🎯 Objective
Find the "half" of the displayed number and enter "5" as the answer.
📝 Steps to Solve

- Enter the number "5".
- After confirming the "5" you entered, tap the OK button (checkmark or submit button) to confirm.

💡 Hints
- Focus on the Japanese expression "half of the number" in the puzzle text and consider if any special operation is needed.
- Instead of counting the whole visible number, can't it refer to "half of a particular number"?
- In many cases, "half of 10" is 5. The puzzle's intention is also based on the idea that "half = 5".
- Without overthinking, simply enter "5" in the answer field and try to confirm.
🧠 Explanation & Points
This stage is a simple trick question testing whether you can straightforwardly arrive at the answer from the word "half" rather than the calculation itself. In Brain Test, there are often puzzles where you're told to "halve" the apples or objects displayed, requiring you to actually remove or move half, but unlike those, this level does not require special drag operations or hidden mechanics. It's a problem built to utilize the commonly associated relationship "half of 10 is 5" from the phrase "half of a number". When players try to split objects on the screen or start complex calculations, they tend to fall into a trap. The correct answer, which is simply entering "5", serves as a reminder not to overthink things.
🔍 Common Mistakes
- Counting objects (like apples or other icons) drawn on the screen and trying to divide that by 2.
- From the word "half", attempting to drag objects to split them into two.
- Thinking of "half" as a fraction and trying to enter 1/2 or 0.5.
- Frantically tapping the screen trying to find a specific number displayed.
- Misunderstanding that there is a complex calculation or operation, trying various numbers (2, 3, 4, etc.) in a trial and error manner.
🎉 Post-Clear Advice
If you straightforwardly interpret "half of a number = 5", you can clear this stage instantly. The next level may require more twisted language expressions or a change in perspective, so keep your mind flexible as you proceed.
