Pokémon HeartGold & SoulSilver Cinnabar and Blaine Walkthrough
Meet Blue and defeat Blaine in Seafoam's Gym. Exact HGSS encounters, trainers, items, puzzle route, version differences, and completion checks.
Meet Blue and defeat Blaine in Seafoam's Gym. This combined guide never substitutes original Gold/Silver or Crystal data for the Nintendo DS remakes.
Source maps
Cinnabar Island, Seafoam Islands Cinnabar Gym.
Version scope
HeartGold and SoulSilver are labeled per row. Event-only and external-device content is never presented as normal retail progression.
Route Plan
Land on Cinnabar, speak to Blue to flag his later return, inspect the ruined island, enter the Seafoam Gym, defeat all trainers, then challenge Blaine's three Fire Pokémon.
Wild Pokémon
Each area below has its own table, split by encounter method. Standard rates merge every base slot for a species and are shown per time window: morning 04:00-09:59, day 10:00-19:59, night 20:00-03:59. Swarm, radio-broadcast, and Headbutt tables keep their own labeled rows, and every row carries HG/SS markers. Underlying slot odds: grass 20/20/10/10/10/10/5/5/4/4/1/1; Surf 60/30/5/4/1; Rods 40/30/15/10/5; Rock Smash 80/20; Headbutt 50/15/15/10/5/5.

Trainers
Teams are the exact source party records. Moves and held items appear only when the trainer format defines them. Reward = last party member level × 4 × trainer-class multiplier; double battles double the base payout where the engine applies it.
