Brain Out 2 Level 113
📝 Walkthrough
Overview
Level 113 instructs "Combine the largest numbers." Scattered across the screen are several symbols: an "8" next to a small circle "o", the numbers 521, 888, -1111, 99, a "2", and another loose circle "o". The victory line, "Positive infinity is the largest!", reveals that combining the 8 with a circle forms the infinity symbol.
- Difficulty: Regular
- Estimated moves: 1
Step-by-Step Solution
- Look at the options. Among 521, 888, 99, 2, and -1111, the biggest ordinary number looks like 888 or 521.
- Notice the "8" and the circle "o". Near the top-left, an 8 sits beside a small circle/letter o.
- Combine the 8 and the o. Drag the circle "o" onto / next to the 8.
- They form the infinity symbol. Merging an 8 on its side with a circle makes ∞, the infinity sign, surrounded by sparkles.
- Confirm. Infinity is larger than any finite number, so this is the largest possible combination. The screen says "Positive infinity is the largest!" and the level is cleared.
Strategy & Reasoning
This is a visual wordplay puzzle. "Combine the largest numbers" sounds like a math comparison task, and the obvious candidates are the printed big numbers like 888 or 521. But those are all finite and lose to infinity.
The trick is that the "8" and the loose circle "o" can be visually joined into the ∞ symbol. Laid on its side, an 8 fused with a loop is exactly the infinity sign. Since infinity is by definition larger than any concrete number, combining them produces the "largest" result the riddle wants.
The negative number -1111 and the small 2 and 99 are irrelevant distractors. The insight is treating the scattered shapes as a glyph to assemble rather than digits to add or compare.
Tips & Common Mistakes
- Mistake: picking 888. It is the biggest printed number, but it is still finite and smaller than infinity.
- Mistake: adding the numbers together. The task says "combine" visually, not sum them.
- Mistake: missing the circle. Drag the loose circle "o" onto the "8" to form the ∞ infinity symbol. That is the largest number and solves the level.
Walkthrough Notes
The scattered numbers tempt you to sum or pick 99 or 888, but the largest possible value is abstract. The "8" next to a small circle "o" can be combined: 8 on its side plus a circle forms the infinity symbol. Infinity beats every finite number on the screen. The victory line "Positive infinity is the largest!" confirms it. Compare this with adding 99 and 888: any finite sum is still smaller than infinity. The two loose circles are part of the trick; drag the 8 next to one to make the sideways infinity sign.
Why It Works
Most players try to combine the biggest-looking numbers: 888, 99, or 521, or they try to add negatives. But any finite number, no matter how large, can still be exceeded. The word largest implies an unbounded value. The two loose circle 'o' shapes and the 8 are arranged so that rotating the 8 and placing a circle beside it draws the infinity symbol. Infinity is not on the scoreboard; it is greater than every listed number at once. This is why the caption celebrates positive infinity.
