Cookie Run: Kingdom – Instructions to unlock Rainbow Shell Gallery

The store selects a random cookie each refresh and up to 5 Soulstones of this cookie can be purchased here. There are also EXP Star Jelly, Topping, Magic Cookie Cutter, most especially Guild Relic and Soulstone of Legendary level cookies. This shop is the only place in the game for gamers to purchase rare Soulstones and Guild Relics.

Unlike the other shops in the game, the player cannot unlock the Rainbow Shell Gallery immediately, but needs to do some love to be able to access it. The following guide will help players unlock Rainbow Shell Gallery in Cookie Run: Kingdom to collect valuable items.

How to unlock Rainbow Shell Gallery

Upgrade the castle to level 8

This is the first step that players need to do to meet the requirements to unlock Rainbow Shell Gallery. Upgrading castles helps gamers unlock more advanced production buildings. It also allows building more cookie houses, helping the kingdom thrive.

Each time they level up a castle, everyone will have to follow a list of requirements, listed when touching the castle. The castle upgrade will take some time to complete. Lower level castles will take hours or days, but higher level castles can take weeks or even months to complete.

Fortunately, upgrading from a level 7 castle to a level 8 castle will only take two days. Here are the requirements for level 8 castles:

1. 6 Aurora Pillar, 6 Aurora Brick and 6 Aurora Compass.
2. There are 700,000 coins.
3. Compete 20 times in the arena.
4. Bought and booked the Latte Cafe building.
5. Own 10 cookies with a minimum of level 24.
6. There are 2200 decorative points in the kingdom.
7. Completed stage 5-28.
8. Received rewards from Bear Jelly Train 10 times.

Remove 2 boxes next to the tent

After upgrading the castle, the next step is to clear the space so the player can build the Rainbow Shell Gallery. In the lower part of the island, the player can see a tent. Click on it, it will display the message Expand surrounding territory first.

This is the part of the island that gamers will have to clear in order to build Rainbow Shell Gallery.

Touc's mission

After the player completes the steps above, they will be greeted by Touc in a side quest. These missions will reward gamers with coins and EXP Kingdom. It should be noted that the kingdom level is different from the castle level. After completing all missions, the player will unlock Trade Harbor and Rainbow Shell Gallery simultaneously.

How to collect Rainbow Pearl

Rainbow Pearl is the currency that players use to purchase items from the Rainbow Shell Gallery. They are given as rewards from Trade Harbor. Refer to the Cookie Run: Kingdom Item Trading Guide for how Trade Harbor works.

Hard-to-produce goods will give players more trading points. Players should save at least 3600 Rainbow Pearls every 3 days, to be able to buy a Legendary level Soulstone, worth 2000 Rainbow Pearl, and 2 Guild Relics costing 800 Rainbow Pearl each.

Buying Soulstone Legendarts every 3 days is important as gamers rarely get them from gacha and can't buy them anywhere other than Rainbow Shell Gallery.

Buying 2 Guild Relics is also important because the drop rate of Legendary relics is similar to getting past level 40 in Alliance mode, which is extremely challenging that even experienced gamers can't beat.
