1. Movement

On your turn, you must move your Scientist between 1 and 3 spaces clockwise around the Main board. You must end your movement on either:

• An inner Action space on the Main board, 
  
• An outer Action space on an Action tile

Inner Circle Actions – to land on an Action space in the inner circle, you must place your matching Creation token.

Passing Creation Tokens – while moving, if your Scientist passes over one or more of your Creation tokens, you must retrieve them.For each token retrieved this way, you may immediately activate one of your Stars, or Gain the Entropy.

Traffic Bonus – traffic Bonuses provide resources or other positive effects, as described in the corresponding action sections.
