      Here are three relatively simple 9x10 Masyu puzzles with symmetrical layouts. The third is a bit trickier than the other two.      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.

       Draw a non-intersecting loop through the centers of some cells which visits each shaded region at least once and passes through every circle. 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).  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

     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.  Each orthogonally connected area of cells not used by the loop must be in the shape of a square. Two unused squares of the same size may not have a vertical or horizontal line of used cells between them, unobstructed. Solve online

      Kropki (Pairs) (Left):      Place a number from 1 to N into each cell so that each row and column contains every digit with no repeats, where N is the side length of the grid. Pairs of orthogonally adjacent cells marked with a black dot must contain numbers with a 1:2 ratio. Pairs of orthogonally adjacent cells marked with a white dot must contain consecutive numbers.     Masyu (Right):      Draw a non-intersecting loop through the centers of some cells that passes through every circle.
