The first diagram is a standard U-Bahn. Draw a loop network through the centers of some cells, which may branch or turn, but may not have any dead ends. A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.

The second diagram is a 6x6 killer sudoku. Place the numbers from 1 to 6 exactly once in every row, column, and bold outlined region. An area enclosed by a dashed line is called a killer cage. Numbers in a killer cage must be different and sum to the number in the upper-left corner of the cage.

The third diagram indicates exactly how many times that shape piece appears in the same relative cell as the sudoku.
