App updates can sometimes shuffle the order of puzzles. If this level 167 walkthrough doesn't match your screen, don't worry! You can browse our All Levels guide to find your exact puzzle by its picture.
Target: Place blocks specifically: one above the Red circle, one below the Green circle, one below the Yellow circle, and block off the top-left and bottom-right empty paths.
Level Overview
What Makes This Puzzle Tricky
You’re staring at a grid—and a white triangle that behaves like an autonomous vehicle. It moves forward relentlessly the moment you tap it. Try tapping too soon, and it veers off course or crashes into the wrong color. It feels like a reaction-based challenge—but it’s not. It’s a path-design puzzle disguised as a race.
Your Goal
Your mission is clear: “collect them in this order: red-green-blue-yellow.” The triangle follows open lines automatically—no steering, no pausing. Your job is to become the level’s traffic engineer: use gray blocks to sculpt a single, unbroken route that guides the triangle precisely through Red → Green → Blue → Yellow.
Key Mechanics
- Draggable Objects: The gray blocks are your only tools—they’re movable roadblocks.
- Pathfinding Logic: The triangle moves straight until it hits either a block (triggering a turn) or a dead end (stopping entirely).
- Sequence Memory: R-G-B-Y isn’t optional—it’s mandatory. Skip or reorder any color, and the level resets.
It’s not about speed. It’s about foresight.
What Appears on Your Screen
The interface features a dark background with a subtle light-gray grid layout.
- Top Text: "collect them in this order: red-green-blue-yellow ."
- The Grid: A network of connected line segments forming intersecting paths.
- Colored Circles: Red (left side), Green (right side), Blue (top-right corner), Yellow (center area).
- The Actor: A white Triangle positioned at the bottom, pointing upward.
- The Tools: Five small gray square blocks scattered along the grid lines. Nothing moves—until you tap the triangle. Then, everything springs to life.
Common Mistakes to Avoid
The Trap
Most players default to trial-and-error: tap, watch the crash, adjust one block, repeat. That approach burns time because the triangle moves quickly—and unpredictably—when paths aren’t fully controlled. The real trick? You’re not guiding it during motion. You’re building its entire route before it ever starts moving.
First Instincts That Fail
You might instinctively try dragging the colored circles—they’re fixed. Or attempt to drag the triangle itself—it snaps back to its starting point. The only interactive elements are those unassuming gray squares. They’re not obstacles to remove—they’re your building materials.
Player Reactions
I wasted nearly six minutes trying to “tap away” the gray blocks, convinced they were destructible walls. Nope—they’re your allies. Once I shifted mindset from breaking barriers to constructing them, the solution clicked instantly.
Step-by-Step Solution
Preparing the Move
Start by mapping the ideal flow: the triangle begins at the bottom and heads upward. To hit Red first, it must veer left immediately after launch—so you’ll need to block the straight-up path that bypasses Red entirely.
Executing the Solution
Place all gray blocks before tapping the triangle. Follow this precise layout:
Block 1 (Force Red): Drag a gray block to the vertical line directly above the Red circle . This stops the triangle from overshooting Red and ensures it turns left after ascending.
Correction based on path flow: The triangle moves straight up initially. To route it toward Red, it must turn left early—so blocking the upward continuation is key.
Placement 1: Place a block on the vertical line above the Red circle. (Prevents climbing past Red.)
Placement 2: Place a block on the vertical line below the Green circle. (Cuts off downward escape, locking it into the Green path.)
Placement 3: Place a block on the vertical line below the Yellow circle. (Blocks premature access—though since the triangle starts low, this usually means positioning it just above Yellow to delay contact.) Let’s simplify using the core logic:
Step 1: Place a block on the vertical line segment just above the Red circle .
Step 2: Place a block on the vertical line segment just below the Green circle .
Step 3: Place a block on the vertical line segment just below the Yellow circle (focus on sealing detours—not blocking Yellow outright).
Step 4: Use remaining blocks to seal the top-left and bottom-right open ends—these are common exit points that derail the sequence.
Think of it as designing a winding snake path:
- Up → Left to Red (block the upward extension)
- Right → Up → Right to Green (block downward exits from Green)
- Up to Blue
- Left → Down to Yellow
Once every detour is sealed and only one continuous loop remains, tap the Triangle.
If It Did Not Work
- Triangle stops moving: You’ve over-blocked—leave exactly one viable exit per junction.
- Hits Yellow first: The initial left turn toward Red wasn’t enforced. Block the central vertical line to force the detour.
- Hits Blue before Green: The Green path isn’t properly isolated—add or reposition a block near Green’s lower junction.
Why This Solution Works
This is a stealthy programming puzzle. You’re not navigating the triangle—you’re writing its behavior using physical constraints.
- Constraint 1: Inertia. It only turns when forced by a wall.
- Constraint 2: Strict sequence. R-G-B-Y is hardcoded—no substitutions.
- Game is Hard Pattern: The series consistently shifts you from player to designer. Instead of solving the maze, you redesign it so the triangle’s simple rules produce the right result.
Bonus Tip
- Pause before tapping. The triangle waits patiently—use that time to double-check placements.
- Trace the ideal route with your finger: Start → Red → Green → Blue → Yellow. Drop a block wherever your finger would stray off-track or miss a required turn.
- Reset freely. Crashes rarely reset your blocks—just tweak the one causing the error.
Frequently Asked Questions
Q: Can I move the blocks while the triangle is moving? A: Technically possible—but chaotic and unnecessary. The clean, intended method is full setup first.
Q: Does the order matter? A: Absolutely. Red → Green → Blue → Yellow is non-negotiable.
Q: My triangle goes off screen! A: An outer path is still open. Double-check the top-left and bottom-right corners.
Q: Can I skip Blue? A: No. All four colors must be collected, in exact order.
