🧠 Explanation & Points
This level is more about testing your ability to "read the text plainly" than your calculation skills or logical reasoning. Many players mistakenly interpret it as 'big number = as large as possible' or 'think of the maximum value', leading them to enter large numbers like 9999 or 1000. However, the text already specifies a particular number '999'. In essence, the whole sentence 'Enter 999 because it's a big number' is a directive, and the answer lies within the text. It's important to take the directive at face value and interpret it straightforwardly. This is a representative pattern of text-based puzzles and instruction puzzles.
🔍 Common Mistakes
- Focusing solely on the words 'big number' and entering another large number like 9999, 1000, or 1000000.
- Misunderstanding it as a maximum value problem and thinking that increasing the digit count will yield the correct answer.
- Not reading the text to the end and prematurely entering based on the initial phrase 'because it's a big number...'.
- Trying to think of a clever large number, such as a negative or decimal number with a large absolute value.
🎉 Post-Clear Advice
Getting accustomed to problems where 'the answer is written within the text' will help reduce premature actions in future levels. Instructions such as "enter ~" or "press ~" often constitute the correct answer, and it is advisable to develop a habit of carefully reading the instructions from start to finish.
