Do you mean you are having technical problems getting the game to run or you don't know how to play snake?
If it is technical problems you will have to wait for dev to answer but if just don't know how to play then it is quite easy. You are a snake that grows when it eats Ucoins. Eat as many Ucoins as you can without running into your tail or a wall.
not technical problems, I thought it was odd as the usual game of snake you would be moving and would then collect the other parts of the snake, on my S3 the blue dot just remains in the centre and does not move although I can see the Ucoins, the main blue snake is not moving, am I going mad or is this a tech issue do you think?
