Brain Out Level 79

Overview

The prompt "Please enter a 5-digit number password" shows a pink hand mirror on the left and pink text reading Err0r on the right. The mirror is a hint: the answer is hidden in the reflection. The text Err0r, when viewed as mirrored digits, spells out a five-digit number.

• Difficulty: Hard
• Estimated moves: 2

Step-by-Step Solution

1. Look at the pink text Err0r on the right. Notice that the 0 is a zero, not the letter O.
2. Place the hand mirror next to the text, or mentally reflect the text horizontally. The mirrored letters look like digits:

• E reflected looks like 3.
• r reflected looks like 7.
• The next r also looks like 7.
• The 0 stays 0.
• The last r looks like 7.

1. Read the reflected digits in order: 7 0 7 7 3.
2. Tap the input field and type 70773.
3. Tap OK. The congratulations popup appears with the message "Cooooool!"

A pink mirror sits next to the text Err0r. The mirror is the clue: the answer is hidden in the reflection. E reflected looks like 3, and r reflected looks like 7.

Mirror the text horizontally: E becomes 7, r becomes 7, r becomes 7, 0 stays 0, r becomes 7. Read the reflected digits: 70773. Type 70773 and tap OK.

Type 70773 into the input. The mirrored text Err0r reads as digits: 7, 0, 7, 7, 3. If you type any other number, the level rejects it.

Type 70773. If you type any other number, the level rejects it. The mirror reflection is the only way to read the password.

Strategy & Reasoning

The mirror is the key. In a horizontal reflection, the capital E flips to resemble a 3, and the lowercase r flips to resemble a 7. The 0 is already a digit. Reading the mirrored text left to right gives 70773, which is exactly five digits as the prompt requires. The word "Error" was deliberately written with a zero (Err0r) so that the reflection produces a valid number.

The mirror reflection is the key. Each letter, when mirrored horizontally, resembles a digit: E looks like 3, and r looks like 7. The 0 is already a digit. Reading the mirrored text left to right gives 70773, which is five digits. The word Error was deliberately written with a zero so that the reflection produces a valid number.

The mirror is held up to the text conceptually. You do not actually need to drag the mirror; the letters themselves, when viewed mirrored, form the number 70773. Type that number to clear the level.

Tips & Common Mistakes

• Do not type Error or ERR0R. The input expects a five-digit number, not letters.
• Do not read the text as-is. You must mentally mirror it, with E becoming 3 and r becoming 7.
• Do not forget the middle zero. It is a digit and must be included.
