Brain Test Level 424 Walkthrough: Move the Star Behind the Curtain to the Tree
Complete Walkthrough・Step-by-Step Guide・Common Mistakes
🧩 Level Info
- Level Number:424
- Question:Open the curtain and swipe the star to the tree
- Difficulty:Easy-Medium
🎯 Objective
Open the curtain and drag the revealed star to the top of the Christmas tree and set it.
📝 Step-by-Step Solution
- First, check the fabric part of the 'curtain' on either or both sides of the screen.
- Tap the edge of the curtain with your finger and swipe sideways (outwards) to open the curtain. Opening one or both sides will reveal a 'star' behind it.
- Press and hold the 'star' icon visible behind the curtain to grab it.
- Without releasing your finger, drag (swipe) the star to the top of the 'Christmas tree' near the center of the screen.
- Place the star securely on the top branch of the tree to automatically clear the level.
💡 Hints
- First, try touching the 'curtain' itself. The fabric might open to the sides.
- Instead of tapping on areas where nothing happens, try swiping on 'movable objects (curtains)'.
- The star is not visible initially. Look behind the curtain.
- After finding the star, simply tapping is not enough. Drag and place it to the 'top of the tree'.
🧠 Analysis and Key Points
This stage is a straightforward puzzle where the 'instructions themselves are the answer,' with few special tricks. However, since the star is not visible initially, it requires the idea of 'opening' the curtain—an action one would do in the real world. Many players tend to tap the screen frequently, looking for stars or trees visible from the start, but this game often uses the convention of 'revealing hidden objects by swiping.' This level is designed to affirm that convention. The operation itself requires just two steps: sliding the curtain sideways to open it → dragging the star to the top of the tree. Once you have the idea, you can solve it quickly.
🔍 Common Mistakes
- Attempting to open the curtain by just tapping and not swiping, resulting in no action.
- Randomly tapping or holding the screen, mistakenly thinking the star is nowhere to be found.
- Fiddling with just the area around the tree and trying to swipe the tree without any result.
- Even after finding the star, thinking it will clear by simply tapping, forgetting to drag it to the top of the tree.
- Placing the star in the middle of the tree or elsewhere, resulting in misjudgment (the star needs to be placed on top of the tree).
🎉 Post-Clear Advice
After placing the star on the top of the tree, a completed Christmas tree will be displayed. Savor the satisfaction of finding and decorating the hidden star, and move on to the next level.
