The 8-puzzle problem involves a 3x3 grid with 8 numbered tiles and 1 blank space that can be moved. The simple explanation is that exactly half the configurations aren't possible to reach from any chosen starting point (or alternately, can't reach any randomly chosen ending point), so we divide total configurations (9!) by 2 to get the total number of states that can move step by step to the solution.
