**ARITHMETIC BOX ( Rated - Hard)**
Place a number from the given set into each of the nine cells such that all six equations are satisfied. Equations are read left-to-right and top-to-bottom and follow BODMAS rule.

**DOORS ( Rated - Easy)**

Each cell represents a room. All rooms are connected (by a horizontal-vertical path) and they are separated by doors. Some doors are closed while some are open. The number in a cell indicates the amount of rooms visible from that cell (excluding the cell itself) in all four directions.

**NO TOUCH DIAGONAL SUDOKU (Rated - Medium)**

Place numbers 1~3 in the grid such that every row, column, 2x3 box and two diagonals contains each number exactly once. Same numbers cannot touch other diagonally.
