🧩 Level Info

• Level Number: 123
• Puzzle Statement: Shake the Phone
• Difficulty: Easy

🎯 Objective

Clear the stage by actually shaking your smartphone device without tapping or swiping the screen.

📝 Solution Steps

1. When the stage begins, confirm the instruction "Shake the Phone" written on the screen.
2. Without moving anything on the screen, hold the smartphone (or tablet) device you are playing on in your hand.
3. Shake the device up and down or left and right with enough force to be noticeable, several times.
4. When a certain level of vibration is detected, the puzzle will automatically be cleared.

💡 Hints

• No matter how much you tap the screen, nothing might change. Consider alternative ways to operate.
• This puzzle requires you to deal with "the smartphone itself" rather than within the screen.
• This is a type of problem that uses the accelerometer built into the device. Try shaking the smartphone itself.

🧠 Explanation & Points

This level is a trick question type where the puzzle statement itself is the solution. It exploits the player's preconceived notion that they must "tap something" or "there should be a draggable mechanism" and deliberately doesn't place objects on the screen for resolution, instead requiring the real-world action of shaking the device itself. It is a very simple gimmick using the accelerometer (a function that detects vibration and tilt) installed on the smartphone.

🔍 Common Mistakes

• Repeatedly tapping the screen text "Shake the Phone".
• Trying to drag the text or pinching in and out to zoom in or out.
• Thinking it can be done by simply tilting the phone, and waiting by slowly tilting without shaking.
• Repeatedly pressing the settings icon or other buttons (if any) to find a hidden button.
• Closing the app once or trying to manage with physical buttons like the home button or power button of the device.

🎉 Post-Clear Advice

This was a super simple sensor-based problem that could be cleared just by shaking the smartphone. In Brain Test, there are times when you will be required to perform real-world actions like "shaking, tilting, rotating" besides touching the screen. If you get stuck in the future, consider how you might be able to move the device itself.
