1 Celadon Game Corner jackpot
The single best value stop in the game. First grab the Coin Case from a man near the Game Corner, then win/buy coins and cash them in.
Prize Pokémon
| Pokémon | Coins | Why |
|---|---|---|
 Abra | 180 | Cheap → trade for another Alakazam |
 Clefairy | 500 | Moon Stone → Clefable |
 Dratini | 2,800 | → Dragonite, a top-tier powerhouse |
 Scyther (FR) | 5,500 | Fast Bug/Flying; → Scizor via trade. LeafGreen offers Pinsir here instead — see Versions |
 Porygon | 9,999 | Rare collector's mon; solid special attacker |
Prize TMs
The prize counter also sells the moves that make your team: TM13 Ice Beam, TM24 Thunderbolt, TM35 Flamethrower, TM30 Shadow Ball (plus Iron Tail, Reflect). These power Nidoking, Lapras, Alakazam, Raichu & Charizard — see Dream Team. Priority buys: Ice Beam + Thunderbolt (they go on multiple mons).
2 Eevee & the eeveelutions
A free Eevee waits on the rooftop of the Celadon mansion (from the Pokémon Center, go right & up through the trees, into the building's back door, climb to the roof — Poké Ball on the table). Pick your evolution with a stone:
Thunder Stone. Blazing speed, big Sp.Atk. The pick if you want to out-class Raichu.
Water Stone. Huge HP tank; Surf/Ice Beam. Great if you skip Lapras.
Fire Stone. Monster Attack — but a shallow physical-Fire movepool in Gen 3. Cool, not optimal.
3 Free fighter — the Saffron Dojo
Clear the Fighting Dojo (top-right of Saffron) and the Karate Master lets you take one for free:
Hitmonlee
High Attack, Hi Jump Kick
Hitmonchan
Elemental punches, bulkier
Which to pick?
Hitmonlee for raw offence (its Attack is enormous). Hitmonchan if you like coverage (Fire/Ice/Thunder Punch).
Neither makes the core six here, but both are strong Fighting options and a free catch for the Pokédex.
4 Fossil revivals
Ancient Pokémon you revive at the Cinnabar Pokémon Lab. You can only choose one of the Mt. Moon fossils per game — the other needs a trade.
Old Amber — back room of the Pewter Museum. Fastest revival; Rock Slide/EQ/Fly. best of the three
Dome Fossil — pick at Mt. Moon. Strong physical Attack.
Helix Fossil — the other Mt. Moon choice. Great Sp.Atk/Def; Surf/Ice Beam.
5 The elemental move tutor starter buff
On Cape Brink (Two Island) in the Sevii Islands, a house holds a tutor who teaches your fully-evolved starter its ultimate 150-power move — once. Which one depends on your starter:
- FireBlast Burn — Charizard
- WaterHydro Cannon — Blastoise
- GrassFrenzy Plant — Venusaur
It needs a recharge turn, so it's a finisher rather than a spam move — but it hits like nothing else. There are more one-time tutors scattered across the Sevii Islands (e.g. Double-Edge, Body Slam, Thunder Wave, Explosion). Save these for a Pokémon that'll keep the move for good.
6 Trade evolutions
Four Kanto Pokémon only evolve when traded. If you have a link partner (or a second game/console), these unlock some of the strongest mons available:
| Trade this | Get | Where to catch the base |
|---|---|---|
| Kadabra |  Alakazam | Catch a wild Abra (Routes 24/25, 5–8) → Kadabra |
| Machoke |  Machamp | Machop: Rock Tunnel, Route 10 |
| Haunter |  Gengar | Gastly/Haunter: Pokémon Tower, Lavender |
| Graveler |  Golem | Geodude/Graveler: Rock Tunnel, Victory Road |
7 Master Ball & key items
Master Ball
Given by the Silph Co. President (11F) after you beat Giovanni there. It's a guaranteed catch — save it for Mewtwo (Lv 70, hardest catch) or the roaming Suicune (which flees every turn and is a nightmare with normal balls).
Rare Candies & hidden items
Rare Candies (instant level) are hidden all over — Rocket Hideout, Silph Co., Victory Road, the Sevii Islands. Use them on your slowest-to-level team member (Dragonite/Snorlax). Many hidden items sit on invisible tiles — an Itemfinder (from Oak's aide on Route 11 at 30 caught) beeps near them.
