Evolving Porygon in Pokémon GO requires specific items and a good amount of Porygon Candy. Here’s a detailed guide to help you evolve Porygon into Porygon2 and Porygon-Z.

Step 1: Gathering Porygon Candies
To start, you’ll need to collect Porygon Candies. You need 50 candies to evolve Porygon into Porygon2 and an additional 100 candies to evolve Porygon2 into Porygon-Z. Candies can be collected by catching Porygon in the wild, using Pinap Berries to increase the candy yield, walking with Porygon as your buddy, and transferring extra Porygon to Professor Willow.
Step 2: Acquiring an Upgrade
The Upgrade item is required to evolve Porygon into Porygon2. You can obtain an Upgrade by spinning PokéStops and Gyms, although the drop rate is around 1%. Another way is by maintaining a seven-day spinning streak, which guarantees an evolution item, though it might not always be an Upgrade. Participating in special events like Community Day can also increase your chances of getting an Upgrade through Timed Research tasks.
Step 3: Evolving Porygon into Porygon2
Once you have 50 Porygon Candies and an Upgrade, select the Porygon you wish to evolve. Use the in-game appraisal feature to choose a Porygon with strong stats for the best results. Then, tap the ‘Evolve’ button to transform your Porygon into Porygon2.
Step 4: Obtaining a Sinnoh Stone
To evolve Porygon2 into Porygon-Z, you’ll need a Sinnoh Stone and 100 Porygon Candies. Sinnoh Stones can be obtained through several methods:
- Participating in the GO Battle League
- Training with Team Leaders (Candela, Blanche, and Spark)
- Defeating Team GO Rocket Leaders
- Battling friends in PvP matches
- Completing seven-day Research Breakthrough tasks.
Special events and Timed Research tasks during events like Community Day can also reward you with Sinnoh Stones.
Step 5: Evolving Porygon2 into Porygon-Z
After collecting 100 Porygon Candies and a Sinnoh Stone, select the Porygon2 you want to evolve. Again, it’s wise to choose one with the best stats. Tap ‘Evolve’ to transform Porygon2 into Porygon-Z.
Tips for Efficient Evolution Item Collection
- Maximize PokéStop and Gym Visits: Frequent visits to PokéStops and Gyms increase your chances of getting evolution items. Plan routes with multiple PokéStops and Gyms.
- Maintain Daily Spinning Streaks: A seven-day spinning streak guarantees an evolution item. Prioritize maintaining this streak.
- Engage in PvP Battles and GO Battle League: These activities not only hone your battling skills but also offer chances to earn Sinnoh Stones.
- Complete Team Leader Training: Training with Team Leaders can reward you with Sinnoh Stones.
- Stay Alert for Special Events: Events often provide specific items as rewards, such as Upgrades and Sinnoh Stones. Keep an eye on the game’s news section for upcoming events.
- Battle Team GO Rocket Leaders: These battles are challenging but can yield Sinnoh Stones.
- Trade with Friends: If you have friends who play Pokémon GO, consider trading items. Some might have spare Upgrades or Sinnoh Stones they’re willing to trade.
By following these steps and tips, you can efficiently evolve your Porygon into Porygon2 and then into Porygon-Z, adding these powerful forms to your Pokémon GO collection.
