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

Conditional slots 9 for 6 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
Caterpie	in the morning	3–4	50%
	during the day	3–4	35%
Metapod	during the day	4–5	14%
	in the morning	4	10%
Pidgey	during the day	2–4	50%
	in the morning	2–4	35%
Rattata	at night	3–4	40%
Hoothoot	at night	4	20%
Spinarak	at night	3	30%

The red marker is Route 30. 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.
