Brain Puzzle 3 Level 57

Overview

Level 57 is a resource-gathering forging puzzle. The banner reads "Forge a sword long enough." In a blacksmith's workshop, a blonde knight in silver plate armour and a red cape declares "The princess has been taken. I need a weapon." A dwarf smith sits at the anvil with a hammer. Hanging on the wall is a sword outline blueprint that starts as only a short black silhouette; as you feed metal into the forge, the silhouette fills in silver from the hilt toward the tip. The room is full of metal: an ingot on a shelf, a treasure chest, a suit of armour on a stand, hanging blacksmith's tongs, pliers, scissors, a horseshoe, a rack of small swords, and a pile of scrap metal. The goal is to lengthen the sword until the whole blueprint is filled in.

Step-by-Step Solution

1. Read the blueprint. The wall shows the target sword length. At the start only the outline exists; each piece of metal you add fills more of it silver. You are not done until the entire blade is filled.

1. Throw the rack of small swords into the forge. The wooden rack on the left holds several small blades. Toss them in as raw material; the blueprint starts filling.

1. Melt down the tools and horseshoe. The tongs, pliers, scissors and horseshoe hanging on the wall are all steel. Feed them to the anvil to add more length. They disappear from the wall as the blade grows.

1. Use the metal ingot and the scrap pile. The ingot on the shelf and the heap of scrap metal on the floor both go into the fire, extending the sword further.

1. Break open the treasure chest. The chest on the shelf opens (red interior) and its valuable contents are melted in as well — the caption notes "This material is extremely valuable," but it is needed for length.

1. Strip the suit of armour off the stand. The display armour is metal; take its plates off and forge them in. The stand ends up with only a spare arm piece left.

1. Take off the knight's own armour. When the room's metal is not quite enough, the knight removes his own plate armour and adds it to the sword. By the later frame he is down to a white tank top and pink shorts, barefoot, while the blade on the anvil stretches the whole length of the room.

1. Wait for the completion. Once the blueprint is fully filled, the scene cuts to the knight standing on a defeated golden dragon in a cave, holding an enormous sword, with the rescued princess beside him, and "Completed" appears.

Strategy & Reasoning

The puzzle is a "how long is long enough?" resource trick. The blueprint on the wall is a progress bar: every metal object you commit fills in more of it. At first you only think of obvious raw material (the ingot, the scrap), but the blade is still short, which forces you to get creative — melting down the smith's own tools, the display armour, the treasure chest, and finally the knight's own plate. The punchline is that he ends up forging his own armour into the weapon, which is why he arrives at the dragon fight in just a tank top and shorts.

The reason you cannot just use one big piece is that the target length is deliberately exaggerated — the finished sword in the victory shot is comically enormous, reaching to the ground. So every scrap of metal in the room is required. The chest and armour are the non-obvious sources, and the "extremely valuable" caption is a joke: the gold must be sacrificed for the mission.

Tips & Common Mistakes

• Mistake: stopping once the sword looks long enough. Watch the wall blueprint, not the blade on the anvil. The sword is only finished when the entire silhouette is filled silver.
• Mistake: forgetting the tools and the armour. The hanging tongs/pliers/scissors/horseshoe and the display armour are all metal and all get melted in. If they are still hanging on the wall, the sword is not done.
• Mistake: leaving the knight in his armour. His own plate is the final batch of material. He has to strip down to his undershorts before the blade reaches the required length.
