🧩 Level Information

• Level Number: 89
• Question: Turn your smartphone upside down and shake it up and down
• Difficulty: Normal

🎯 Objective

Clear the stage by turning your smartphone upside down and shaking it up and down.

📝 Solution Steps

1. Firmly hold the smartphone (device) with one hand or both hands.
2. Rotate the smartphone body 180 degrees so that the screen becomes upside down.
3. In this upside-down orientation, lightly shake the smartphone up and down.
4. Once a reaction (clear animation) occurs on the screen, return the smartphone to its original orientation.

💡 Hints

• Tapping or swiping on the screen might not do anything. Focus on the orientation of the device itself.
• The word 'upside down' is a hint. Try rotating the smartphone screen until it becomes upside down.
• It's not enough just to change the orientation. After turning it upside down, try shaking the smartphone up and down.
• This is a problem that uses motion sensors (gyro/accelerometer). You don't need to shake it too hard, so be careful not to drop it and shake it lightly.

🧠 Analysis & Points

This level is a 'device gimmick' puzzle that utilizes the orientation and motion of the smartphone body rather than screen operations. The instructions 'turn your smartphone upside down' and 'shake your smartphone up and down' are direct hints for the solution, emphasizing the importance of how literally you can take the text. Many players first try things that can be done on the screen (tap, swipe, drag, etc.), but since no response occurs, they tend to get stuck. The key is whether you can switch your mindset to 'perhaps I should move the device.' Technically, it is assumed that this puzzle uses the smartphone's accelerometer and gyroscope to detect the device's upside-down orientation and vertical shaking. This kind of level also serves as a tutorial to teach that the game doesn't end with just touch operations, suggesting that similar gimmicks (tilting, shaking, rotating, etc.) will appear in the future. Carefully read the instructions and broaden your perspective beyond the screen to include real-world operations.

🔍 Common Mistakes

• Repeatedly tapping or long-pressing the screen, waiting for something to happen on the screen.
• Trying to move objects on the screen with swipe or pinch operations.
• Shaking it up and down without turning the smartphone upside down first and giving up because of no response.
• Being satisfied with just turning it upside down and not performing the shaking motion.
• Shaking it too hard, risking dropping the smartphone or actually dropping it.

🎉 Advice After Clearing

Once cleared, you will experience that there are types of gimmicks that utilize the orientation and vibration of the device. In subsequent levels, when nothing happens, remember the perspective of 'how can I move the smartphone body' to get unstuck. This stage helps you develop the habit of considering real-world operations as part of the puzzle, not just relying on touch.
