This system reproduces the diversion "snake".
A series of characters proceeds onward the screen by keys squeezed by client. In the event that it touches itself or screen limit, the project ends. At the point when the snake moves, in subjective screen positions some digit (1-9) shows up.
The goal of the amusement is to make the snake eat the said digit, with the goal that it is added to the score. At the point when a digit is eaten, the span of the snake increments by the quantity of characters equivalent to the estimation of the digit.
In this adaptation of the amusement there are procurements for sparing/stacking as well.
