Petunjuk memberikan jumlah digit antara 1 dan 9 di setiap baris/kolom

Apa itu Sandwich Sudoku?

Sandwich Sudoku menempatkan petunjuk di sepanjang bagian luar kisi. Setiap petunjuk memberikan jumlah semua angka yang terjepit di antara 1 dan 9 di baris atau kolom tersebut. Posisi 1 dan 9 bervariasi, sehingga 'sandwich' dapat memiliki 0 hingga 7 sel tergantung di mana mereka mendarat. Petunjuk 0 berarti 1 dan 9 berdekatan. Petunjuk 35 berarti semua angka 2โ€“8 berada di antara mereka.

Pertanyaan yang Sering Diajukan

Apa itu Sandwich Sudoku?
Sandwich Sudoku is a variant where clue numbers appear outside the grid, one per row and one per column. Each clue tells you the sum of all digits that appear between the 1 and the 9 in that row or column. Standard Sudoku rules apply throughout.
How do I use the sandwich clues?
First, find the positions of the 1 and 9 in each row or column โ€” every other digit between them must sum to the outside clue. A clue of 0 means the 1 and 9 are adjacent. A clue equal to the maximum possible sum (e.g., 35 for a 7-cell sandwich) tells you the 1 and 9 are at the ends. Work from the most constrained clues first.
Apa arti sandwich clue 0?
A clue of 0 means no digits are sandwiched between the 1 and 9 โ€” they must be directly adjacent to each other. This is one of the most powerful clues because it immediately tells you where 1 and 9 can and cannot be placed relative to each other in that row or column.
Is Sandwich Sudoku harder than regular Sudoku?
Yes, generally. Sandwich Sudoku provides very few pre-filled digits inside the grid. Almost all deductions flow from working out where 1 and 9 can sit and what sums are achievable. The logic is more algebraic than classic Sudoku, which many players find both more challenging and more satisfying.
Can the 1 and 9 be at the ends of a row?
Yes. If the 1 is in column 1 and the 9 is in column 9 (or vice versa), the sandwiched digits are columns 2โ€“8, giving a maximum possible sum of 2+3+4+5+6+7+8 = 35. Extreme clue values like this immediately fix the positions of both the 1 and the 9.
How long does Sandwich Sudoku take to solve?
Easy puzzles typically take 10โ€“20 minutes. Medium puzzles run 20โ€“35 minutes. Hard puzzles can take 45โ€“75 minutes, and expert puzzles often exceed 90 minutes. The key bottleneck is working out 1/9 positions โ€” once you pin those down, the rest of the grid often resolves quickly.

Both are sum-deduction puzzles at heart โ€” killer's 45 rule and sandwich's crust sums exercise the same arithmetic.
