This page provides the game and resources needed to play the game Breaking the Silos! We recommend reading the game instructions hand-in-hand with the paper. The paper is freely available at: https://gc.copernicus.org/articles/4/383/2021/gc-4-383-2021.html The game is played using a MIRO board. The link to access it is given in the Game Instructions. The moderator needs to access a Google sheet that will perform the calculations needed to assess the impact of the selected disaster risk reduction measures from the players. We uploaded here the Excel documents but note that some of the formatting may differ. We recommend importing the Excel documents in Google sheets. You can also copy the files directly into your Google Drive from the links given in the Game Instructions. If you would like to cite the game, please use the following reference: de Ruiter, M.
