Arrange the numbers in order by sliding tiles into the empty space. The classic sliding puzzle game challenges your spatial reasoning and planning skills.
Click on tiles adjacent to the empty space to move them. Your goal is to arrange the numbers in order from 1 to 8 (for a 3x3 puzzle), with the empty space in the bottom right corner. Complete the puzzle in as few moves as possible to maximize your score. Higher difficulty levels have larger grid sizes.
