Jenga is a popular game of physical skill and balance. It consists of a tower made up of 54 wooden blocks stacked in a 3x3 grid, with each layer of blocks placed perpendicular to the one below it. Players take turns removing one block at a time from the tower and placing it on top, without causing the tower to collapse. The game ends when the tower falls, and the last person to successfully place a block without toppling the tower is the winner. It requires a steady hand, strategic thinking, and a bit of luck.
