Serpent game on a mobile application is a classic arcade-style game where the player controls a snake and tries to eat as much food as possible while avoiding obstacles and the snake's own tail.

In the game, the snake moves around the screen, and the player must guide it towards the food. As the snake eats more and more food, it grows longer and becomes more difficult to control. The game ends when the snake crashes into a wall or its own tail.

The player can control the snake's movement by swiping in the direction they want it to go. The game is played on a 2D grid, with the snake and food appearing as simple graphics.

The mobile application version of the game may have different features such as multiple levels, power-ups, different game modes, and social sharing options. The player's scores may also be saved, allowing them to compete with friends and other players for the highest score.
