       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

       Divide the grid into regions of orthogonally connected cells. Two regions of the same size may not share an edge. Clued cells must belong to a region containing the indicated number of 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. 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.

       Connect some pairs of orthogonally adjacent dots to form a single non-intersecting loop. Clues represent the number of edges drawn surrounding the clue (up to four). Additionally, write a number into each shaded cell. These numbers act the same as given clues. Cells in the same position in corresponding shaded regions must contain the same number. Solve online

       Shade some dominoes of cells to divide the grid into unshaded areas. Shaded dominoes may not touch orthogonally. Clues cannot be shaded, and each orthogonally connected area of unshaded cells contains exactly one type of clue, and all instances of it. Solve online

       Place a number into some cells so that all cells with numbers form one orthogonally connected area. Numbers represent how many numberless cells are connected to them in a straight line horizontally or vertically. No two orthogonally adjacent cells may contain the same number. Solve online

       Shade some cells so that clues represent the total size of the orthogonally connected areas of shaded cells that share an edge with the clue. Clued cells cannot be shaded. Areas of shaded cells must all be different sizes. 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. 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.

       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 so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid.      To be clear, the rule from Tapa which states that a 2x2 area cannot be entirely shaded does not apply. Solve online

       Shade some cells so that no two shaded cells are orthogonally adjacent and draw rectangular loops through the centers of the remaining empty cells so that every remaining empty cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. Clues cannot be shaded, and represent the number of shaded cells in a straight line in the indicated direction. Solve online

       Draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. Within a region, the loop must pass through all moons and no suns, or all suns and no moons. A region containing only suns or only moons must have its clues passed through. The loop may not pass through the same type of clue in two consecutively used regions. Solve online

       Shade some cells so that the remaining unshaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded or unshaded. Circles mark every instance of a cell which is unshaded and orthogonally adjacent to exactly one other unshaded cell. If a circle contains a number, it indicates how many cells are in the straight line of unshaded cells coming out of the cell with the circle, including itself. Solve online

      Here's a puzzle I made for a speed-setting contest in the CTC Discord server.      Draw a non-intersecting loop through the centers of all cells. 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.
