🧩 Level Information

• Level Number: 33
• Problem Statement: Shake the phone to open
• Difficulty: Easy

🎯 Objective

Shake the phone itself to open the lock (or door) on the screen.

📝 Solution Steps

1. Observe the game screen carefully and make sure there are no special buttons or keyholes.
2. If tapping or swiping the screen results in no or little response/opening, recognize it as a problem that can't be solved by usual operations.
3. Hold the smartphone (or tablet) firmly and shake it left to right or up and down, taking care not to drop it.
4. By shaking it hard enough, the game will detect the shaking motion of the device, open the lock (or door), and the stage will be cleared.

💡 Hints

• If tapping the screen doesn't open anything, think of utilizing the smartphone itself.
• This puzzle uses the 'movement of the device' instead of touch operations. It involves a mechanism using the accelerometer.
• Hold the smartphone tightly, taking care not to drop it, and try shaking it left, right, up, or down.

🧠 Explanation & Points

This level serves a tutorial-like role in which players are reminded of 'operations other than screen touch.' In the Brain Test series, it's common to incorporate real-life actions like shaking, tilting, or rotating the device into puzzles, and this stage is a typical example of that. Since there are few special clues on the screen and normal taps or drags don't change the situation, a shift in thinking to 'maybe I need to move the smartphone itself?' is required. Although the difficulty is relatively low, it might pose a trickier element for those not accustomed to problems using smartphone sensors.

🔍 Common Mistakes

• Continuously tapping on the door or lock part on the screen.
• Repeatedly trying different variations of touch operations like swiping or long-pressing.
• Trying pinch-in or pinch-out (zooming in/out) and straying further from the answer.
• Stopping after only slightly tilting the device and mistakenly thinking 'that's not it' (you actually need to shake it more firmly).

🎉 Advice After Clear

After clearing this stage, get used to the unique Brain Test idea that 'screen operations are not the only solution.' Problems utilizing real-world movements like tilting, turning upside down, or shaking the device will continue to appear. If you get stuck in the same way, develop a habit of first suspecting 'maybe it's a mechanism involving moving the smartphone itself,' and you'll be able to solve it more smoothly.
