Normal sudoku rules apply.
Black ovals separate adjacent "Big Numbers" in a row or column with a ratio of 2:1. A Big Number consists of two or more digits in a horizontal or vertical line, read left-to-right or top-to-bottom. In the top row, the 2:1 ratio Big Numbers are marked by cages. Not all possible ovals are given.
Sandwich clues outside the grid show the sum of the digits located between the 1 and 9 in the corresponding row or column.
Cells with grey squares contain even digits.
Inequality symbols (<) between two cells point to the smaller digit.
