The rules:

Normal sudoku rules do NOT apply

Somedoku: Fill every cell with a digit from 1-9. Digits may (and indeed must) repeat in some rows/columns. In each row N (row 1 at the top to row 9 at the bottom), there are exactly N different digits. In each column N (column 1 on the left to column 9 on the right), there are exactly N different digits.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or unshaded. All prime digits (2, 3, 5, 7) are shaded. All square digits (1, 4, 9) are unshaded.

Sum Lines: On each blue line and on each pink line, the sum of shaded cells is equal to the sum of unshaded cells.

Kropki: Digits in cells separated by a black dot have a 2:1 ratio. Not all dots are necessarily given.

German Whispers: On green lines, adjacent cells along the line have digits that differ by at least 5.
