Conditional slots 17 for 10 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.

	in the morning	18	4%
	at night	18	4%

The red marker is Route 10. 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
• Interior — cave, forest, tower; placed next to its entrance
• Path between places
• Path that requires Surf
• Entrance to an interior — not a passage to the other side

Directions read from the map layout in the games — from how the screens connect to each other. We know them for Kanto, Johto, Hoenn and Sinnoh; in other regions you will not see this section, because we have no source for the topology.
