Cómo se juega

Each row is a category and contains each of its symbols exactly once.
Columns are positions: use the clues to decide which symbol from every category occupies each position.
Select a cell and eliminate candidates from the tray; when only one remains, that position is resolved.
Every clue is true and every generated puzzle has one proven solution that can be reached without guessing.

Start with fixed-position, same-column and adjacency clues because they often trigger several eliminations.
If a symbol can appear in only one position of its row, that position is determined even if other candidates are still visible there.
Combine clues: a negative relation often becomes useful after a more direct relation has narrowed the options.
On Hard and Expert, look for chains of two or three clues before eliminating a candidate.
