       Draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. Orthogonally adjacent cells across a region border may not both be unused.  Clues represent the numbers of consecutive cells occupied by the loop each time it enters the (up to) eight cells surrounding the clue.     The shaded regions are just to accentuate the theme, and act no differently from the unshaded regions.

       Draw a non-intersecting loop through the centers of some empty cells. Clues represent the numbers of consecutive cells occupied by the loop each time it enters the (up to) eight cells surrounding the clue. Solve online

      Draw a non-intersecting loop through the centers of some cells so that the rules of each genre are met.     Masyu (Top left):      The loop must pass through each 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.     Ovotovata (Top right):      The loop must visit each shaded region at least once. When the loop exits a clued region in any direction, it must travel in a straight line for exactly the indicated number of cells (turning on the Nth cell, where N is the value of the clue). A question mark can represent any positive integer.     Yajilin (Bottom left):      The loop may not pass through clued cells. No two empty cells within the bottom left quadrant may share an edge. Clues represent the number of empty cells in a strai...
