The purpose of the game is to manage constantly growing snake that consists of randomly numbered cells. While moving snake you can eat free numbered cells that appear on the game field. The value of eaten cell is added to the snake’s head cell value. When total sum gets equal to 10 head cell disappears reducing snake size and adding to the score.
However if you eat the wrong cell and total exceeds 10 the game is over. New cells are constantly generated and added to the snake’s tail.
