Brain Test Level 9 Walkthrough: Match the Yellow Ball with the Blue Ball
Complete Walkthrough, Steps Explanation, Common Mistakes
🧩 Level Information
- Level Number: 9
- Task: Match the Yellow Ball with the Blue Ball
- Difficulty: Easy
🎯 Objective
Drag and move the yellow ball on the screen to overlap and match with the blue ball.
📝 Steps to Solve
- Check the positions of the yellow and blue balls on the screen.
- Confirm that you can drag the yellow ball by long-pressing it with your finger.
- Slowly slide the yellow ball and move it towards the blue ball.
- Drag and match until the yellow and blue balls perfectly overlap (touch each other).
- The level will be cleared when the two balls overlap.
💡 Hints
- First, try to see which objects can be moved. You can find out by long-pressing or dragging.
- If nothing happens by just tapping, moving objects is the baseline of this game.
- Leave the blue ball as is and try moving the yellow ball. The goal is to stick them together.
- Try bringing the balls completely close to each other. If they are slightly apart, it might not clear.
🧠 Analysis & Points
This level is a simple problem that makes players learn the basic operation of Brain Test, 'drag to move.' Once you realize the idea of directly moving objects with your finger, you can quickly solve it, but if you try to solve only by tapping, you won't make progress. You should just move the yellow ball and hit it with the blue ball, with no specific order or hidden gimmicks. Touching objects and 'first trying them' is an important concept common to this type of puzzle.
🔍 Common Mistakes
- Just tapping the yellow or blue balls multiple times without trying to drag them.
- Trying to move the blue ball unsuccessfully and not noticing the easily movable yellow ball.
- Not bringing the balls close enough and stopping at a slightly distant position, resulting in no clear judgment.
- Overthinking that there might be some hidden button, overlooking the simple idea of aligning the balls.
🎉 Advice After Clearing
By successfully overlapping the yellow ball with the blue ball, the level clear animation plays, and you will get a sense of getting used to drag operations. Along with the sense of 'Ah, it was movable after all,' you'll feel encouraged to touch objects actively in the future as well.
