Sudoku Nejiru is Sudoku with a twist...
Sudoku Nejiru looks like a normal Sudoku 9x9 board, but it has two new controls that other boards do not have.
Spin left, and spin right.
Each of the 9 regions of the board are randomly oriented at the start of each game. In addition to following the normal rules for Sudoku, the regions must also be correctly oriented to complete the game.
