Here are some of the common strategies that you can use to solve Asterisk Sudoku puzzles:
X-Wing: This strategy involves finding two cells that can only be filled with two different numbers. If these two cells are in the same row or column, then the other cells in that row or column cannot be those two numbers.
Swordfish: This strategy is similar to the X-Wing, but it involves three cells instead of two.
Hidden Single: This strategy involves finding a cell that can only be filled with one number. This is usually done by looking for a cell that is only in one row or column with a certain number.
Naked Single: This strategy is similar to the Hidden Single, but the cell with the only possible number is not hidden.
