Are there more rules than are described in the “rules” and “scoring” sections? I haven’t played Farkle. I think the dice are greying out because they’ve been scored? After that, I think the grayed-out ones aren’t used for scoring (e.g. you can’t get doubles with a grayed-out and not-greyed-out dice)? Does the round number have any purpose? Is there any reason not to bank?
I’m afraid I'm not really the target market for this kind of game (chance-heavy + strategy-light) so it’s for me hard to comment much on the gameplay. I’m sure I'm missing something in the rules too. It was interesting to try something so far outside my usual interests though. Maybe with some flashing and shaking and particles and animations, it could have a skinner-box kind of appeal?
The layout feels well-thought-out for playing on a phone.
