Puzzles/Shading

Shade grid puzzles are named as such due to in order to solve the puzzle shading the grids is a must. Below are types of shading puzzles

Rules

 * Certain cells are shaded so that each number indicates total number of cells that are "visible"/ unshaded cells in the same row and column, including cells itself
 * No cells with number can be shaded
 * Shaded cells cannot touch except diagonally
 * All unshaded cells must form a single continuous area, you can travel horizontal and vertically from cells to cells

Rules

 * Shade rectangular group of cells so that each group is at least 2 cells wide and at least 2 cells tall ( > 2X2)
 * Each shaded rectangular cannot touch at all even diagonally
 * The number given is the number of shaded cells in each rows and columns

Rules

 * Place light bulbs in some empty cells so that each empty cells is illuminated
 * Light bulbs illuminate every cell in their row and column until being blocked by black cell
 * No light bulb can be illuminated by other light bulb
 * Some black cells have number, corresponding to the number of touching, non diagonally cells

Rules

 * Shade some grid cells, which may include the numbers printed on them
 * A number in cell reveal the number of shaded touching cells, including touching diagonally and the cell itself
 * The finished puzzle will reveal a simple picture

Rules

 * Shade some grid cells, so that no 2 shaded cells are adjacent (except diagonally) and unshaded cells forming single continuous area
 * Any single horizontal or vertical group of unshaded cells cannot cross more than one bold line region
 * Number cells may or may not be shaded but it always gives the precise amount of shaded cells inside the bold line region

Rules

 * Shade some cells to form contiguous shaded region
 * Numbers in a cell reveal length of each group of touching shaded cells (Including diagonally touching cells)
 * If there are more than one number in a cell, meaning there must be at least one unshaded cell
 * Shaded cell cannot form 2X2 square or larger

Rules

 * Place mines into empty cells in the grid
 * Number in the cells meant that humber of mines touching the cells itself (including diagonally)
 * Only one mine may be placed per cell

Rules

 * Shade some cells to form a single snake that starts and ends at the given cells
 * The "snake does not cross over itself
 * The snake does not touch itself (even diagonally, except when turning cornet)
 * Number outside the grid specify number of cells in row/column contain part of the snakes

Rules

 * Shade some cells so that no numbers repeat in any row of column
 * Shaded cells cannot touch except diagonally
 * All shaded cells must form a single unconnected region

Rules

 * Shade some cells so that every numbers in the puzzle remain as part of continuous unshaded rectangle of precisely the given cells
 * Shaded cells cannot form areas larger than 2X2
 * Not all unshaded rectangles are necessarily marked with numbers
 * In this puzzle, rectangle can meant square too.

Rules

 * Place stars in some cells so that each row, column and outlined region contains exactly two stars
 * Stars cannot touch each other, not even diagonally
