If you love Sudoku, you are going to love Suguru. The first rule to Suguru is that each irregular sub-grid must contain 1~n (The variable n is the largest number in one sub-grid.) without repetitions. The second rule to Suguru is that the anti-king rule (Two identical numbers must not be orthogonally adjacent or diagonally adjacent.) must be followed [A king moves one space orthogonally (wazir) or one space diagonally (ferz).].
You can use the complete Sudoku/Suguru puzzles as Tic-tac-toe boards by adding the elements of luck. The conditions of each Tic-tac-toe board are to have 2~10 different numbers and to have at least two of same number. In the luck version of Tic-tac-toe, each number on each space is according to the number from the die or from the card (You place a piece according to the number that your rolled or drew); there are some outcomes (from dice or from cards) that a player gets a pro-wild (placing a piece onto any vacant space) or an anti-wild (removing an opponent's uncrowned piece from the board), and there are some outcomes (from dice or from cards) that a player gets no piece on the board (Usually, if a player rolls/draws a number that is not available on the board by total occupation, a player gets no piece on the board.).
Enjoy Suguru like enjoying Sudoku!
