Wild Pokemon

Version

Each area below has its own table, split by encounter method. Red/Blue has no time-of-day mechanic, so every method uses a single rate column, and the R/B chips show which version each row applies to. Tall grass, cave, and Surf rates merge every base slot for a species out of the Gen I ten-slot table: 51/256, 51/256, 39/256, 25/256, 25/256, 25/256, 13/256, 13/256, 11/256, and 3/256. Fishing, gift, trade, prize, and static rows keep their own labeled rates.

Completion Checklist

  • Collect the Moon Stones and TMs.
  • Defeat the Super Nerd guarding the fossils.
  • Choose Dome Fossil for Kabuto or Helix Fossil for Omanyte.
  • Verify the wild table's version splits before leaving if you are filling the Pokedex.
  • Use the item rows as a visible-item and hidden-item sweep before moving to the next section.

Sources

  • pret/pokered: wild encounters, trainer parties, trainer money, map object events, hidden event items, rods, trades, and prize Pokemon.
  • Encounter odds aggregate the Gen I ten-slot rates: 51/256, 51/256, 39/256, 25/256, 25/256, 25/256, 13/256, 13/256, 11/256, and 3/256.
