    It'll always go to a tie-break because the chance of breaking serve on any given point is 1/3. So it's very unlikely you will break for four points in a game before the server has reached four points.

    You could instead say the first 'draw' of any given point takes it to 'second serve', and a draw on the second serve gives the point to the server. This increases the odds of breaking on any given point from 1/3 to 4/9, so should lead to more competitive games.

    And no, I don't know why I'm encouranging you Martin!

    You could but try it you'd be surprised that breaking serve can and does happen. (and now Im encouraging you back :) )

    RPS is NOT a game of chance, especially if you've played against that person before.
