Brain Test Level 143 Walkthrough & Answer
Level 143★★★★★
Guide by LevelWalks
When I ran through Brain Test: Tricky Puzzles myself, Level 143 was one of the puzzles where I had to put the phone down and think for longer than I wanted to admit. The walkthrough below is what I worked out, plus the reason the trick works.
## Question
**Brain Test Level 143:** Which is the longest line?
## Answer
Scroll right — there's a very long line extending beyond the visible screen area.
## Step-by-Step Walkthrough
Three lines of different lengths are shown. They look like typical comparison options, but scrolling or dragging the screen to the right reveals that one line extends far beyond the visible area. That's the longest.
Here is exactly how to solve Brain Test Level 143:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Scroll or drag the screen to the right — one line extends far beyond what's initially visible.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Bounded perception means you assume the screen edges define the puzzle's boundaries. Brain Test loves hiding elements just off-screen. The lesson: always check beyond the visible frame before committing to an answer.
## Why This Level Is Tricky
At this difficulty, Brain Test expects multi-step thinking. Break the puzzle into parts: what does the question ask, what elements are on screen, and what interactions haven't you tried yet? Combine objects, drag text, or use multiple fingers simultaneously. Systematic experimentation beats random tapping. Mid-game levels (51-150) start combining multiple trick types in one puzzle. You might need both wordplay and physical interaction to solve a single level. If one approach fails, switch to a completely different trick category.
## Common Mistakes
Players frequently make these errors on Level 143:
- Overthinking a simple puzzle — sometimes the answer is literally what the question says, with no trick at all.
- Not trying to drag or resize on-screen elements, including text, images, and answer options.
- Missing that Brain Test sometimes reuses a trick from an earlier level with a slight variation.
Tips
- Scroll or drag the screen to check for hidden elements beyond the visible area.
- Look at negative space, shadows, and object arrangements for hidden patterns.
- Remember: Brain Test Level 143 has a difficulty rating of 3/5 — it challenges your assumptions.
