Rules: Shade some cells to form a non-intersecting loop which does not touch itself, not even diagonally. Exactly half the cells in each cage are shaded.

Rules: Shade some empty cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. No complete loop of cells may be unshaded (including 2x2s). An arrow indicates the only direction in which one could begin a path to the star without going through a shaded cell or backtracking Variant: Exactly one arrow clue in each region is incorrect (that is, facing the wrong direction)

Rules: Shade some cells so that all areas of orthogonally connected shaded cells are rectangular and all areas of orthogonally connected unshaded cells are not rectangular. A clue represents the size of its group of shaded/unshaded cells.

Rules: From each arrow, draw a path through the centers of cells. The path must begin by moving one cell in the direction of the arrow, but may move in any orthogonal directions afterward. Each path must be either three or four cells long (not including the cell with the arrow) and every cell must be visited by exactly one path.

Rules: Place numbers from the range given outside the grid into some cells so that each row and column contains each number once. When two numbers touch vertically, the one on top must be larger.

Rules: Divide the grid into regions of orthogonally connected cells. Each region must contain exactly one white and one black clue. Black clues indicate the total area of the largest rectangle fully contained within the region. White clues indicate the total area of the smallest rectangle containing the entire region.

Rules: Shade some empty cells so that the remaining unshaded cells form one orthogonally connected area. No complete loop of cells may be unshaded (including 2x2s). An arrow indicates the only direction in which one could begin a path to the star without going through a shaded cell or backtracking Variant: Shade dominoes of cells such that no two dominoes are orthogonally adjacent

Rules: Draw a non-intersecting loop that moves orthogonally through the centers of some cells, and shade the remaining cells such that no two shaded cells are orthogonally adjacent. Clues cannot be shaded nor passed through by the loop, and, if given, indicate the number of shaded cells in the indicated direction between the clue and the edge of the grid.

Rules: Shade one tetrahex of cells in each region so that all shaded cells form one orthogonally connected area. Two tetrahexes of the same shape may not touch orthogonally, counting rotations and reflections as the same. No three shaded cells may meet at a vertex (i.e. any 'triangle' of 3 cells cannot be entirely shaded).

Rules: Place the given fleet of ships into the grid so that no two ships are touching, not even diagonally. Rotating ships is permitted. A clue outside the grid indicates the number of cells in the corresponding row or column that are occupied by ships. Cells with waves cannot be occupied by a ship. A given ship segment must be used as the part of a ship that its shape represents.

Rules: Connect some pairs of orthogonally adjacent dots to form a single loop. Two perpendicular line segments may intersect each other, but not turn at their intersection or otherwise overlap. The loop and the grid boundary divide the grid into regions. Large number clues indicate the total number of cells in the region they are contained in. Small number clues indicate the minimum number of times one must cross the loop to trace a path from the clue to the outside of the grid.
