Guide by LevelWalks
Level 42 lands in Brain Test: Tricky Puzzles's mid-tier band, and most players who Google it are stuck not because the answer is hard, but because the puzzle frames the question in a way that sends you down the wrong path.
## Question
**Brain Test Level 42:** Make this equation correct: 5+5+5=550
## Answer
Add a single line to one of the + signs to make it a 4. So 545+5=550.
## Step-by-Step Walkthrough
Draw a small diagonal line on the first + sign to turn it into a 4. The equation becomes 545+5=550, which is correct. This is a classic matchstick-style puzzle.
Here is exactly how to solve Brain Test Level 42:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Add a single line to one of the + signs to make it a 4.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Brain Test Level 42 is designed to catch players who think too literally or too logically. The game's core mechanic is to subvert expectations. Most players fail this level on their first try because they approach it with conventional thinking. The key insight is that the game often uses the question text, physical phone gestures, or visual misdirection as part of the puzzle. Once you understand that Brain Test breaks the fourth wall regularly, these puzzles become much more manageable.
## Why This Level Is Tricky
Mid-difficulty Brain Test levels exploit cognitive biases — anchoring, framing effects, and confirmation bias all play a role. The puzzle is engineered so your first instinct leads you astray. Recognizing which bias the level targets is half the battle. These early levels (1-50) teach you Brain Test's fundamental trick vocabulary: literal wordplay, tapping hidden elements, and questioning obvious answers. Master these patterns now — they recur throughout the entire game.
## Common Mistakes
Players frequently make these errors on Level 42:
- Fixating on the visual scene and ignoring the question text, which often contains the key wordplay or clue.
- Trying the same approach repeatedly instead of testing a completely different interaction method.
- Forgetting that some levels require physical phone actions — shake, tilt, rotate, or cover the camera.
Tips
- Don't overthink it — Brain Test rewards creative, lateral thinking over logical analysis.
- If your first instinct doesn't work, try the opposite approach — Brain Test loves to subvert expectations.
- Remember: Brain Test Level 42 has a difficulty rating of 3/5 — expect a moderate challenge requiring creative thinking.
