Cómo jugar a Sudoku Entre Líneas
Los dígitos en una línea deben caer estrictamente entre los dos valores de los extremos
Las reglas
Se aplican las reglas estándar del Sudoku: rellena cada fila, columna y caja de 3×3 con los dígitos del 1 al 9, cada uno apareciendo exactamente una vez.
Between Lines Sudoku dibuja líneas con extremos circulares. Cada dígito a lo largo de la línea (excluyendo los propios extremos) debe ser estrictamente mayor que el extremo menor y estrictamente menor que el extremo mayor. Si los extremos son 2 y 8, cada celda intermedia en la línea debe ser uno de 3, 4, 5, 6 o 7. Cuanto más cercanos están los extremos en valor, más restringidas están las celdas intermedias.

Preguntas Comunes
¿Qué es Between Lines Sudoku? ▾
Between Lines Sudoku is a variant where lines with circular endpoints are drawn on the grid. Every digit along a line (excluding the endpoint circles) must be strictly between the two endpoint values. The endpoints themselves are placed during solving — only the line positions are given.
How do I read the between-line clues? ▾
The two circles at the ends of each line are the boundary values. Every cell between them must be strictly greater than the smaller endpoint and strictly less than the larger one. You deduce which endpoint is larger as part of the solve.
Can the endpoints be any digits? ▾
Yes. Endpoint circles are not pre-filled — you place digits in them during solving. The only rule is that every cell along the line (excluding endpoints) must sit strictly between whatever ends up in the two circles.
What is the best strategy for Between Lines Sudoku? ▾
Look for short between-lines — a single cell between two endpoints is tightly constrained. Combined with row, column, and box rules, the valid range for that cell is often very small. Also look for lines where available candidates in a given row or column form a narrow range.
Is Between Lines Sudoku hard to learn? ▾
The concept is straightforward but the deductions require careful range analysis. Tracking the minimum and maximum possible values for each endpoint and inferring the valid range for in-between cells is the core skill. Easy puzzles make this very accessible.
How long does Between Lines Sudoku take to solve? ▾
Easy puzzles take 8–18 minutes. Medium puzzles run 18–35 minutes. Hard puzzles average 35–65 minutes and expert puzzles can take over 90 minutes. Solve time scales with the number of overlapping lines and the complexity of range interactions.
