Tips & Tricks

Start with clues that have limited number combinations, like 3 can only be 1+2 or 4 can only be 1+3.
Use the constraint that numbers can't repeat in a single clue group to eliminate possibilities quickly.
Work on intersecting clues together—when a cell belongs to both a row and column clue, use both constraints to narrow
Tackle the harder levels after mastering earlier ones to build confidence and pattern recognition skills.
