Worms: The Board Game Advent Calendar lets you build your game one day at a time over 24 days. Each day reveals a new component, including Worm miniatures, terrain pieces, dice, and tokens. By the end of the calendar, you'll have a complete game ready for 2-4 players. The set includes a fold-out play mat, modular terrain, dice, tokens, and a rules booklet. Miniatures are supplied unpainted and may require assembly; washing models in warm soapy water before gluing is recommended. Players can set up the terrain in different ways to create new challenges and play styles. The advent calendar format offers a step-by-step way to build the game and introduces each component gradually, providing a structured and interactive setup experience.
