Bag (puzzle)
From Wikipedia, the free encyclopedia
Bag is a binary-determination logic puzzle published by Nikoli.
[edit] Rules
Bag is played on a rectangular grid, usually of dashed lines, in which numbers appear in some of the cells.
The object is to draw a single, continuous loop along the lines of the grid, which contains all the numbers on the grid. Additionally, each number denotes the sum of all cells visible in any orthoganal direction before line of the loop is reached. For example, a 2 cell will have one cell adjacent to it, followed by a wall of the loop.
[edit] Solution methods
Many of the solution methods for Bag are very similar to those used for Where is Black Cells, as the rules are also very similar. The most notable difference is the use of the loop as a part of the solution, as opposed to shaded cells.
