Do I need to trade to finish Pokemon Yellow?
Story answer: no. Credits and the Champion do not require a second cart. Pokédex answer: it depends—diploma 150 and a living set pull in NPC trades, one-save choices, and link-trade gaps. Pick your goal below for a direct verdict.
Fast answer
Finish ≠ fill the dex
If “finish” means beat the game, play solo. If it means diploma 150 or a living dex, plan link trades—Yellow’s gap list leaves a solo cart short of 150 owned.

Side by side
Three definitions of “finish”
Champion credits
Badges, Victory Road, Elite Four, Rival. Any legal solo team works—see no-trade team and Elite Four tools.
Diploma 150
Owned-count goal in Celadon Mansion. Mew not required, but gap families still force link trades (or glitches) to reach 150 owned.
Living completeness
All families, trade evolutions, both Dojo fighters, both fossils, three Eeveelutions—plan a link partner or multi-save logistics.
Link-trade gap list
Species flagged trade-required
These entries are marked trade-required in the site’s Yellow availability data. Story mode can ignore them entirely.
Trade evolutions
Link vs NPC
Machamp — solo OK
Trade Cubone to the in-game NPC for Machoke; it evolves into Machamp as part of that exchange. No second cartridge required.
Alakazam · Golem · Gengar
Kadabra, Graveler, and Haunter need a link trade to evolve. Keep a stone/copy plan if you want both stages.
Raichu special case
Partner Pikachu refuses the Thunder Stone. A Raichu for the dex needs a non-partner Pikachu or a traded Raichu.
One-save permanent choices
Not always “trade,” but still a second mon problem
Practical plan
Recommended order
1. Solo the story
Ignore trades until Champion. Use gift starters, Nidoking routes, and Lapras for coverage.
2. Sweep NPC trades
Pick up Mr. Mime, Dugtrio path, Cubone→Machamp, and the rest while you still visit those cities.
3. Count owned for diploma
Push toward 150 with wild lines, fossils, legendaries, and gifts. Open Catch Planner + Pokedex trackers.
4. Schedule one link session
Only if you want living completeness: gap families, Alakazam/Gengar/Golem, extra Dojo/fossil/Eevee branches.

FAQ
Trade questions
Do I need to trade to finish Pokemon Yellow?
No for the story. Yes if “finish” means a full living Pokédex with every family and trade evolution.
Can I get the diploma alone?
Mew is not required, but solo Yellow cannot reach 150 owned while the trade-gap families remain missing. Maximize NPC trades and solo sources, then link trade the gap list—or use glitch methods if you accept the risk.
Does the game force a trade evolution?
No story boss requires Alakazam, Gengar, or Golem. They are optional. Machamp is the convenient solo trade evolution via NPC.
What about glitches instead of trading?
Glitch encounters can create otherwise missing species, including Mew setups. They are optional, version-sensitive, and risky for saves—see the Mew and glitch guides if you choose that route.
