Brain Test Level 15 Solution: Tap in the order of 1,49,80,5,7,11,101
Complete Solution · Step-by-Step Guide · Common Mistakes
🧩 Level Information
- Level Number: 15
- Problem Statement: Tap in the order of 1, 49, 80, 5, 7, 11, 101
- Difficulty: Easy
🎯 Objective
Correctly tap the number buttons on the screen in the order of “1 → 49 → 80 → 5 → 7 → 11 → 101”.
📝 Steps to Solve
- Find all the numbers (1 / 49 / 80 / 5 / 7 / 11 / 101) displayed on the screen. They are scattered all over the place, so look at the entire screen to avoid missing any.
- Tap “1” first. Be careful not to confuse it with similar-shaped numbers (e.g., 7).
- Next, tap “49”. Look for “49” among the two-digit numbers and tap precisely.
- Then, tap “80”. It's easy to spot numbers with a zero, but be cautious of tap mistakes.
- Tap “5” next. When numbers are clustered, carefully aim for “5” to avoid mistakes.
- Next, tap “7”. Make sure to tap the active “7” without confusing with already tapped numbers.
- Then, tap “11”. Confirm the number of digits carefully before tapping to avoid confusing it with “1”.
- Finally, tap “101”. This should be the only three-digit number, so tap calmly and accurately.
- If you can tap all in the correct order, you clear the stage. If you make a mistake, you must restart and tap again in the correct order from the beginning.
💡 Hints
- The number order written in the problem statement is exactly the order for tapping. There is no need to think about unnecessary calculations or patterns.
- Instead of pressing the numbers on the screen in order of size (1,5,7,11,49,80,101), you must always tap according to the instruction “1,49,80,5,7,11,101”.
- If you tap even one wrong number, it will be considered a fail. To reduce mistakes, verbally confirm the next number to tap every time.
- Numbers like “1”, “11”, “101” look similar and are easy to mistakenly tap. By being aware of the number of digits (1-digit, 2-digit, 3-digit), it's easier to distinguish.
🧠 Explanation & Tips
This level is not a puzzle that tests calculation or insight tricks; it tests whether you can precisely follow instructions as they are. Many players, when they see numbers lined up, naturally try to find patterns like “smallest to largest”, “largest to smallest”, or “regular sequence”. However, this problem does not require such patterns and only needs you to trace the order written in the instructions. In Brain Test, there are often problems designed to make you imagine complicated rules, but in reality, they can be solved just by reading carefully. This level is one of those, requiring attention and care. Especially, with similar numbers like “1”, “11”, “101”, which are easy to mix up, it's good to develop the habit of checking the number of digits and arrangement before tapping, which will be helpful in future levels.
🔍 Common Mistakes
- Tapping numbers in order of size (1→5→7→11→49→80→101) instead of following the problem statement. A typical mistake when the problem statement is not read carefully.
- Remembering the order in the problem statement incorrectly and swapping the sequence midway, such as tapping “1→49→5→80…”.
- Confusing “1” and “11”, or “101”, and tapping the wrong number. This especially occurs on small screens.
- Getting impatient and tapping rapidly, accidentally tapping a different number near the correct one.
- Trying to find hidden patterns (like arithmetic sequences or rules) in the problem statement, and not noticing the simple intention of just following the written order.
🎉 Advice After Clearing
If you tap in the order “1 → 49 → 80 → 5 → 7 → 11 → 101” as instructed, you clear the level. Developing the habit of reading instructions carefully helps in tackling tricky problems that will come afterwards. The next level awaits you with challenges testing your intuition and creativity.
