Brain Out Level 107

Overview

The prompt asks you to enter the biggest one. Scattered numbers on the board include 8, 3, 2, 9, 7, and two zeros, with an Enter field and an OK button below. A straightforward comparison would pick the digit 9 as the largest single number, but the level treats the two zeros as a pair: placing them side by side forms the infinity symbol, which represents a value larger than any finite number. The intended answer is infinity, built from the two zero buttons.

Step-by-Step Solution

1. Read "Enter the biggest one" and look at the available digits. The nonzero numbers are all single digits, and even combining them into a large integer would not be the answer the level expects. Compare the ordinary choices first: 9 is the largest single digit among the nonzero buttons, but the puzzle asks for the biggest possible value rather than the biggest visible numeral.
2. Notice the two zero digits placed lower on the board. Two zeros next to each other can be read as the infinity sign, a sideways figure eight with no upper limit. Infinity represents a quantity that never stops growing, so it outranks any finite number that can be typed.
3. Tap the first zero to place it in the entry field. Watch the field to confirm the zero registers before selecting the second one.
4. Tap the second zero right after it so the entry shows the two zeros together, forming the infinity symbol. The pair must sit side by side in the field, with no other digit between them.
5. Confirm that the two zeros are adjacent in the field and read as infinity rather than as the ordinary number zero. A lone zero would not carry the infinity meaning, so the pair is what makes the entry special.
6. Press the OK button. The level recognizes infinity as the biggest possible value and the success panel appears. If the entry is rejected, check that both zeros were selected and appear together in the field.

Strategy & Reasoning

The puzzle hinges on reinterpreting a digit as a symbol. Among finite numbers, 9 wins the comparison, but the infinity concept exceeds every finite integer, which makes it the "biggest" answer in the level's trick logic. The two zeros are supplied specifically because they can be arranged into the infinity sign; a single zero would not form that shape.

Typing the largest combination of the other digits fails because the question invites a conceptual answer rather than an arithmetic one. The board labels the entry as the biggest "one," hinting that a single symbolic value is acceptable. Once you connect two zeros to the infinity symbol, the choice is clear: any finite number, however large, is smaller than infinity. Pressing OK after the pair zeros completes the entry.

Tips & Common Mistakes

• Do not pick the digit 9 as the biggest number; the infinity symbol built from the two zeros outranks every finite digit.
• Tap both zeros so they appear side by side in the entry field; one zero alone does not form the infinity sign.
• Press OK after the two zeros are entered; rearranging the nonzero digits into a large integer will be rejected.
