Many such resources include upgrades that can be purchased with coins. For example, once the player has a citizen of the kingdom with a tool, they can build defensive walls. As the player gathers more resources, new options to spend coins will open up. Initially, such resources will include hiring wandering travelers (vagrants) to become part of the kingdom and creating smiths to craft weapons and tools. As the character passes landmarks, these will produce a few coins, from which the player can pick up by riding over them, and spend on various resources, which will be marked with open coin slots when the character passes near them to purchase an upgrade, the player must be able to provide all the required coins at that time. The player can move the character on horse to the left or right, including at a gallop, but has no other direct action. The player starts the game with a randomly generated king or queen on horseback.

Kingdom is presented to the player in a pixel art, two-dimensional screen, with the goal to build up and create a kingdom while surviving various foes that will attempt to capture the player-character's crown, effectively ending their rule. Kingdom received generally positive reviews appreciating the game's art and music, and its approach that required the players to figure out what to do based on these elements, but felt that the tedious nature of some tasks in the game affected its end-game and replayability. The player has otherwise little direct control of the game, and thus must use the coins they collect in judicious ways. The game is played out on a pixel art-based two-dimensional landscape the player controls a king or queen that rides back and forth, collecting coins and using those coins to spend on various resources, such as hiring soldiers and weaponsmiths, building defenses against creatures that can attack and steal the monarch's crown which will end the game, and otherwise expanding their kingdom.
