Snake games primarily revolve around the player's control of a snake-like entity that grows in size as it consumes various items, typically depicted as food. The gameplay is straightforward yet addictive, appealing to players of all ages. The challenge lies in navigating the snake as it grows longer, avoiding collisions with walls or its own tail, which can result in losing the game. The simplicity of the controls, often just requiring directional inputs, makes it accessible while still allowing for intricate strategies as players aim for high scores.
