This seems like a pretty fun project. I'll probably end up using an open source solitaire variant, so it can look good. That is under the condition, though, that the rules of solitaire are the same, in that there are still the same suits and cards, just with custom text on them. Would you instead like to change the rules entirely? e.g. have one phrase only be able to be placed below two other phrases. Like an answer to a question, or something like that. If that's the case, I may have to build it from the ground up, which is definitely doable (and fun, I think), but it wouldn't have a very nice-looking interface, at least not in a short amount of time. I assume that wouldn't be a huge issue, since you said that this is only a proof of concept. You probably noticed that I bid lower than all the other current bids. There were two reasons I did this: 1) It seems like a fun project that shouldn't take too long, and 2) I have no experience with this website and no reviews on my profile, so I recognize choosing me may be a bit of a risk in that regard. I assure you that is well worth it.
