Advent Sudoku


Like the conventional Sudoku, this Advent Calendar Sudoku consists of a grid of nine rows and nine columns subdivided into nine 3x3 subgrids.

However, rather than containing the numbers 1 to 9, this sudoku contains the nine different letters which are used in the words "Advent Calendar".

There are still two basic rules:

1. Each column, each row, and each box (3x3 subgrid) must have each of the nine letters (A, C, D, E, L, N, R, T, V).

2. No column, row or box can have two squares with the same letter.
