       Divide the grid into regions of orthogonally connected cells, each containing a connected group of white cells and a connected group of grey cells, with the property that the shape of the white cells is identical to the shape of the grey cells, allowing rotations and reflections. Clued cells must belong to a region containing the indicated number of white cells and the indicated number of grey cells. Solve online

    This idea for a hybrid is something I wasn't sure would be possible at all, but it actually wasn't all that difficult to construct and I'm very satisfied with the result.      Place stars into some cells such that each row, column, and outlined region contains exactly two stars. Stars may not touch one another, not even diagonally. Additionally, d raw a non-intersecting loop through the centers of all empty cells which passes through each region exactly twice. Solve online

       Divide the grid into square regions of orthogonally connected cells and s hade some cells so that each region is either fully shaded or fully unshaded.  Region borders may not form any four-way intersections.  Clues represent how many of the five cells forming a cross around the clue (including itself) are shaded. Two shaded squares may not be orthogonally adjacent. Two shaded squares of the same size may not have a vertical or horizontal line of unshaded cells between them, unobstructed. Solve online

       Place a number from 1 to N into each cell so that each row and column contains every number from that range with no repeats, where N is the side length of the grid. A clue outside the grid represents how many cells in the corresponding row or column contain a larger number than all cells before it in that row or column from the direction of the clue.

       Draw rectangular loops through the centers of cells so that every cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. When a loop goes through a black circle, it must turn and travel straight through the cells on either side. When a loop goes through a white circle, it must go straight through and turn in at least one of the cells on either side. Solve online

    Not to toot my own horn, but each time I revisit this genre I'm surprised how much I like it! I hope you enjoy the deductions hidden in this puzzle.        Divide the grid into 1x2 and 1x3 regions. Borders must separate two different regions. Borders with white dots separate regions with the same size and orientation. Borders with black dots separate regions with neither the same size nor the same orientation. Borders with grey dots separate regions with either the same size or the same orientation, but not both. Solve online

      Here's another big loop genre mash-up!     Draw a non-intersecting loop through the centers of some cells so that the rules of each genre are met.     Country Road (Top left):     Each Country Road region must be passed through exactly once.  A number in a region represents how many cells in the region are visited by the loop. Orthogonally adjacent cells in different Country Road regions may not both be unused.     Balance Loop (Top right):     The loop must pass through each 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 number in a circle represents the sum of the lengths of these two line segments.     Disorderly Loop (Bottom left):      Clued cells may not be used by the loop. Clues represent the lengths of the next N line segments appearing in t...

       Divide the grid into square regions of orthogonally connected cells. Borders must separate two different squares. A number on a border indicates the sum of the side lengths of the squares it separates. Region borders may not form any four-way intersections. 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

       Shade some cells to form a non-intersecting path which does not touch itself orthogonally. Circles mark the ends of the path. Exactly one orthogonally connected area of unshaded cells must exist of each size from the range given outside the grid. Cells with numbers cannot be shaded, and represent the size of the area they’re in. 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

       This is a Nurikabe puzzle that works and has a different solve path no matter how many layers you chop off the edges.      Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and every orthogonally connected area of unshaded cells contains exactly one clue, the value of which represents the size of the area. No 2x2 region may be entirely shaded.

       Shade one tetromino of cells in each region so that all shaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded. Two tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same. 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

       Connect some pairs of orthogonally adjacent dots to form paths connecting pairs of circles. Each path must turn exactly once, and each path must be crossed exactly once by another path. Two perpendicular line segments may intersect each other, but not turn or stop at their intersection or otherwise overlap. Two circles containing the same letter must be ends of the same path. Two circles containing different letters may not. Solve online

       Recently I went on a genre-inventing spree, and now I have three more finalized ones that I'm ready to share, the second being Disorderly Loop!      Draw a non-intersecting loop through the centers of some cells. Clued cells may not be used by the loop. Clues represent the lengths of the next N line segments appearing in the loop, not necessarily in order, starting with a line in the cell adjacent to the clue in the direction of its arrow and moving in the direction of the arrow, where N is the amount of numbers in the clue. Solve online

       Shade some cells to form a non-intersecting path which does not touch itself orthogonally. Circles mark the ends of the path. Each orthogonally connected area of unshaded cells must be exactly five cells in size. Clues cannot be shaded, and contain the letter associated with the pentomino shape of their unshaded area. Solve online

       Shade some cells to form a non-intersecting path which does not touch itself orthogonally. Circles mark the ends of the path. Exactly one orthogonally connected area of unshaded cells must exist of each size from the range given outside the grid. Cells with numbers cannot be shaded, and represent the size of the area they’re in. Solve online

     Star Battle (Left):      Place stars into some cells such that each row, column, and outlined region contains exactly N stars. The value of N is given outside the grid. Stars may not touch one another, not even diagonally.      LITS (Right):      Shade one tetromino of cells in each region so that all shaded cells form one orthogonally connected area. Two tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same. No 2x2 region may be entirely shaded.

       Place a number from 1 to N into each cell so that each row and column contains every number from that range with no repeats, where N is the side length of the grid. All pairs of orthogonally adjacent cells containing numbers with a 1:2 ratio are marked with a black dot. All pairs of orthogonally adjacent cells containing consecutive numbers are marked with a white dot. A 1 next to a 2 may be marked with either dot.
