Each digit from 1 to 8 must appear eight times in the grid. Some digits from 1 to 8 are sudoku digits and the others are omino digits. All instances of a particular digit are of the same type. For each digit, its type must be determined. A sudoku digit must appear exactly once in every row, column and box. An omino digit indicates the size of its omino (an omino is a group of orthogonally connected cells containing identical omino digits.) Two ominos of the same size may not touch each other - not even diagonally. For a digit in a circle, it indicates exactly how many circles contain that digit. Digits separated by a white dot are consecutive digits.
