Regole che si applicano alle diagonali o alle celle d'angolo della matrice.
Beyond rows and columns, matrices can have diagonal rules. The main diagonal runs from top-left to bottom-right; the anti-diagonal runs from top-right to bottom-left. Corner rules specifically match the four corner cells. These patterns are typically found in harder puzzles and require looking beyond the obvious row/column structure.
Diagonal: cells[0,0], cells[1,1], cells[2,2] share attribute. Corners: cells at (0,0), (0,2), (2,0), (2,2) share attribute.
- Diagonal shape: Top-left, center, bottom-right all have same shape
- Anti-diagonal fill: Top-right, center, bottom-left all have same fill
- Corners same: All four corner cells have matching shapes
Come riconoscerlo
- After checking rows and columns, examine the diagonals
- Compare the four corner cells for matching attributes
- Diagonal rules often combine with row/column rules
- These patterns appear in harder difficulty levels
Errori comuni
- Only checking rows and columns, missing diagonal patterns
- Confusing main diagonal with anti-diagonal
- Forgetting that diagonal rules can apply to any attribute
Soluzione passo per passo
In una matrice 3x3, tutte le celle sulla diagonale principale condividono la stessa forma. Le celle 1 e 5 contengono cerchi. Manca la cella 9. Quale forma corrisponde?
- Identificare le celle della diagonale principale
- Verificare il pattern diagonale: la cella 1 ha un cerchio
- Confermare il pattern: anche la cella 5 ha un cerchio
- Applicare la regola diagonale alla cella 9
Risposta: Cerchio
