Haunter does not evolve into Gengar at a certain level. Haunter needs to be traded to another player. Once he is traded, he will evolve.
Gastly evolves into Haunter at level 25, then trade it and it will evolve again into Gengar.
Haunter will evolve into Gengar when it is traded. It doesn't matter what level it is, just trade it with someone and when they get it it will evolve into Gengar, then get them to trade it back to you.
Haunter does NOT evolve by level. You evolve Haunter by trading it with a friend, and then they trade it back to you. Hope I helped :)Haunter evolves from Gastly at level 25.Haunter evolves into Gengar through trade.Haunter evolves into Gengar by trading it.
