Brain Test 5 Level 63

Overview

This is a multi-puzzle level spread across three notebook pages. One page presents a number-sequence puzzle where rows count up by one (4-5-6 and 5-6-?, so the missing number is 7). Another page reads "She must find the safe door." and shows a cave interior with four doors: a smoking door on the left, a door with a vampire peeking out, an open door in the middle, and an ice-covered door on the right. A girl explorer with goggles stands in the middle-right entrance. The overall approach is to deduce which door is safe by eliminating the obviously dangerous ones, then guide her through it.

• Difficulty: Easy
• Estimated moves: 4

Step-by-Step Solution

1. On the number-sequence page, look at the rows. The first row goes 4-5-6, counting up by one. The second row goes 5-6-?, which means the next number is 7. Tap or fill in the number 7 to complete the sequence.
2. On the cave page, examine each door one by one. The left door has smoke coming out of it, which means fire or dangerous fumes inside. The middle-left door has a vampire face peeking out, which is clearly dangerous. The right door is covered in ice, which means extreme cold or a frozen trap.
3. The middle door is open and shows nothing scary inside. This is the safe door. Guide the girl explorer through this door by dragging her toward it or tapping the door to send her through.
4. If you tap the wrong door, the girl will react negatively (a red X appears). You have five attempts at the top of the page, so use them carefully.
5. Once she walks through the correct safe door, a green checkmark appears and the level advances.

Strategy & Reasoning

The number page is simple pattern recognition: each row increments by 1. The trap is overthinking it — some players look for a multiplication or subtraction pattern, but it is just counting. The answer 7 follows directly from the pattern.
The cave page works by elimination. Three doors are obviously unsafe: smoke means fire, a vampire means a monster, and ice means a frozen trap. Only the middle door is clear and open. The optimal strategy is to quickly identify the danger signs and skip straight to the safe door. Alternatives like trying to move the vampire or blow out the smoke do nothing; you must choose the right door, not fix the bad ones.

Tips & Common Mistakes

• Do not overthink the number sequence; it is simply counting up by one in each row, and the answer is 7.
• Do not choose the ice door just because it looks pretty; it is a frozen trap and just as dangerous as the vampire door.
• Do not waste time tapping the smoking door; the smoke is a clear fire warning and there is no way to put it out from the outside.
