Nudoku+ is a Sudoku game with a number of display variants to choose from:
- A selection of standard Emojis
- A Set of hand painted drawings
- A Collection of AI-generated images
- 9 different colors
- The usual digits 1-9
Like a normal Sudoku, to complete the Puzzle you have to fill in all the cells so that no row, column or block of 9 cells contains the same item twice. When you start a new game, some cells are already filled in such a way that there is only one single solution to achieve this. The hint button will show you if there is a cell filled with a wrong item, or, if all are correct, will show you one additional cell filled.
There is a mode to freely fill the empty board. In this case, after each move the board is checked if a solution is still possible. In some cases where there is no solution left, the calculation may take a minute, more or less. A red frame means no solution left, A green frame indicates that a single solution was found. Pressing the play game button then starts the game timer for the "Custom" High Score category,
