Brain Test Level 245 Walkthrough & Answer
Level 245★★★★★
Guide by LevelWalks
If Level 244 of Brain Test: Tricky Puzzles felt routine, Level 245 is the kind that breaks the pattern. The devs schedule these on purpose — usually right where players start solving on autopilot.
## Question
**Brain Test Level 245:** Measure the length of the line using the ruler
## Answer
Drag the ruler to align with the line, but start from 0, not the edge. The ruler starts at 1cm, not 0.
## Step-by-Step Walkthrough
A ruler and a line are on screen. Drag the ruler to the line, but make sure the 0 mark (not the ruler's edge) aligns with the line's start. The common mistake is measuring from the ruler's edge, which adds extra length.
Here is exactly how to solve Brain Test Level 245:
1. Read the question carefully — Brain Test loves wordplay and misdirection.
2. Look at every element on screen, including the question text itself.
3. Align the ruler's 0 mark with the start of the line, not the physical edge of the ruler.
4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers.
## Why It's Tricky
Ruler-edge-as-zero is a common measurement error, even in real life. Brain Test deliberately makes the ruler's 0 mark offset from its physical edge. This tests metrological literacy — a skill most people learn but don't practice carefully.
## Why This Level Is Tricky
For difficulty 4, expand your toolkit: try shaking the device, using the volume rocker, covering the camera, or pressing the home button area. Also try dragging seemingly static elements like the level number, score display, or hint button. Brain Test treats everything on screen as a potential puzzle piece at this tier. Late-game levels (151-300) frequently require device interaction — tilting your phone, using multiple fingers, shaking the device, or manipulating screen elements outside the puzzle area. Think beyond the touchscreen for these multi-step solutions.
## Common Mistakes
Players frequently make these errors on Level 245:
- Tapping the most obvious on-screen element without reading the full question first.
- Ignoring the question text as a potential interactive element — in Brain Test, words on screen can often be dragged, tapped, or used as part of the solution.
- Giving up too quickly instead of experimenting with device gestures like tilting, shaking, or using multiple fingers.
Tips
- Brain Test rewards questioning fundamental assumptions about how puzzles work.
- Consider what information the puzzle DOESN'T give you, not just what it does.
- Remember: Brain Test Level 245 has a difficulty rating of 4/5 — it requires advanced lateral thinking.
