April 2020 Pokémon Spotlight Hours

Trainers, Thank you for all your feedback on Pokémon Spotlight Hour and Mystery Bonus Hour. We’re continuing to test these minievents, and we’re happy to report that we’ll be combining them into one weekly event for the month of April. We wanted to provide some information on this combined event in advance so you can prepare.

For the month of April, Pokémon Spotlight Hour will take place every Tuesday at 6:00 p.m. local time, but this time around, both a Pokémon and a special bonus will be featured! For each Pokémon Spotlight Hour, you can expect a different Pokémon and bonus.

• Tuesday, April 7, 2020: Purrloin will be in the spotlight, and you’ll earn twice the XP for catching Pokémon.
• Tuesday, April 14, 2020: Magnemite will be in the spotlight, and you’ll earn twice the Candy for catching Pokémon.
• Tuesday, April 21, 2020: Wobbuffet will be in the spotlight, and you’ll earn twice the Candy for transferring Pokémon.
