In Kingdomino, players are lords seeking new lands to expand their kingdoms. You must explore all the lands, including wheat fields, lakes, and mountains, to spot the best plots, while competing with other lords to gain them first. The game uses tiles with two sections, like Dominoes. Each turn, each player will pick a new domino to connect to their existing kingdom, making sure at least one of its sides connects to a matching terrain type already in play. The order of who picks first is based on which tile was previously chosen, with better tiles forcing players to pick later in the next round. The game finishes when each player has completed a 5x5 grid (or failed to do so), and points are counted based on number of connecting tiles and valuable crown symbols.
