To perform an action, you use 1 of your 4 Action cards (more on the individual actions later). These are located below your Zoo map and each have 1 arrow pointing upward at a numerical value. This numerical value determines the current strength of the action. The further to the right the Action card is, the higher the numerical value to which the arrow points (i. e., the stronger the action).

After you have used an action, you place its card in the leftmost slot under your Zoo map and slide other cards to the right. (This will be explained in detail later.) This way, the card you used becomes weaker and the other cards become stronger. Try to keep that in mind when choosing your action.

During the game, you can upgrade your Action cards if you meet certain conditions (more on this later, see Step 5: Upgrade Action Cards). You upgrade your Action cards by flipping them over to side II. The arrow on that side points at the number on the right. This means that the strength of an upgraded action is always 1 higher than that of a non-upgraded action.

In addition, you can then do more with one action, e. g., play 2 Animals instead of 1.

EXAMPLE: Your Project action currently has a strength of 3.

If you upgrade the Water Animals action (so that it now shows side II), its strength increases from 4 to 5.
