How to Solve LinkedIn Tango Puzzle: Expert Line Drawing Strategies

Tango Puzzle Rules Explained
Tango presents a grid of colored dots. Your goal: draw lines connecting all dots of the same color without lines crossing. Each color family must be perfectly balanced - the number of "ends" on left/right and top/bottom must match.
The challenge lies in the global constraint: your local line choices must satisfy the overall balance requirements.
Core Strategy: Balance Counting
Before drawing any lines, count endpoints per direction:
- Left column dots needing rightward lines
- Right column dots needing leftward lines
- Top row dots needing downward lines
- Bottom row dots needing upward lines
If left endpoints ≠ right endpoints for a color, immediate contradiction!
The Triple Rule (Advanced Technique)
When three dots of the same color form a triangle pattern, they must connect in a specific way:
Triangle Pattern → One central line connecting all three + outer loop
Dead-End Avoidance
- Avoid "trapping" isolated dots
- Check neighbor counts before connecting
- Use "forced moves" - dots with only one possible direction
Complete Solving Algorithm
- Count balance for all colors
- Identify forced single-direction dots
- Draw all possible non-crossing connections
- Verify global balance satisfied
FAQ
Can lines touch at endpoints only?
Yes, multiple lines can share endpoints but cannot cross or overlap segments.
What if balance doesn't match?
Your line drawing created an imbalance. Backtrack and find alternative routing.
