Brain Test Level 31 Walkthrough: Let's Cross the Dangerous Bridge
Complete Walkthrough, Step-by-Step Explanation, Common Mistakes
🧩 Level Information
- Level Number: 31
- Question: The car is about to fall through the crack in the bridge! Help it cross safely.
- Difficulty: normal
🎯 Objective
Safely guide the car across the bridge without letting it fall.
📝 Steps to Solve
- Press and hold with one finger on the 'crack' part in the middle of the bridge, and do not release your finger.
- While keeping one finger holding the crack, use another finger to tap the 'car'.
- When you tap the car, it will automatically move forward and cross the bridge.
- Once the car has safely crossed the bridge, release your finger to clear the level.
💡 Hints
- Focus on the broken part (crack) of the bridge.
- Although the bridge is broken, you won't find parts to repair it by dragging or swiping.
- Consider whether there is a mechanism to 'press and hold'.
- Try pressing and holding the crack while tapping the car with another finger.
🧠 Analysis and Key Points
This stage is a puzzle designed to make players realize they need to use 'multi-touch' (touching two places simultaneously). While it looks like a stage where you need to repair a broken bridge, you actually don't need to move or combine items. Instead, it requires smartphone-specific thinking, where you press and hold the crack as support with your finger.\n\nMany players initially try to just move the car and let it fall, or attempt to repair the bridge by swiping, but these actions have no effect and lead to a dead end. Remembering both 'press and hold' and 'two-finger operation' is the key to solving this puzzle. By holding the crack, the game treats the bridge as being 'supported', allowing you to move the car safely with the other finger.
🔍 Common Mistakes
- Repeatedly tapping the car to move forward, causing it to fall off the bridge each time.
- Trying to drag the crack on the bridge or rubbing it with your finger to repair it.
- Wasting time by testing if other objects on the screen (sky, clouds, ground, etc.) can be moved.
- Though attempting to press and hold, only using one finger and misinterpreting the lack of response due to not controlling the car simultaneously.
- Forgetting the 'two-finger operation (multi-touch)' unique to smartphone games, continuing to think with the assumption of only touching one point.
🎉 Advice After Clearing
This stage reveals the unique smartphone mechanism of supporting the crack with your finger. In future levels, mechanisms involving 'press and hold' or 'simultaneous tap/drag with two fingers' will increase, so always consider operations other than tapping to solve puzzles more easily.
