Normal Sudoku rules apply.

Arrow - Digits along an arrow must add up to the total given in the attached circle.

Killer cages - The grid contains “cages” of any number of cells, indicated by dotted lines. Digits cannot repeat within a cage, and the digits within a cage must add up to the total given in that cage’s upper-left corner.

Kropki dots - A white dot separates two digits that are consecutive. A black dot separates two digits such that one is twice the other.

Little killer - Clues outside the grid (with diagonal arrows) give the sum of the digits along the indicated diagonal.
