Normal sudoku rules apply: place the digits 1-9 once in each row, column and 3*3 box.

There are exactly one "doubler" cell in each row, column and 3*3 box. The 9 "doubler" cells contain a set of 1-9. The value of the digit in "doubler" cell is twice its original value, while the digit not in "doubler" cell has value equal to itself.

Maximum cell: the value in a maximum cell (gray cells with brackets pointing outwards) is greater than the values in the four orthogonally-connected cells.

Minimum cell: the value in a minimum cell (gray cells with brackets pointing inwards) is smaller than the values in the four orthogonally-connected cells.

Killer cages: values in each killer cage must sum to the number given on the upper left corner of the cage.

Modulo line: any set of three sequential cells along the teal line must contain one value X which yields X mod 3 = 0; one value Y which yields Y mod 3 = 1; and one value Z which yields Z mod 3 = 2.
