Level Overview
What Makes This Puzzle Tricky
Back to algebra class—but without notes or a calculator. You’re faced with a minimalist graph, three floating colored Xs, and a simple prompt: “fill the lines.” It feels like a drawing or connection challenge—until you realize dragging does nothing. This isn’t about sketching. It’s about decoding.
Your Goal
Pinpoint the exact (x,y) position of each colored X on the grid—and enter those two-digit numbers onto their matching colored input lines.
Key Mechanics
- Math Logic (Coordinates): Standard Cartesian plane rules apply—horizontal first, vertical second.
- Observation: Accuracy depends on counting grey axis dots precisely.
- Hidden Keypad: Those colored underlines aren’t decorative—they’re tap-to-type fields. This isn’t art. It’s precision data entry.
What Appears on Your Screen
A sleek dark grey backdrop fills the screen. Centered is a classic L-shaped coordinate axis.
- The Grid: The horizontal (x) axis has 5 evenly spaced dots. The vertical (y) axis also shows 5 dots. Their intersection is the origin.
- The Targets: Three stationary colored X markers hover inside the grid: Red, Blue, and Green.
- The Prompt: A clean header reads “fill the lines.”
- The Input Fields: To the left of the graph sit three color-matched underlines (Red, Blue, Green), stacked vertically and waiting for input.
Common Mistakes to Avoid
The Trap
“Fill the lines” sounds like past levels where “fill” meant dragging objects into place—paint buckets, shapes, or even words. Players instinctively try dragging Xs onto the lines or reshaping the graph itself. But nothing moves. The illusion is strong—and misleading.
First Instincts That Fail
- Drawing connections: Attempting to draw a line from the axis to each X.
- Measuring manually: Pulling out real-world rulers or zooming in excessively.
- Dragging the Xs: They’re fixed—no amount of swiping will budge them.
Player Reactions
I wasted nearly 90 seconds trying to drag the word “lines” onto the graph, convinced it was another sneaky wordplay gag. Nope—it was just basic dot-counting. Felt like flunking middle school math all over again.
Step-by-Step Solution
Preparing the Move
Put down the swipe gesture. Zero in on the L-shaped axis. Set the bottom-left corner—the meeting point—as your (0,0) origin.
Executing the Solution
- Analyze the Red X: Locate the Red X. Count how many dots it sits right of the origin along the x-axis: 1. Then count how many dots it sits up from the origin along the y-axis: 2. Coordinate = (1, 2).
- Input Red: Tap the Red underline. When the keypad appears, enter 12.
- Analyze the Blue X: Find the Blue X. It’s 4 dots right and 4 dots up → (4, 4).
- Input Blue: Tap the Blue underline and type 44.
- Analyze the Green X: Spot the Green X. It aligns with 3 dots right and 1 dot up → (3, 1).
- Input Green: Tap the Green underline and type 31.
If It Did Not Work
- My keypad won't open: Tap directly on the colored line—not the blank space beside it or the label above.
- Is it X first or Y first? Yes—always horizontal (x) before vertical (y). Entering “21” instead of “12” will fail.
- Zero Indexing: The corner dot is (0,0). The first dot to the right or up is “1”—not “0.”
Why This Solution Works
This level flips the script: after layers of creative, offbeat puzzles, it drops a straightforward academic test. No gimmicks—just clean coordinate logic. The missing grid lines force you to visually project alignment, making observation as critical as math.
Bonus Tip
For speedrunners or anyone tired of pixel-perfect squinting:
- Red always equals 12
- Blue always equals 44
- Green always equals 31
Skip the visual guesswork—type and go.
Frequently Asked Questions
Q: Do I need to put a comma between the numbers in Game is hard Level 108? A: No. Enter digits back-to-back—12, not “1,2”.
Q: Why is the corner not counted as “1”? A: Because graphs start at (0,0). Each dot represents one unit away from that origin.
Q: I typed the numbers but nothing happened in Game is hard Level 108? A: Confirm you tapped the checkmark or “Enter” on your keyboard—the level waits for submission confirmation.
Q: Can I solve them in any order? A: Absolutely. Enter Green first, Red last—it doesn’t matter. Victory triggers once all three correct codes are submitted.
