Kanto route, story keys and HM travel
Connect Kanto's major story gates with Cut, the Silph Scope, the Poké Flute, Surf and Strength in original Red/Blue.
International Game Boy Red and Blue, released in 1998 in North America and Australia and 1999 in Europe. The series began with Japanese Red and Green in 1996; the international pair uses revised graphics from Japanese Blue. Yellow, FireRed/LeafGreen and Let's Go have different encounters or mechanics. Cartridge linking uses a Game Link Cable; the 3DS Virtual Console editions use local wireless.
Open Vermilion's route with Cut

Cerulean City: map or interior assembled from original Red/Blue game graphics; the source sheet may include Super Game Boy palettes. .
After Cerulean, visit Bill to receive the S.S. Ticket and continue south to Vermilion City. Help the S.S. Anne's captain to obtain HM01 Cut. A compatible Pokémon must learn the move, and Misty's Cascade Badge permits its field use. Use it on the tree blocking Vermilion Gym. An HM and permission from a badge are separate requirements, so check both when a move appears available but does not work outside battle.
Resolve the ghost and sleeping-Pokémon gates

Celadon City: map or interior assembled from original Red/Blue game graphics; the source sheet may include Super Game Boy palettes. .

Rocket Hideout: map or interior assembled from original Red/Blue game graphics; the source sheet may include Super Game Boy palettes. .
The Celadon Rocket Hideout supplies the Silph Scope, which identifies the ghosts in Lavender's Pokémon Tower. Rescuing Mr. Fuji there earns the Poké Flute, the key to waking the blocking Snorlax. The international originals open Saffron's guard posts with a drink bought from Celadon's rooftop vending machines. Follow these small errands before searching every surrounding route; a missing story item can be the actual reason the path remains closed.
Use the Safari Zone trip for two travel tools
Fuchsia's Safari Zone contains the Secret House that awards Surf and the lost Gold Teeth. Return the teeth to the Warden to receive Strength. Koga's Soul Badge enables Surf in the field, while Erika's Rainbow Badge enables Strength. Check the zone's remaining steps while exploring, and plan another visit if necessary. Surf opens sea routes toward Cinnabar; Strength also matters in caves where boulders block the way.
In Red/Blue an HM move cannot be forgotten through the ordinary move-learning prompt. Decide which teammate will carry it before teaching it.
