🧩 Level Information

• Level Number: 66
• Question: No squares, so submit 0
• Difficulty: easy

🎯 Objective

Notice that there is not a single square on the screen, and enter "0" to submit.

📝 Solution Steps

1. Look at the entire screen and check whether there are any squares among the shapes and buttons.
2. Upon close inspection, you can see that there are only circles, triangles, and other shapes displayed, with no squares present.
3. According to the problem statement "No squares, so submit 0," decide that since there really are no squares, the answer should be 0.
4. Tap on the input field and enter "0".
5. After entering, tap the "Submit" button (or the Confirm button).
6. You succeed and clear the stage.

💡 Hint

• First, check each shape on the screen to see if there really are any squares.
• Even if something looks like a square, upon closer examination, it might be slightly different in shape or just a decoration.
• Read the problem statement plainly. Focus on the part that says "No squares."
• If you really can't find any squares, consider what that number might be.
• Try entering "0" in the input field and submit.

🧠 Analysis & Key Points

This stage utilizes the player's "suspicious nature" against them. In many Brain Test stages, the problem statement is made intentionally confusing, causing players to overthink and wonder if there is a hidden square somewhere. However, in this level, the problem statement itself is the answer, and the correct solution is to take the sentence "No squares, so submit 0" at face value. Confirm that there are no squares by thoroughly checking the screen, and proceed from there to arrive at the answer "0".

🔍 Common Mistakes

• Counting buttons, frames, or menus as "squares" on the screen and entering a number greater than 0.
• Forcing shapes to be squares and entering an arbitrary number like 3 or 4.
• Thinking the problem statement is a trick and overthinking that there is actually another solution.
• Not trying 0 and wasting time entering various numbers without a clear guess.

🎉 Advice After Clearing

In this level, it was important to trust the problem statement as it was. In Brain Test, there are times when overthinking is necessary, and times like this when straightforwardness is required. In the next level, make sure to observe both the entire screen and the text carefully before making a judgment.
