🧩 Level Information

• Level Number:472
• Problem Statement:Insert the engine that opens both bonnets into the car on the left
• Difficulty:normal

🎯 Objective

Find the “correct engine” that can open both bonnets and set it into the car on the left side.

📝 Solution Steps

1. First, observe the screen and identify the two cars lined up on the left and right, and the multiple engines (icons) lined up at the bottom.
2. Check carefully the marks, arrows, and displays to see which engine might have the ability to 'open both bonnets' (hints include arrows pointing both left and right or icons indicating both cars).
3. Ignore engines that seem to indicate only one side (with single-sided arrows or marks) and look for engines that indicate both sides.
4. Press and hold the engine with marks indicating both directions, and drag and drop it onto the bonnet section of the car on the left.
5. When the correct engine is inserted into the left car, both bonnets will automatically open, and the level will be cleared.

💡 Hints

• First, focus on parts other than cars, especially pay attention to the design differences of the engines at the bottom of the screen.
• Don’t the engines have marks that look like 'left only', 'right only', or 'both sides'?
• Marks indicating only one side will not meet the conditions. Look for icons that meet the condition of 'opening both bonnets'.
• Try dragging the engine with signs indicating both directions to the bonnet of the car on the left side.

🧠 Analysis & Points

The problem statement is 'Insert the engine that opens both bonnets into the car on the left', and at first glance, it seems like simply inserting the engine into the car on the left. However, the essence is to 'figure out which engine can open both bonnets'. Players often imagine a 'symmetrical combination' such as a left-specific engine for the left car and a right-specific engine for the right car. However, in reality, there is one engine prepared that corresponds to both sides, and when it is inserted into the left car, both bonnets open, which is a slightly twisted arrangement. This level demands a keen observation of icons and marks, as well as a shift in thinking that 'there is a common part that works for both'. It’s a simple yet easy-to-overlook type of trick.

🔍 Common Mistakes

• Trying to insert separate engines into each of the left and right cars, dragging left-only and right-only engines sequentially.
• Initially tapping the bonnet directly to open it, leading to confusion when nothing happens.
• Inserting the most left (or right) engine into the left car without closely examining the design or marks on the engines.
• Focusing only on the 'insert engine into the car on the left' part without reading 'open both bonnets', failing to select the correct engine.

🎉 Advice After Clearing

If you can identify the 'common engine' that opens both bonnets and insert it into the left car, the stage is cleared. The key point of this stage is to combine text conditions and icon information. In subsequent levels, subtle differences in appearance or wording in descriptions often hold the key to answers, so pay attention and observe closely.
