in tall grass

Conditional slots 11 for 7 species — time of day, weather, radio and other switches

The game keeps these slots separate from the base ones. Condition sets exclude each other (it cannot be morning and night at once), and the source does not say whether a condition adds a slot or replaces the whole table — so we list them row by row instead of adding them to the rate on the tile.

The red marker is Route 221. A diagram, not a world map — distances are not to scale, but directions and connections match the game. The legend below the drawing explains each symbol.

• Route — number inside
• Sea route — Surf only
• City
• Pokémon League
• Landmark — lake, forest, facility
• Path between places
• Path that requires Surf

Generation IV does not store connections directly — it keeps the world as a grid, which only tells us that these places share an edge. So the adjacency is certain, the passage itself is not: a river, a rock or a height difference may separate them.
