To start, take the first 4 dominoes from the box and line them up numerically, terrain side down. The lowest number should be at the top of the vertical line, and the highest number at the bottom. Then, flip them over so the terrain side is exposed.
To determine the order in which players will select their first domino, one player takes all the king meeples in their hand and pulls them out one at a time. The first king meeple to be pulled indicates which player can select first etc. Players select their first domino in this order, placing their king meeple on a domino to claim it.
When all 4 dominoes are claimed, select 4 new dominoes from the drawing pile. Again, line them up numerically, terrain side down, next to those already selected. Then, flip them over.
In a 3 player game, when 3 dominoes are claimed, select 4 new dominoes from the drawing pile and discard the leftover domino. Line up the new dominoes numerically, terrain side down, next to those already selected. Then, flip them over.
