The Nim Game is a mathematical strategy game involving two players who take turns removing objects from distinct piles. Each player can remove any number of objects from a single pile during their turn. The objective is to be the player who removes the last object, thereby winning the game. The game can be played with any number of piles and objects, making it versatile. The winning strategy often involves understanding the concept of Nim-sum, which is the binary XOR of the pile sizes. Players can use this strategy to determine optimal moves and increase their chances of winning against their opponent.
