ABOUT THE GAME
Review research and policy decisions every quarter
``Critical Window'' is a strategy game about competition between countries over AI development. We will choose the allocation of research resources and policies, and proceed through the 16 quarters until 2030 while monitoring the state of society and the movements of partner countries.

Allocate research to competency, safety, and dissemination
The research ability for each period will be divided into three categories. At the same time, we are thinking about developing skills, understanding safety, and disseminating it to society.
Select policy and reporting response
Select a policy card every quarter and respond to subsequent reports. Resources, public opinion, and the situation in the partner country play a role in the decision.
Trying again in a world with different uncertainties
