       Divide the grid into dominoes and place a two-cell-long arrow in each one. The dominoes must all form a single continuous loop, where each domino’s arrow points to the next. Solve online

       Draw a non-intersecting path through the centers of some cells which passes through every white circle and every letter, but not through any black circles. Grey circles mark the ends of the path. Starting from one grey circle,  the path must travel through the letters in the given password, in order, repeatedly until the second grey circle is reached.  Between each pair of circles the path uses, the path must turn exactly twice, and both turns must be in the same direction. Solve online

       Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a rectangle and the remaining unshaded cells form one orthogonally connected area. Clued cells cannot be shaded, and represent the total size of the shaded rectangles that share an edge with the clue. If a clue has no number, it must share an edge with at least one shaded rectangle. Solve online

       Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a square and the remaining unshaded cells form one orthogonally connected area. Numbered regions must contain the indicated amount of shaded cells. A line of consecutive unshaded cells may not cross more than one bold border. Solve online

       Draw a non-intersecting path through the centers of all cells, starting from the S (start) and finishing at the G (goal). Each numerically clued cell must be traveled through on the path’s Nth visit to the region the clue lies within, where N is the value of the clue.  The straight line segments coming out of a white circle must have equal length, while the straight line segments coming out of a black circle must have different lengths. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area.  No 2x2 area may be entirely shaded.     Canal View (Left and right):     Clues inside the grid cannot be shaded, and represent the number of shaded cells connected in a straight line horizontally or vertically to the clue.     LITS (Middle):    Each of the six regions in the middle part of the grid must contain one tetromino of shaded cells.  Two of these tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same.     Cross the Streams (Whole grid):      Clues outside the grid represent the lengths of the blocks of consecutive shaded cells in the corresponding row or column, in order. A question mark represents one block of an unknown number of cells. An asterisk represents any number of blocks of shaded cells, including none at all. Solve online

       Draw a non-intersecting path through the centers of all cells, starting from the S (start) and finishing at the G (goal). Each clued cell must be traveled through on the path’s Nth visit to the region the clue lies within, where N is the value of the clue. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area. Numbered regions must contain the indicated amount of shaded cells. The shaded cells within a region must have 180° rotational symmetry around the region's center. No 2x2 area may be entirely shaded. Solve online

       Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a square. Clues represent how many of the five cells forming a cross around the clue (including itself) are shaded. Two shaded squares of the same size may not have a vertical or horizontal line of unshaded cells between them, unobstructed. Solve online

       Draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. A number in a region represents how many cells in the region are visited by the loop. Orthogonally adjacent cells across a region border may not both be unused. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The straight line segments coming out of a white circle must have equal length, while the straight line segments coming out of a black circle must have different lengths. A clue in a circle represents the sum of the lengths of these two line segments. Solve online

       Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a square and the remaining unshaded cells form one orthogonally connected area. Clued cells cannot be shaded, and represent the total size of the shaded squares that share an edge with the clue. If a clue has no number, it must share an edge with at least one shaded square. Solve online

       Draw a non-intersecting path through the centers of all cells, starting from the S (start) and finishing at the G (goal). Each clued cell must be traveled through on the path’s Nth visit to the region the clue lies within, where N is the value of the clue. Solve online Solve online

       Place letters from the range given outside the grid into some cells so that each row and column contains each letter once. A clue outside the grid represents the first letter seen in the corresponding row or column from that direction. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. Solve online

       Locate some blocks in the grid, each of which are either 1x2 or 1x3, which may not overlap each other. Each clue must be used by a block and each block must contain exactly one clue, the value of which represents how many different locations to which the block can be moved by sliding it in the direction of its short end without overlapping another block or going out of the grid. Staying stationary does not count as one of these locations. Solve online

    Here's another puzzle with a "Powers of 2" theme!        Place a number from 1 to N-2 into some cells so that each row and column contains every number from that range with no repeats, where N is the side length of the grid, and shade the remaining two cells of each row and column. A clue outside the grid indicates the sum of the digits which appear between the two shaded cells in the corresponding row or column. Solve online

       Shade some dominoes of cells so that every region contains exactly two shaded cells. Shaded dominoes may not touch orthogonally. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. The loop may not make two turns in the same direction in two consecutively used cells. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. No two unused cells may share an edge. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. No two consecutive straight line segments may be the same length. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles. No straight line segment may be more than two cells in length. Solve online
