Before even reaching Sabrina I was moments away from smashing my Gameboy against the wall in a blind fit of rage. For me at least, Saffron City Gym easily wins as the most frustrating gym puzzle in a Pokémon game, period. Scattered across the floor are a number of warp squares, which must be stood on in particular order to be able to reach Sabrina. Sounds easy enough, but getting lost is a certainty, as all of the switches look the same and trainer battles only work to distract you. Sabrina proves to be especially difficult, as back in Generation 1, the only type of moves that were super effective to psychic Pokémon were bug-type. Alakazam is the toughest of the pack, dishing out the destructive psybeam and cowardly using recover when nearing its last inch of health. Venemoth can also make things a disaster, startling your Pokémon with stun spore and unleashing powerful psychic attacks.
