Brain Test 5 Level 52

Overview

This level is a mosquito-swatting puzzle spread across three notebook pages. The opening page reads "Get rid of the actual mosquito." and shows a single mosquito hovering near the ground while a girl stands off to the side on the grass. Later pages introduce more mosquitoes and two long wooden planks covered in screws, which act as a giant flyswatter when brought together. The overall approach is to use the two planks like a clamp: slide them toward each other so they close on every mosquito on the page, squashing all of them at once.

• Difficulty: Easy
• Estimated moves: 4

Step-by-Step Solution

1. On the first page, locate the single mosquito hovering above the grass line. Tapping it directly will not work — it will just fly away or reappear. Look for the two wooden planks that appear in later rounds: one horizontal plank near the top of the page and one near the bottom.
2. Drag the top plank downward and the bottom plank upward so they move toward each other. Think of them as the two halves of a giant flyswatter. Any mosquito caught between the two planks gets squashed when they close together.
3. On the second round, more mosquitoes appear scattered at different heights. Adjust the gap between the two planks so they cover the full vertical range where the mosquitoes are flying. You may need to move both planks several times to catch every mosquito in one clamp.
4. In the final round, a padlock appears near the center where the planks cross. Ignore the lock — it does not stop the planks from closing. Keep bringing the planks together until all mosquitoes are squashed.
5. When every mosquito on the page has been eliminated, a large green checkmark appears in the center of the page between the planks, confirming the level is complete.

Strategy & Reasoning

The puzzle works because tapping individual mosquitoes is ineffective — they keep respawning or moving away. The only reliable way to eliminate all of them at once is to use the planks as a large-scale swatter. The screws on the planks are just visual detail; they do not add any functional constraint.
The reason this approach is optimal is that the mosquitoes are spread across different vertical positions. If you only move one plank, you might catch the top mosquitoes but miss the bottom ones, or vice versa. Moving both planks to meet in the middle creates a clamp zone that covers the whole page. Alternatives like trying to swat the girl or moving her out of the way do nothing — she is not part of the problem.

Tips & Common Mistakes

• Do not waste time tapping individual mosquitoes; they will not die from a tap and will just reappear. The planks are the only tool that works.
• Do not move the planks all the way off the page; you need them to close together, not disappear. Stop when the gap between them is small enough to trap every mosquito.
• Do not worry about the padlock on the planks; it is decorative and does not prevent the planks from moving or closing.
