In the jungle, snakes are growing in length, or they are slithering in any possible direction. In a normal life, snakes live alone but they feel happy in this way until they are touched by other snakes. If an un-welcome touch happens, it is lethal. Sound scary, right?
When a player runs out of the 7 tiles in his supply, the goal of the game is achieved. It tells us that his snake(s) survive and survive well in the jungle. Therefore, he is the winner of the game.
