How to Get Started
UNDERSTANDING THE RULES (10 minutes)
Grid structure: White cells for numbers (1-9), shaded cells contain sum clues
The goal: Fill white cells so each run adds to the clue number
No repeats: Within each run, no digit appears twice
Example: Clue '10 in 2' could be 1+9, 2+8, 3+7, or 4+6
BASIC STRATEGIES (15 minutes)
Learn combinations: Memorize common sums (3 in 2 = 1+2 only, 17 in 2 = 8+9 only)
Start with limits: Two-cell runs with extreme sums have few options
Cross-reference: Where runs intersect, numbers must satisfy both clues
Elimination: Use Sudoku-like logic to eliminate impossible numbers
