1. Sudoku.
Place the digits 1-9 in every row, column and box exactly once each.
2. Region sum lines.
Digits on the blue lines have an equal sum in each box through which the line passes.
3. Killer cages.
Digits in cages sum to the total given in the corner.
4. Diagonals.
Digits on the given diagonals do not repeat.
