Guía interactiva

When two clues leave only a few numbers between them, fewer routes can connect them.
Consecutive values may touch at a corner, not only along an edge.
Solve the most constrained section first even if it is far from 1.
Conecta parejas iguales con caminos que no se crucen.
Traza un único camino que visite los checkpoints en orden y cubra toda la cuadrícula.
Traza una vía continua entre las salidas usando los recuentos de filas y columnas.
