5 × 3Scroll sideways if you cannot see every column.
Available dominoes: Piece 1: 4-2; Piece 2: 5-1; Piece 3: 6-5; Piece 4: 6-2; Piece 5: 4-5.
Where to look
Area 2 has 1 cell: Sum = 2. Look at row 1, column 3.
A local clue for Area 1
The two cells in Area 1 must total 8. Using values from 0 to 6, the possible pairs are 2 + 6; 3 + 5; 4 + 4.
Other areas and the available dominoes may rule out some of these pairs.

Each outlined pair is one piece. Piece numbers identify the same domino in the list below, including when two pieces have the same values.
- Piece 1 (4 | 2): horizontal; row 1, column 2 = 4, paired with row 1, column 3 = 2.
- Piece 2 (5 | 1): horizontal; row 3, column 2 = 5, paired with row 3, column 3 = 1.
- Piece 3 (6 | 5): vertical; row 4, column 1 = 6, paired with row 3, column 1 = 5.
- Piece 4 (6 | 2): horizontal; row 5, column 1 = 6, paired with row 5, column 2 = 2.
- Piece 5 (4 | 5): vertical; row 1, column 1 = 4, paired with row 2, column 1 = 5.
Why these area rules are satisfied
- Area 1: Sum = 8. 4 + 4 = 8; target 8.
- Area 2: Sum = 2. 2 = 2; target 2.
- Area 3: Sum = 15. 5 + 5 + 5 = 15; target 15.
- Area 4: No rule. This area has no additional rule.
- Area 5: All equal. 6 = 6: all cells have the same value.
- Area 6: Sum = 2. 2 = 2; target 2.
