I’m sorry about your confusion! Which values were not clear enough? Do you mean special placeholders?
Uh, the balance bars! You have to mantain them in the “grey zone” (green and red recall the color of the cards that push in that direction).
There are 4 bars (one for each zone: north, south, east, west) and you have to keep them “balanced”: the value -indicated in the box next to it- must remain between “-20” and “20”. With -21 (due to the green cards) or 21 (due to the red cards), you lose.
And… under “Settings”, you can re-open the tutorial at any time :)
