germany the books have been published without the game.
