🧩 Level Information

• Level Number: 174
• Question: Rub away the "1" from 19
• Difficulty: Easy to Medium

🎯 Objective

Rub away only the "1" from the number "19" displayed on the screen using your finger.

📝 Steps to Solve

1. Identify the number "19" displayed in the center of the screen (or near the problem statement).
2. Place your finger on the left digit "1" of the "19".
3. Without lifting your finger, rub left and right or in circular motions as if using an eraser.
4. Continue rubbing for a while, and the "1" will gradually fade away and eventually disappear.
5. When the "1" is completely gone and only "9" remains, the stage is cleared.

💡 Hints

• Try not only tapping, but also swiping or "rubbing" motions.
• The problem statement says 'rub away', so taking it literally is key.
• There is no need to look for other items or buttons; directly rub the number '19'.
• Moving in a consistent rubbing motion rather than short swipes makes it easier to erase.

🧠 Explanation・Points

This level is a tutorial-like puzzle that requires the somewhat special operation of rubbing with a finger. The problem statement 'rub away the "1" from 19' almost fully indicates the solution, so noticing this literal action becomes the point. Many players tend to first try basic actions like tapping or long-pressing, but in this game, the smartphone-specific operations such as "rubbing", "shaking", and "zooming in/out" are frequently used. Here, as one example, the portion of "1" is continuously traced with a finger, making the number disappear as if erased with an eraser. No extra calculation or new ideas are necessary; trusting the text straightforwardly leads to the correct action in this stage.

🔍 Common Mistakes

• Tap the '19' just once believing it will clear, and end up tapping multiple times.
• Attempt to erase by long-pressing the '1', ending up wasting time with no effect.
• Misinterpret 'rub away' as a metaphor, and search for other items or buttons like an eraser across the screen.
• Try rubbing the '1' in the problem statement instead of the '19', leading to confusion when nothing happens.
• Randomly swipe across the screen without properly rubbing the '1's position, mistakenly thinking it doesn't disappear.

🎉 Advice After Clearing

Once the "1" is completely erased and only "9" remains, the stage is cleared, and you'll progress to the next level having learned how to use the rubbing motion type of trick.
