If you’re a Pokémon GO player aiming to complete your Pokédex, you’ve likely come across Pokémon that require special evolution items. One of the most coveted among these items is the King’s Rock, a rare and valuable evolution item that allows you to transform certain Pokémon into their advanced forms. But how exactly can you get your hands on a King’s Rock in Pokémon GO? Let’s dive into the best ways to find this elusive item in May 2025.
What Is King’s Rock in Pokémon GO?
The King’s Rock is an evolution item introduced in Pokémon GO that allows two specific Pokémon to evolve into their special forms:
- Slowpoke → Slowking (Requires 50 Slowpoke Candy and a King’s Rock)
- Poliwhirl → Politoed (Requires 100 Poliwag Candy and a King’s Rock)
But unlike standard evolution items like Candy, King’s Rock is much harder to come by. It’s a rare drop, which means players need to know the best methods to increase their chances of obtaining one.

How to Get King’s Rock in Pokémon GO (May 2025)
If you’re on the hunt for a King’s Rock, here are the most effective ways to get one:
1. Spin PokéStops and Gyms
The most basic method to obtain a King’s Rock is by spinning PokéStops and Gyms. Each time you spin one, there is a small chance you will receive an evolution item, including the King’s Rock. However, the odds are low—roughly 1%—so consistent spinning is key.
Tip: Aim to complete a daily streak of spinning PokéStops to increase your chances of getting a rare item.
2. Open Gifts from Friends
Another reliable method is opening Gifts from friends. These Gifts can randomly contain evolution items, including the King’s Rock. Keep your friend list active, exchange gifts daily, and open them to increase your chances.
Pro Tip: Maximize your chances by maintaining multiple active friends who send and open Gifts regularly.
3. Achieve Research Breakthroughs
One of the most consistent ways to earn evolution items is by completing Field Research tasks. If you complete one task each day for seven consecutive days, you will achieve a Research Breakthrough. This guarantees a random evolution item, which could be a King’s Rock.
Reminder: Complete one task per day to ensure you don’t miss the streak.
4. Participate in Special Events
Pokémon GO frequently hosts events where the drop rates of evolution items are increased, or where you can earn them through special challenges. For example, the current “Crown Clash” event (May 10-18, 2025) offers a higher chance of obtaining a King’s Rock by catching Slowpoke or completing event tasks.
Event Strategy: Make sure you’re active during the event and complete all event-specific challenges for a higher chance of earning a King’s Rock.
5. Complete Special Research Tasks
Occasionally, special research tasks—particularly those linked to limited-time events—can reward players with a King’s Rock. Keep an eye on your available tasks and prioritize those that offer rare items.
Quick Tip: Check the in-game news for announcements about new Special Research tasks.
How to Use King’s Rock in Pokémon GO
Once you’ve acquired a King’s Rock, you can use it to evolve specific Pokémon:
- Slowpoke to Slowking: Use 50 Slowpoke Candy and one King’s Rock.
- Poliwhirl to Politoed: Use 100 Poliwag Candy and one King’s Rock.
Remember, the King’s Rock is consumed when you use it, so if you want to evolve both Pokémon, you’ll need two King’s Rocks.
Why King’s Rock Is Important
King’s Rock isn’t just a collectible item—it’s essential for trainers who want to complete their Pokédex and collect all Pokémon evolutions. Slowking and Politoed are unique additions to your team, and having them can enhance your battle strategies, especially in PvP battles.
Tips for Collecting More King’s Rocks
If you’re serious about collecting King’s Rocks, follow these best practices:
- Spin PokéStops and Gyms daily: Maintain a streak for better odds.
- Maximize friend interactions: Exchange and open Gifts every day.
- Complete Field Research tasks daily: Don’t miss a single day for consistent Breakthrough rewards.
- Participate in special events: These often boost your chances.
- Check the in-game shop: Occasionally, special item boxes may include evolution items.
Final Thoughts
The King’s Rock is a rare and valuable item in Pokémon GO, but with the right strategy, you can collect multiple King’s Rocks to complete your Pokédex and evolve your favorite Pokémon. Whether you’re spinning PokéStops, opening Gifts, or tackling event challenges, staying active in the game is the key to success.
