Brain Test Level 45 Walkthrough: Accelerate the Blue Car with Hidden Nitro
Complete Guide, Step-by-step Explanation, Common Mistakes
🧩 Level Information
- Level Number: 45
- Problem Statement: Use the hidden nitro in the top right for the blue car and press Go!
- Difficulty: Normal
🎯 Objective
Find the nitro booster hidden in the top right of the screen, use it on the blue car, and then press the "Go!" button to win the race.
📝 Steps to Solve
- Carefully examine the area around the top right of the screen and swipe with your finger to find any hidden items.
- Press and hold the nitro can (booster) that appears from the top right and grab it.
- Drag the nitro can and drop it onto the blue car to equip it.
- Once the nitro is set on the blue car, tap the "Go!" button on the screen.
- The blue car, accelerated by nitro, will start running, and the stage will be cleared.
💡 Hints
- Not everything visible on the screen is all there is. There's a "hidden item" somewhere.
- Especially suspect the "edges" of the screen. Try swiping around the top right.
- The item you find is nitro (booster). Pay attention to the color when deciding which car to use it on.
- After placing the nitro on the correct car, pressing the "Go!" button will lead to clearing the stage.
🧠 Analysis & Points
This stage uses a classic Brain Test trick of finding objects hidden around the outside or edges of the screen. Players tend to simply press the "Go!" button initially, but that alone won't make the blue car fast enough to satisfy clearing conditions. Swiping the top right of the screen reveals the hidden nitro can. By dragging this nitro onto the blue car, it achieves much greater acceleration, allowing you to win the race when you press "Go!" again. The point is to not trust only the visible UI and to learn the concept common to the entire Brain Test of swiping the screen edges to find hidden elements.
🔍 Common Mistakes
- Repeating pressing the "Go!" button without doing anything else, causing the blue car to keep losing.
- Failing to notice the nitro hidden in the top right and just tapping obstacles or cars on the course excessively.
- Thinking that just tapping the top right is enough and not trying the swipe to bring out the nitro.
- Dragging the found nitro to cars other than the blue one and not seeing the desired result, causing confusion.
- Forgetting to press the "Go!" button after equipping the nitro, misinterpreting nothing happening.
🎉 Advice After Clearing
This level provides an opportunity to learn that important items can be hidden at the edges or outside of the screen. Getting into the habit of questioning unseen parts will be useful in stages with similar tricks.
