Zelda 1 - Walkthrough of Dungeon 9 of Quest 2: Ganon's Head (Zelda I NES mini)
Map of the labyrinth "Ganon's Head": Dungeon 9 of Quest 2 from Zelda I (The Legend Of Zelda NES mini)

Nothing new in this level except the relatively large number of dead ends that you won't fall into thanks to my walkthrough. If you are stuck in the second room, it means you don't have all the Triforce pieces.

Go up twice and walk through the right wall twice. Then make a hole at the top while avoiding (or killing) the Wizzrobes. Go left through the wall and kill all the Wizzrobes.

Push the stone to reveal a passage and take it to find the silver arrow that will allow you to kill Ganon. Go back out and walk through the right wall. Kill Patra to get the map and return to the room with 2 flames just above the start. Go left and kill the 2 blue Lanmolas (the centipedes) to continue further left.

Continue left and go up twice to reach B5. Push the block and blow up the left wall. Go through the hole and come back into the room to be able to push the block again, then go up.

Go right and blow up the bottom wall, then kill all the black Zols to get the compass. Go back up and blow up the top wall to be able to go upward (without killing the Wizzrobes, who would only give you a key).

Go right then up, then follow the sage's advice by walking through the left wall. Continue left and go up, then walk through the left wall while avoiding Patra. Kill the 2 Lanmolas, push the left block, go pick up the red ring and walk back through the right wall.

Kill Patra to be able to push the block and take the passage that brings you to the right side of room F2. Blow up the right wall with a bomb, then kill Patra and continue right to come face to face with Ganon.

As soon as you enter the room, Ganon (Gannon) disappears. Strike randomly everywhere to hit him. After 4 hits (he appears when struck), Ganon turns brown (3). You must then pierce him with a silver arrow to reduce him to a pile of dust and collect his Triforce.
