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...
