Guild

"Play with your Guildmates and expand your Guild with a variety of activites!" Guilds are a major feature in Cookie Run: OvenBreak, introduced in the Guild Adventures update. Joining a Guild allows players to socialize and cooperate with other players in the Guild, compete with other Guilds in Guild Runs, and earn unique rewards from Exploration Quests and the Guild Shop.

Guilds can be created by players above Escape Level 20 and require a payment of 2,000 Crystals to create. The creator of a guild is the Guild Leader and can choose a name and icon for the Guild and write a short description. Guilds can have a Trophy limit, so that only players with enough trophies may join, or they can be closed and only allow players verified by the Guild Leader to join. The Guild Leader can promote members to Guild Officers, who can kick members, start Guild Runs, and change settings of the Guild's icon, description and trophy requirements. If a Guild Leader is inactive for over 14 days, an Officer will become the Leader. If there aren't any Officers, or the Officer is inactive for more than three days, the member that has participated in the most Guild Runs becomes the Leader.

If the guild is disbanded by the Guild Leader, or if the player is kicked or leaves, a new Guild cannot be created or joined for 24 hours.

Guild Level
A newly created level 1 Guild can go on Guild Runs and play in the Check-in Board. Guilds level up with Guild EXP earned from any Guild member using the Check-in Bingo, Guild Cookie or playing Guild Runs. Higher EXP will grant higher chance of a Special Check-in Board appearing, upgrade to the Guild Shop, and will give Titles.

Guild Hall
The main Guild menu is the Guild Hall. It is a campsite area where players can place their Cookie and, add a message, access Guild information and other Guild features.

The Guild hall lets the player choose any Cookie they own in any Costume they own and place them in one of the different spots in the campsite, and have them say a message up to 60 characters long. The message said can be changed after 30 seconds.

Check-In Bingo!
Every day, you can check in the Check-In Bingo for rewards, such as Sugar Crystals and Guild Cooking Ingredients, and will guarantee 200 Guild Coins and 600 EXP. There are 36 tiles in the Bingo, 6 of which are "Go Again!" tiles, which gives another attempt. You can sometimes get a Special Reward, which has 500 Crystals, 200  Rainbow Cubes, and either a Supreme Cookie Chest, Supreme Pet Egg, or a 10+1 Treasure Incantation. Sometimes, the Bingo Board will be a Special Bingo Board (Higher chance with bigger Guild Levels), that will give better rewards. The Special Bingo Boards can be Crystal Boards, Rainbow Cube Boards, Cookie Chest Boards, or Double Rewards Boards. You can check once a day, but you can pay Crystals 3 times for extra Check-ins at the last hour of the Bingo Board reset. It will cost 100,  200, and than  400 for extra Check-ins on the Bingo.

Guild Chat
The Guild Chat can be accessed from the Guild Hall or Guild Run menus. Chat messages can be up to 280 characters long. A notification is posted in the Guild Chat when a new member joins and when the Guild's Rank increases. The Guild Chat will notify if your Guild is in 1st place in Guild Runs, and you can post Costumes and Jelly Shapes that you got from the Gacha.

Guild Runs
Guilds of at least level 4 can participate in Guild Runs. Guild Runs are competitions between four Guilds of similar Ranks. Guild Runs use multiple different Arenas, specific maps with special rules and a limited selection of Cookies, Pets and Treasures, similar to the Champions League. Guilds are given stars proportionally based on their scores in an Arena, and at the end of a Guild Run the number of stars collected determines the winner.

Each Guild Run Season lasts for two months. The current Season determines the Season Items in the Guild Shop and the available Arenas, as well as any additional Season Rules.

The Guild gains or loses Guild Trophies after a Guild Run based on the total stars collected, and these Trophies determine the Guild Rank. After the current Season is over, players who participated in at least three Guild Runs will receive a Season Reward based on their Guild's Rank.

Guild Kitchen
The Guild Kitchen can be used to cook a Guild Meal that provides a buff to all Guild members during a single Guild Run. Ingredients for the Meal can be collected in Exploration Quests, and added to the pot by all members. The Guild Leader and Officers can decide when to cook, and the ingredients currently in the pot will determine the meal cooked. If the ingredients in the pot don't correspond to any recipe, a Mistake will be cooked. Newly cooked meals are added to the Recipe Book, where players can see the effect and ingredients of every meal they've cooked. A meal cannot be replaced during a Guild Run, but if a Guild Run is started with no meal, one can be cooked.

Guild Shop
Guild Coins can be spent at the Guild Shop. Season Items are limited-time Jelly Shapes available during a single season, and all other items are General Items. More items are available as the Guild levels up.

Exploration Quests
Guild Exploration Quests let teams of cookies be sent out to Exploration areas to receive rewards. The five Exploration areas are Gloomy Woods, Riddleshore, Frostbite Lodge, Black Skull Wasteland, and Dragon's Valley Gates. The number of cookies required, exploration time and potential rewards vary depending on the areas chosen, though all areas will give Guild EXP and Guild Coins. Each area also gives two different Ingredients for the Guild Kitchen. The first area, Gloomy Woods, requires four Cookies and takes three hours, while Dragon's Valley Gates will take ten Cookies a full 24 hours to explore.

A player can explore a maximum of three areas at once, and each Cookie can only be in one of the three Exploration Teams, but the Cookie can still be used in all other gamemodes and suffers no other penalty. Each area has some special Cookies which increase the chance for a Super Reward when selected. This is visible from a glowing aura and a message from the cookie when selected while forming a team. In addition to the Super Reward, there is a small chance for a decreased "disappointing" reward.
