- NumberPlace (another name is Sudoku) is played on a grid of 9 x 9 spaces. Within the rows and columns are 9 “squares” (made up of 3 x 3 spaces). Each row, column and square (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column or square
- In this version, there are 2 levels for players: easy and hard which depend on the number of spaces players have to fill in. Players can change the level in the menu option
- To support for players, when they put a wrong number in a cell, the color of that number will be changed into red color, at that time, players have to change to another number. Players also use Clear Conflicting Cells option in the menu to clear all conflicted cells in the grid.
Players will win the game when fill in all the space cells without violating the above rules.
