Pokémon GO Sableye Event: Spotlight Hours Recap
Spotlight Hours happen every Tuesday at 6 p.m. in your local time. For one hour, you'll be able to find the Spotlight Pokémon more easily. Besides the Spotlight Pokémon, you'll also get some other bonus for the hour.
Sableye's Spotlight Hour also gave double Candy for transferring Pokémon.
Unlike Community Day events, Spotlight Hours don't give you an increased chance of encountering a Shiny. Players use Spotlight Hours to hunt for a particular Shiny, but not many succeed. You're still fighting a one in 450 chance of getting a Shiny.
Spotlight Hours also don't introduce Shiny Forms, so you won't be able to find a Shiny of a Spotlight Pokémon if it's not available as so.
The Sableye event has come and gone, so be ready for the next Spotlight Hours event. Niantic has been announcing which Pokémon will have Spotlight Hours at the beginning of the month, so you can prepare to hunt for your favorites.
The next Spotlight Hour will feature Venipede, and the one after will have Geodude.
