How to evolve Tyrogue into Hitmontop, Hitmonlee or Hitmonchan

In the core game series, Tyrogue evolves into one of its’ three forms based on it’s highest stat. The same behaviour has been confirmed in Pokémon GO.

According to a research done by DrWolfenstien of TheSilphRoad fame, Tyrogue’s evolution is entirely dependent on its highest stat.

Highest Stat
Attack Stamina Defense

 

Any ties in stats will be a random choosing of the tied outcomes. That being said, ties between Attack/Stamina or Defense/Stamina tend to lean towards Lee and Chan respectively.

A combination of all three is a little more evenly distributed. You can figure out the highest stat by using the in game Appraisal.
