UB Challenge

A UB Challenge (Japanese: ウルトラチャレンジ Ultra Challenge) is a type of special stage in Pokémon Shuffle that features Ultra Beasts. These stages only appear if the player has completed Stage 300. Additionally, the player must pay Coins ×20,000 to unlock the stage for up to 10 plays; each play costs Heart ×1.

A UB Challenge stage for Buzzwole.

No items are allowed in these stages. Exp. Booster L ×5 will be awarded the first time an Ultra Beast is defeated.

For the game's end of service period, UB Challenges began running on a consistent 24-week schedule, with a UB Challenge starting every third week (with the exception of week 24), and lasting for one week. During the game's live service period, there were 6 different UB Challenge events, and the item rewards for clearing them tended to change when a stage was reran. The end-of-service events are nearly identical to the live versions, though the item rewards have been made uniform, and Pheromosa was added to the lineup.

Rotating stages

These stages are available on a rotating basis during the game's end-of-service period, repeating every 24 weeks.

Trivia

• While no UB Challenge runs during week 24, an Ultra Challenge for Necrozma does run during that time. This may be a reference to Necrozma frequently being compared to Ultra Beasts.
