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 an episode by getting Mystery Boxes from the same episode.

If the player collects all the jewels required, they can draw to get the prize. The reward is being given from the reward list randomly/without order. For example, a player can get the Special Reward in their first draw, obtaining it after a few draws, or (at the least lucky possibility) obtaining it at the 13th draw. If players already have all of the rewards for an episode and collect the number of required Jewels again, the player will get a Coin reward, usually between 10,000~20,000.

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, and takes longer for you to see your prize. Normal rewards would also emit an orange flash during the opening process, while Special Rewards would emit blue flash (pretty much like the difference between opening A-grade Treasure and S-grade Treasure).
 * In its early translation, it was planned to be called Artifacts. However, that was scrapped and instead used Mystery Jewels as the name. Players can still see the old translation in the app eyecatch.
