Side Quests & Mini-Games
The big side quest is the Biggoron Sword trading sequence — about 10 trades as adult Link, several of them timed, ending in the unbreakable Biggoron's Sword (start by talking to Anju in Kakariko). The other big rewards come from the Great Fairy fountains (the three Din/Farore/Nayru spells plus magic and defense upgrades) and the mini-games that pay out Heart Pieces and quiver/bag upgrades.

Biggoron Sword trading sequence
This is the longest fetch quest in the game and the only way to the strongest sword. Do it as adult Link; once the timed trades start, keep moving and use Epona between regions.
⚠️ The timer rules
The trades from the Odd Mushroom onward are on a real countdown — if you take too long the item spoils and you have to fetch it again. Plan your route before you grab each timed item, and use warp songs plus Epona to shave the trips. The Eye Drops run up Death Mountain is the tightest.
Great Fairies
Smash the entrance with a bomb (or play Zelda's Lullaby) at a fountain and the Great Fairy grants a spell or a permanent upgrade. These are the main source of your active magic abilities.
Din's Fire
Great Fairy near Hyrule Castle — ring of fire, lights torches
Farore's Wind
Zora's Fountain (behind Jabu-Jabu) — dungeon warp point
Nayru's Love
Desert Colossus — invincibility barrier
Magic Meter / Double Magic
Death Mountain Crater & Ganon’s Castle fairies — upgrade magic
Double Defense
Hyrule Castle fountain (as adult) — halves damage taken
💡 Great Fairy not appearing?
If nothing happens at a fountain: the spell fountains open when you play Zelda's Lullaby on the Triforce mark, while the upgrade fountains (Death Mountain, Ganon's Castle) need you to bomb the cracked wall first. You also can't get a spell you already have — the fountain only triggers for an upgrade you haven't claimed.
Mini-games & rewards
Most mini-games hand out a one-time Heart Piece and an equipment upgrade. Here's what each gives and where to play it.
