Welcome to "Number Grid Challenge", an exciting game that will test your ability to arrange numbers in ascending order to complete rows and columns! Objective of the game: Your goal in "Number Grid" is to fill the 3x3 or 4x4 grid with the random generated numbers between 1 and 999 in order to get rows and columns sorted in ascending order, always starting from left to right. How to play: - Game Grid: The game is played on a 3x3 (or 4x4) grid, for a total of 9 squares. Each box can contain a number between 1 and 999. - Random Numbers: On each turn, you will be randomly assigned a number between 1 and 999. Your task will be to place this number in one of the empty squares of the grid. - Sort Ascending: Whenever you enter a number, make sure the row and column where you placed the number are sorted in ascending order from left to right. - Strategy and attention: Use your cunning and carefully plan your movements. As you go, things may get complicated, and you'll need to be careful not to get stuck with numbers that don't fit into the required ordering. - Victory: To win the game, complete the grid so that all rows and columns are sorted in ascending order. - Challenge yourself and others: Try to improve your score every time you play, trying to complete the grid in as few moves as possible.
