Brain Test 5 Level 85
📝 Walkthrough
Overview
This is a cave-door puzzle spread across five notebook pages. The page reads "Open the door." and shows a stone arched cave door with directional arrows painted on it. Three torches are mounted on the walls around the door, and a pickaxe lies on the ground. A pirate character peeks out of a hole on the left, and rocks are scattered around the cave floor. Later rounds introduce a bomb, a dark monster, and a dragon that must be avoided while opening the door. The overall approach is to use the torches and available tools to unlock or blast open the cave door safely.

Step-by-Step Solution
- First, look at the arrows on the door. They show directions: left, right, up, and down. This indicates you need to slide or push the door in a specific sequence. Try dragging the door in the direction of the arrows in the order they appear.
- If the door will not slide, use the pickaxe on the ground. Drag the pickaxe over to the door edges and chip away at the stone around the frame. This loosens the door so it can be pushed open.
- On later rounds where a bomb is available, place the bomb next to the door and light it with one of the torches. Step back and let the explosion blast the door open.
- Watch out for the dark monster and the dragon. The monster hides in dark corners — make sure all torches are lit before you approach, so the monster cannot surprise you. The dragon breathes fire, so time your door opening between its fire bursts.
- If the door is blocked by a boulder, roll the boulder out of the way first, then work on the door itself.
- Once the door swings open, a green checkmark appears to confirm you have opened it successfully.
Strategy & Reasoning
The puzzle is about using the environment. The torches are not just decoration — they provide light (keeping the monster away) and can also light a bomb. The pickaxe is for loosening stone. The arrows on the door hint at the opening mechanism: the door slides in the arrow directions.
The optimal strategy is to first light all torches, then use the pickaxe to loosen the door, then slide it open. If a bomb is available in later rounds, that is a faster method but must be timed carefully to avoid the dragon's fire. Alternatives like pushing the door directly fail because the stone is too heavy and stuck.
Tips & Common Mistakes
- Do not approach the door in the dark; the monster hides in unlit corners. Light all torches first.
- Do not push the door without loosening it with the pickaxe; the stone frame holds it in place.
- Do not stand too close when lighting a bomb; the explosion can hurt you if you are nearby.
