🧩 Level Information

• Level Number: 311
• Puzzle: Tap the device marks in the order of the line colors on the right wall.
• Difficulty: normal

🎯 Objective

Check the colors of the lines (cables) on the right wall from the top in order: "Blue → Red → Yellow → Green", and tap the device marks (buttons) in that order to correctly activate the device.

📝 Steps to Solve

1. Focus on the right side of the screen and check the color of the vertically aligned lines (cables) from the top.
2. Remember that the colors of the lines from the top are "Blue, Red, Yellow, Green". If necessary, repeat the order in your mind several times.
3. Find the device panel (part where multiple marks/buttons are lined up) in the center or bottom of the screen.
4. Find the mark (or button) corresponding to "Blue" among the device marks and tap it once.
5. Next, tap the mark corresponding to "Red" once.
6. Then, tap the mark corresponding to "Yellow" once.
7. Finally, tap the mark corresponding to "Green" once.
8. Once you have correctly tapped in the order "Blue → Red → Yellow → Green", the device will operate and the stage will be clear.

💡 Hints

• First, observe the right wall carefully and look for anything that could be a hint.
• There should be several vertically aligned lines (cables) on the right wall. Check the order of their colors.
• Once you know the order of the colors, simply tap the device marks (buttons) in that order.
• The color order is "Blue → Red → Yellow → Green" from top. Tap accordingly.

🧠 Analysis & Points

This stage is a memory and observation puzzle that uses the color of the lines (cables) on the right side of the screen as the "input code". The lines are arranged from top as Blue, Red, Yellow, Green, and that arrangement indicates the operation order of the device. Players should first observe whether there are any hidden hints in the background, and then simply remember the color order and press the corresponding buttons, so the mechanism itself is simple. However, if you don’t realize that the line colors correspond one-to-one with the device marks, you might press the buttons blindly and have to restart several times. It's a level that tests the common Brain Test concept of "background decoration = hint".

🔍 Common Mistakes

• Randomly tapping the device buttons without noticing the color order.
• Looking for hints elsewhere (floor, ceiling, characters, etc.) without carefully observing the right wall.
• Mistakenly remembering the color order as something similar but incorrect, like 'Blue → Yellow → Red → Green'.
• Pressing the same color button repeatedly or skipping the order midway.

🎉 Advice After Clearing

If you noticed that the line colors became the input order for the device, your observation skills are spot on. In future stages, small details in the background colors and arrangements often hold the key to the answers, so make sure to observe carefully before taking action.
