About Sudoku Mega

In Sudoku Mega, you'll be faced with a 16x16 grid. Some of the grid squares already contain the answers. To complete the puzzle, fill in the empty squares of the grid with the digits 1 through 9 and letters A through G.

The puzzle is solved when each row, column, and house contains the digits 1 through 9 and letters A through G with each digit or letter only appearing once.
