Cookie Run: Kingdom allows for the player to add up to 30 other users to their friends list. Being friends with another user allows for the player to interact with them in various ways, such as being able to send messages to them or conduct Friendly Battles with the Kingdom Arena team. The Friends tab sits between the World and Guilds tabs in the social button on the top-right of the player's screen.
Managing Friends[]
Players may add friends by tapping the 'Add' button under the friends list. From there, the player can either search for a specific username or add any of the randomly chosen players under a 'Find New Friends' list. The list consists of 10 other users at a time (showing their username, icon, level, and time of last login) and can be refreshed infinitely with no cooldown.
Next to the 'Add' button is the 'Requests' button. Here, players can view they friend requests they have received and the ones that they have sent. Players can rescind sent requests at any time. For two players to become friends, a request has to be sent and accepted.
To remove a friend, tap the 'Manage' button at the top of the friends list. Here, the player's friends are sorted by their last login, and can be removed by tapping the red minus button.
By default, the friends list is sorted by 'Messages' and shows the most recently messaged user at the top of the list. Messages are automatically sent when sending gifts, either saying "You've received a gift!" or "Gift sent!" along with showing the contents of said gift. Players can also sort the list by Name, Last Login, Kingdom Lv., and Affinity.
Friend Profile[]
From the friends list and add list, players can tap on a user to open a card of the user's overview. The top of the card shows the user's icon, kingdom level, username, arena rank, guild, and total prestige along with 'Likes & Gifts'. The lower half of the card shows Profile, Chat (if added) or Add (if not added), Like, Visit Kingdom, Friendly Battle, and Send Gift options.
Profile[]
Tapping the 'Profile' button brings the player to the other user's Kingdom Info page. It shows the user's icon, username, Arena Tier, Prestige, Decor Points, Kingdom Level, current Kingdom EXP, and EXP needed for the next level. It also shows the Kingdom Life, Adventure, and Active Buffs sections.
The Kingdom Life section shows the user's Cookie Castle level, Wishes Fulfilled from the Tree of Wishes, Trains Sent from the Train Station, Expeditions Sent from the Balloon Dock, Landmarks owned, and Theme Progress as a percentage of all total decorations.
The Adventure section shows the next World Exploration stage that the user needs to clear, as well as the number of Cleared Stages, Completed Bounties, and Arena Battles.
The Active Buffs section shows the number of landmarks currently owned and placed by the user (since landmarks do not provide their buffs when in a player's inventory) as well as the user's Cookie Bonds.
Chat/Add[]
If the user is not in the player's friends list, there will be an Add button. Tapping this will send a friend request to the user that can be either accepted or rejected.
If the user is in the player's friends list, there will be a Chat button. Tapping this will open a private chat box that will show messages and gifts sent by both users. The player's messages will appear on the right while the friend's messages will appear on the left beside their profile icon. All messages are timestamped. If a player tries to send an emoji or other unsupported character, the message bubble will appear blank.
Like[]
Like
Tapping the 'Like' button will send 10 Prestige to the other user. Players can only send one like to each user per day. The number of the friend's total likes (not just ones sent by the player) will be displayed as a number under a thumbs up icon.
Visit Kingdom[]
Tapping the 'Visit Kingdom' icon will bring the player to the chosen user's kingdom. All production buildings will be empty regardless of whether or not they are shown as running or vacant, leaving all of the user's Cookies free to wander. There is no 'Actions' button for the player to easily find specific Cookies, and while the player can still pick up and drag Cookies around, they cannot force them to interact with decors. Players can visit the kingdoms of other users without having to be friends with them.
While at another user's kingdom, their icon, username, Kingdom Level and Kingdom EXP are displayed in the top right (similar to a player's own information when in their own kingdom), though the player cannot tap on this information to open the other user's profile. Beneath this is a number that represents the Affinity score between both players.
Friendly Battle[]
Tapping the 'Friendly Battle' button brings the player to a screen very similar to the Kingdom Arena. It shows the friend's full Arena Defense team without any Cookies hidden as well as their Trophies, Power, and Treasures. Battling the other player's team is free and does not reward either player with anything, but can only be done with either friends or players in your guild.
Send Gift[]
Send Gift
Tapping the 'Send Gift' button will open a menu for the player to send gifts. There are two sections: Random Gifts and Prestige Gifts. Under Random Gifts will be a free Daily Gift (sent once a day per friend) and a Fancy Gift that costs 50 Crystals and can be sent an unlimited number of times. Daily gifts can either be sent individually or through the 'All' button next to 'Requests'. Each day resets at midnight GMT+9, and gifts can be sent even to players that aren't friends.
Prestige Gifts[]
Fancy Gift
During certain events (such as Lucky Holiday Ribbons or Cheers to Our First Year!), an Event Gift will replace the Fancy Gift. Players can send up to 30 Event Gifts a day, though unlike Daily Gifts, these are not restricted to one per user and can all be sent to the same user if the player so chooses. If there is not an event running, players can instead send a Fancy Gift which will contain one of six Prestige Gifts.
Prestige Gifts cost Crystals to send, but will only reward the recipient with Prestige.

Prestige & Affinity[]
Prestige[]
Prestige
Each player has an overall Prestige score tied to their account, earned either from Prestige Gifts or Likes. A player can check their own score in their Kingdom Info and can see other users' scores in their profile. To see a more detailed report, a player can tap 'Details' under their own prestige score or tap the 'Likes and Gifts' button beside the score in another user's profile. Here, one can see a ranking of which users have contributed the most to one user's Prestige. Users' icons and usernames are shown alongside the number of Prestige points they've contributed. In the Details section of a player's own prestige score, they can choose to hide the usernames of certain users in this list.
In the Menu section, there is an option to view Prestige Ranking under Arena Ranking. Tapping this will show a leaderboard of users with the highest Prestige score on the user's current server.
Affinity[]
Beside the username of each user in a player's friends list is a small heart and a number. This is the Affinity score between both players, which can be used to sort a player's friends list by interaction. Sending a daily gift will increase this score by 30 points, an event gift will increase this score by 50 points, and giving any sort of Prestige increases this score by the amount of Prestige given. For example, giving a Like would increase the Affinity score by 10 points.
