Hashiwokakero - Rules

Rules

Hashiwokakero is played on a rectangular grid with no standard size, although the grid itself is not usually drawn. Some cells start out with (usually encircled) numbers from 1 to 8 inclusive; these are the islands. The rest of the cells are empty.

The goal is to connect all of the islands by drawing a series of bridges between the islands. The bridges must follow certain criteria:

  • They must begin and end at distinct islands, travelling a straight line in between.
  • They must not cross any other bridges or islands.
  • They may only run perpendicularly.
  • At most two bridges connect a pair of islands.
  • The number of bridges connected to each island must match the number on that island.
  • The bridges must connect the islands into a single connected group.

Famous quotes containing the word rules:

    Here was a place where nothing was crystallized. There were no traditions, no customs, no college songs .... There were no rules and regulations. All would have to be thought of, planned, built up, created—what a magnificent opportunity!
    Mabel Smith Douglass (1877–1933)

    The young break rules for fun. The old for profit.
    Mason Cooley (b. 1927)

    If you do not regard feminism with an uplifting sense of the gloriousness of woman’s industrial destiny, or in the way, in short, that it is prescribed, by the rules of the political publicist, that you should, that will be interpreted by your opponents as an attack on woman.
    Wyndham Lewis (1882–1957)
