Brain Test Level 139 Walkthrough: Swipe the shape to dismantle it and enter 5
Complete Guide • Step-by-step explanation • Common mistakes
🧩 Level Information
- Level Number: 139
- Question: Swipe the shape to dismantle it and enter 5
- Difficulty: Medium
🎯 Objective
Swipe the shape in the center of the screen to dismantle it, and enter the number "5" of the pieces that appear to clear the level.
📝 Steps to Solve
- Focus on the single shape (a block-like picture) in the center of the screen. At first, it looks like a single mass.
- Swipe the shape quickly to either side with one finger (not dragging but a swift flick-like motion).
- If swiped correctly, the shape will break into separate pieces. Count the number of separated pieces.
- Ensure that the dismantled pieces total 5.
- Tap the answer field (number input field) below and enter "5".
- After entering, tap the OK button or check mark to confirm your answer and clear the stage.
💡 Hints
- Think about whether the shape can be 'moved or broken' instead of just counting it as is.
- Instead of just tapping the shape, why not try tracing or swiping it with your finger?
- Swiping quickly over the shape will make it break into pieces. Count the number of scattered pieces and input that number. The answer is 5.
🧠 Explanation & Key Points
This stage is a type of puzzle designed to break the assumption of trying to answer based only on visible information. Initially, a single shape is visible, and in its unaltered state, the number cannot be deduced, but by swiping the shape, the internal structure (pieces) is "exposed." The key point is whether the player can arrive at the notion that 'the shape might be movable or breakable.' In Brain Test, it’s common to 'touch, swipe, or reveal' hidden elements in pictures, and understanding this convention makes it easier to notice. The final logic is simple — count the dismantled pieces→5 pieces→enter "5," but noticing the 'dismantling operation' beforehand is what makes it challenging.
🔍 Common Mistakes
- Looking at the shape as is and arbitrarily entering a number (trying smaller numbers like 3 or 4).
- Only trying to press and hold or drag the shape without trying the swipe action.
- Failing to count the dismantled pieces accurately and entering a number based on estimation, resulting in a wrong answer.
- Not reading the instruction 'Swiping to dismantle' carefully and mistakenly thinking it’s a regular arithmetic problem.
🎉 Advice After Clearing
If you realized the shape can be dismantled, it turns out it was a simple task of just counting, something that can be reaffirmed in Brain Test: the importance of thinking not only to 'just look' at a picture but also to 'touch, trace, and break' it.
