Innovative learning:  Try the CWS Cleanroom Masters challenge for experts and beginners.

Cleanroom Masters is the name of the innovative board game developed by our colleague Britta Heck together with industry colleagues Carsten Moschner (Dastex) and Jürgen Blattner (BSR), which even won 3rd place at the Cleanzone Award 2020. It combines knowledge transfer with the fun of a game, and thus conveys rather dry topics such as standards and regulations with a high fun factor.


  • Cleanroom Masters game board involves a circuit with 24 fields, which schematically represents a cleanroom
  • The starting and end point is the Personnel airlock
  • The aim of the game is to become a Masters Champion by being the first person to get 6 Master Chips back through the airlock by rolling the dice and  answering questions correctly
  • The challenge consists of 600 questions and answers in 6 different categories
  • Action areas provide excitement by drawing attention to mistakes that can be made in the cleanroom

A game that even does good

Cleanroom Masters can be obtained in exchange for a donation. Just donate at least €50 to Kinderhilfe e.v. ( or Primaklima (, mentioning the keyword “Cleanroom Masters”, submit your donation receipt to us and we will send you the game.
