Pokémon Go Sinnoh Throwback Challenge 2020 and research tasks explained

How 'Throwback Challenge 2020 Sinnoh' works in Pokémon Go

The Sinnoh Throwback Challenge works like the other Research quests that were introduced in March 2018, where players can complete various tasks for special rewards.

The Sinnoh Throwback Challenge is constructed out of eight quest steps, with each one referencing a Gym Leader from Pokémon Diamond, Pearl and Platinum. For completing the fifth set of challenges, for example, you'll be rewarded with a Drifloon encounter, because Fantina, the fifth Gym Leader in all three games, specialises in ghost-type Pokémon.

Unlike the recent paid-for quests in Pokémon Go, this event is free for all players. The catch, however, is that you only have a week to access and complete every challenge in the event.

'Throwback Challenge 2020: Sinnoh' dates and times in Pokémon Go explained

The Sinnoh Throwback Challenge is the fourth of five special Throwback Challenges running week-by-week from the beginning of May 2020.

'Throwback Challenge 2020: Sinnoh' is running between Friday, May 22nd to Friday, May 29th. It starts and ends at 1pm your local time on these days.

If you've already completed the Kanto, Johto and Hoenn Throwback Challenges from the previous weeks, then you should complete this final regional Throwback Challenge to unlock the final, 'Throwback Challenge Champion 2020' event from June 3rd to June 8th.

The Season of Rising Heroes is here! Currently the A Valorous Hero event is running, bringing with it Mega Pinsir and the A Valorous Hero special research quest. The new Grass and Gratitude quest allows you to catch a mythical Shaymin! A new Team Go Rocket quest - From The Shadows - has been released, along with a shake up of the Giovanni and Team Go Rocket Leaders lineups. As you continue your Pokémon Go adventure, make sure to battle in the new Go Battle League season. Don't forget to take a look at the Remote Raid Passes changes or, if you purchased it, work on the Masterwork Research: Wish Granted quest. Elsewhere, be sure to use Daily Adventure Incense for the chance of encountering Galarian Articuno, Galarian Zapdos and Galarian Moltres. This incense may also give you encounters with other rare Pokémon in Pokémon Go.
