Gameplay
Introduction to Farkle
If you have never played Farkle, or you need to be refreshed on the basic gameplay, please check out this article on Wikipedia. I figure that is a better plan than me paraphrasing what has already been well documented.
Getting to Know the Game Interface
Even if you are familiar with Farkle, it may not be obvious how certain elements of the game have been implemented. To address this issue, the game interface includes a "Quick Help" button. Click it and detailed tooltips are provided for most elements by hovering over the element.
