Ludo is a popular board game that originated in India, known as Pachisi. It is played by two to four players, each with four pieces that move around a square board based on the roll of a die. The objective is to be the first player to move all four pieces from the starting area to the home area. The game board features a cross and circle design, with each player's path marked in their color. Players take turns rolling the die, and they can move their pieces forward according to the number rolled. Landing on an opponent's piece sends it back to the starting area, adding a competitive element to the game.
