Como jogar Little Killer Sudoku
As pistas fora da grelha dão a soma de uma diagonal
As Regras
As regras padrão do Sudoku aplicam-se: preencher cada linha, coluna e caixa 3×3 com os dígitos 1–9, cada um aparecendo exatamente uma vez.
Little Killer Sudoku coloca pistas fora da grelha juntamente com uma seta diagonal. A seta aponta para uma faixa diagonal de células, e a pista dá a soma de todos os dígitos ao longo dessa diagonal. Ao contrário das gaiolas padrão de Killer Sudoku, os dígitos PODEM repetir-se nas diagonais Little Killer desde que não violem as regras de linha/coluna/caixa. Isto torna a aritmética diferente da resolução padrão de gaiolas.

Perguntas Comuns
O que é o Little Killer Sudoku? ▾
Little Killer Sudoku is a variant where numbers appear outside the grid next to diagonal arrows. Each clue gives the sum of all cells along the diagonal that arrow points into. Unlike Killer Sudoku cages, digits may repeat along a Little Killer diagonal — the only uniqueness constraints are the standard row, column, and box rules.
How is Little Killer different from Killer Sudoku? ▾
In Killer Sudoku, cage digits cannot repeat. In Little Killer Sudoku, diagonal digits can repeat freely — only standard Sudoku uniqueness rules apply. This changes the solving logic significantly: you cannot directly eliminate combinations based on uniqueness within a diagonal.
Can digits repeat along a Little Killer diagonal? ▾
Yes. Digits may repeat along a Little Killer diagonal as long as they are in different rows, columns, and boxes — which standard Sudoku rules enforce. For example, a 3-cell diagonal summing to 6 could be {1,1,4}, {1,2,3}, {2,2,2}, {3,2,1}, etc.
How do I start solving Little Killer Sudoku? ▾
Start with the shortest diagonals. A 1-cell diagonal tells you the digit directly. A 2-cell diagonal with a very small or very large sum severely limits possible combinations. Then look for diagonals that intersect — where the same cell must satisfy two diagonal sum constraints simultaneously.
Is Little Killer Sudoku hard to learn? ▾
The core rule is straightforward. The challenge comes from the arithmetic of diagonal enumeration combined with the fact that digits can repeat. Beginners benefit from writing out all possible combinations for each diagonal before starting to eliminate. This habit makes the variant much more approachable.
How long does Little Killer Sudoku take to solve? ▾
Easy puzzles take 10–20 minutes. Medium puzzles run 20–40 minutes. Hard puzzles average 40–75 minutes and expert puzzles often exceed 90 minutes. Cross-diagonal intersection analysis is the key skill that distinguishes fast solvers from slower ones.
