Brain Test Level 67 Walkthrough: Turn 100 into 1
Complete Walkthrough, Step-by-step Guide, Common Mistakes
🧩 Level Info
- Level Number: 67
- Question: Swipe the 00 in 100 to move it and press the button to make it 1
- Difficulty: Normal
🎯 Objective
Swipe away the '00' in "100" displayed on the screen with your finger, change it to "1", and then press the button to clear the level.
📝 Steps to Solve
- Carefully observe the number "100" on the screen, paying special attention to the '00' part on the right of the '1'.
- Long press the '00' with a single finger, and then swipe to drag it either to the left or right.
- Slide the '00' all the way off the edge of the screen to move it to an invisible area.
- Make sure only "1" is displayed after the '00' has disappeared.
- Tap the button labeled "Make it 1" or a nearby button.
- Pressing the button will clear the stage.
💡 Hints
- Pressing the button repeatedly will not turn it into 100. Consider whether you can manipulate the text itself on the screen.
- The "100" part is not just for decoration; you might be able to move it with your finger, especially by swiping the '00'.
- If you move the '00' elsewhere, "100" changes to "1". Press the button in that state to clear the level.
🧠 Explanation & Points
This level requires the player to adopt the unique Brain Test idea of 'being able to move the displayed text or numbers'. The question "Swipe the 00 in 100 to move it and press the button to make it 1" is structured to already hint at the solution. Rather than thinking of a logical way to reduce 100 to 1, the trick is to physically remove the '00' in "100" to leave only the '1'. The key is to focus not on the numerical value but on the appearance (format), which helps train the thought process for other Brain Test levels involving 'dragging text or numbers to rewrite sentences'.
🔍 Common Mistakes
- Repeatedly pressing the button, attempting to press it 100 times.
- Tapping only other objects (buttons or backgrounds) on the screen, not realizing the text "100" itself can be moved.
- Double-tapping or long-pressing on the 00 area, looking for a gimmick that reduces the count for "Make it 1".
- Attempting to drag the entire "100" unsuccessfully, then giving up (the correct approach is to swipe only the '00' part).
🎉 Advice After Clearing
Once you get accustomed to the classic Brain Test trick of 'dragging text or numbers', you'll have more aha moments in future levels. In the next stage, always be suspicious of whether you can move the visible numbers or words themselves.
