How Pokémon Let's Go Catch Rates Work

Catching Pokémon in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! differs significantly from the core series. Instead of battling, the mechanics rely on modifiers that stack to increase your success percentage.

Key Modifiers Explained:

  • Base Catch Rate (BCR): Each species has a hidden number. Common Pokémon like Pidgey have high BCRs, while Legendaries have a BCR of 3.
  • The Level Penalty: As a Pokémon's level increases relative to your progress, the "Level Multiplier" makes them harder to catch.
  • The Ring Bonus: Timing your throw so the ball hits inside the colored circle provides a multiplier: Nice (1.2x), Great (1.5x), or Excellent (2.0x).
  • Support Bonus: Using a second Joy-Con to throw two balls simultaneously significantly boosts your odds and provides a "Sync" bonus.

Pro Tips for Shiny Hunting:

When going for a 31+ Catch Combo, your catch rate for that specific species increases. Combining a 31+ Combo with a Golden Razz Berry and an Ultra Ball is the most effective way to secure rare spawns and Shiny Pokémon without them fleeing.
