Data from Pokemon SoulSilver only: exact levels and the encounter rate for each Pokémon.

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.

Pokémon	Conditions	Level	Rate
Spearow	in the morning	14–16	25%
	during the day	14–16	25%
	radio off, in the morning	14	10%
	radio off, during the day	14	10%
Zubat	at night	14–16	25%
	radio off, at night	14	10%

The red marker is Route 42. 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
• 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.
