Mystery Jewels

Mystery Jewels is first introduced in Cookie Run: New World. It can only be obtained from Gold or Special Mystery Boxes. Each Episode has different kind of mystery jewels and requirement to get the reward  is different. Each episode has a special reward. Note that you only can get mystery jewels of that episode by getting mystery boxes from the same episodes.

If players already have all of the rewards for an episode and collect the number of required Jewels again, players will get a reward of up to 16,000 coins.

Trivia

 * It is a good idea to leave the Mystery Jewels unclaimed to increase the odds of getting S/SS rank ingredients and treasure tickets once you've gotten all the prizes.
 * You'll know you've hit the grand prize when the animation for unlocking the prizes becomes a lot more dramatic and flashy.
 * In its early translation, it is planned to be called Artifacts. However, it is scrapped and instead used Mystery Jewels as the name. Players can still see the old translation in the app eyecatch.
