🧩 Level Info

• Level Number: 304
• Question: Tap to stop the ball on the red spot and tap to stop the ball on the blue spot
• Difficulty: Hard

🎯 Objective

Stop one ball in both the red and blue areas simultaneously. Make it appear as if one ball satisfies two conditions at the same time.

📝 Steps to Solve

1. First, observe the ball and confirm the position relationship of the red and blue areas. The ball is moving automatically, but will stop when tapped.
2. You will notice that if you try to stop it on 'red' and 'blue' areas separately, fulfilling one condition will prevent you from fulfilling the other. This indicates that it cannot be cleared by the correct method of solving.
3. Carefully observe the red and blue areas on the screen and try to drag them if possible. Long press the colored area and slide it with your finger.
4. Once you confirm that the blue or red area can be dragged, adjust their positions so the two colored areas overlap. That is, stack the red and blue areas in the same place.
5. After cleanly overlapping the red and blue areas, wait for the ball to pass through the overlap point. Tap the screen the moment the ball comes right over the overlap area to stop the ball.
6. The ball stops 'on top of the overlapped area of red and blue', which apparently allows you to clear the level by achieving the conditions of "stopping on the red spot" and "stopping on the blue spot" at the same time.

💡 Hints

• First, try to stop it with both red and blue honestly. It's important to confirm whether or not it can really be done like that.
• If you feel that 'it satisfies only one side no matter what', then question whether only the ball can be moved. Try long pressing & dragging other objects on the screen.
• Try to see if the colored parts (red or blue areas) can be moved? Or can they be overlapped? Trying this will open the path forward.
• Once you overlay the red and blue areas in the same spot, you can clear both conditions just by stopping the ball once.

🧠 Analysis & Key Points

This stage is a kind of trick question that requires achieving 'two conflicting instructions with one action'. Players tend to interpret the instruction literally: 'stop the ball at the red spot → then stop at the blue spot', but repeating this won't simultaneously satisfy the conditions. Here, it's necessary to shift your approach to 'is it really only the ball that can be moved?'. In Brain Test, even objects that look like part of the background are often movable. In this problem, by moving the red and blue areas themselves and overlapping the two colors, the puzzle expects you to meta-solve it by making it possible to satisfy the two conditions simultaneously with one ball stop. Logically, it is a puzzle where 'manipulating the conditions resolves the contradiction', and in the context of the game, it serves as a practice problem for breaking fixed ideas.

🔍 Common Mistakes

• After stopping the ball on red, trying to move it again to stop it on blue next. This does not satisfy the conditions 'simultaneously', thus the stage will not clear.
• Trying to solve the problem only with the speed or timing of the ball, endlessly changing the tap timing. Fundamentally, it is a different type of problem.
• Trying to move the ball itself to any position by long-pressing and dragging. This is a common thought in many levels, but the solution for this stage is to 'move the colored areas'.
• Mistaking the red or blue areas as 'buttons' and thinking that something will happen just by tapping and not trying to drag, leading to being stuck.

🎉 Advice After Clearing

If you noticed the idea of moving and overlapping the red and blue areas, it's proof that you are getting quite familiar with the 'trick of manipulating the conditions themselves' specific to Brain Test. In future levels, moving seemingly fixed objects such as backgrounds, labels, and colored areas may lead to new solutions.
