Variant Section 3: Number Chit Placement Restrictions
The restrictions help to avoid unbalance in the potential settlement sites. In discovery scenarios, you should redraw the number chit if the drawn chit violates these rules.
1. Special Rule: No number may be placed in a hex adjacent to a hex with the same number in it.
2. 6's and 8's may only be placed on an empty non-desert land hex that is not adjacent to an already deployed 6 or 8. 6's and 8's should be deployed first.
3. 5's and 9's may only be placed on any empty non-desert land hex that wouldn't create a junction (potential settlement site) with more than 2 of 5, 6, 8, or 9. 5's and 9's should be deployed after 6's and 8's.
