Kingdomino

The playing order is determined by the positions of the kings on the dominoes line.

The player, whose king, is placed on the 1st domino of the line (the closest to the box) starts. He must take the following actions:

Add the chosen domino to their territory according the connection rules.
Choose a new domino in the new line by placing their king on it.
Then, it is the turn of the player whose king is on the second domino to take their two actions, and so on, until the last player has taken their two actions.
In a 2-player game, each player will take the D 1 and D 2 actions twice, once for each of their kings.
Then, form a new dominoes line and a new turn can start.
The game is played in 12 turns in 3- or 4-player games, and only 6 turns in 2-player games (as each player plays twice each turn).

Connection Rules

The players must build a kingdom in a 5x5 grid (each domino is composed of two squares). In order to place down their domino, the player must:

Either connect it to their starting tile (the starting domino can be considered as a wild domino, any landscape can be connected to this domino),
Or connect it to another domino matching at least 1 of its landscape (horizontally or vertically only).
If you can't add a domino to your kingdom following these rules, the domino must be discarded and you will not get points for it.
All your dominoes must fit in 5x5 grid. If, due to bad planning, one or more of your dominoes could not fit, they are discarded. You will not get points for them.

End of the Game

When the last dominoes are lined up, the players will take a last turn but they will only take the first action.

Each player should have in front of them a 5x5 grid forming their kingdom. (some kingdoms may not be complete if a player was forced to discard any dominoes - see above). Then, each player will calculate their prestige points for their kingdoms in the following way:

A kingdom is composed of different properties (groups of connected, either horizontally or vertically, squares of the same type of landscape).
Each property will give you as many prestige points as the NUMBER OF SQUARES multiplied by the number OF specific crowns appearing on the property.
You can have multiple properties with the same type of landscape in the same kingdom. ZA property without any specific crowns will give you no points.
Each player will add the points given by all their properties, the result is their final score. The player with the highest score is the winner.

In case of a tie, the player with the most extended property (whether he owns any crowns or not) wins the game.
If it is still a tie, the player who has the most crowns wins the game. If there is still a tie anyway, the players share the victory.
