Thanks for the playing and I appreciate any and all feedback.
I've not played the other game for years or possibly decades so the game is based mainly on my memory and test playing.
I did a quick look online for percentages where I happened to see that it probably started with a clear first shot so quickly put a button option in. I didnt go as far as to see if it should be a 0 or not (though did wonder) which may have taken a little bit more of a effort to implement!
And with Reset and Undo options I thought that covered things enough to be playable.
I see I'm still top of one high score table! For now.... I like a challenge ;-)
