This is my 6th Sudoku contribution to:
Daily League! The League of Extraordinary Ladies and Gentlemen
Rules:Place numbers in the grid such that each row,column and 3*3 box contain the numbers 1-9. Additionally, some cells will have circles inside and some others will have squares. Cells with circles must contain the digits 1,2 and 3. Cells with squares must contain the 4,5 and 6. Blank cells must contain the digits 7,8 and 9.
Difficulty: Hard (Not literally hard, But hard considering the difficulty of usual TRIO Sudoku)
