In this case, it looks like the Gemini output that you linked — as you mentioned — doesn't include the requirement for a scrambler/solver/timer, so it's hard for me to comment directly on the comparison.
I ask because we can totally add Gemini 2.5 pro as one of the models we use under the hood!
Well, I was not comparing but it was just an observation.
I understand Magic has more constraints on which libraries it can use and probably is for forms-flow kind of workflows and not for managing complex states of games.
While we certainly do constraint it, it still should be able to manage creating a Rubik cube solver (even though that is definitely not the intended use case).
There's a lot of "AI tourism" in the space and so never want to constraint it too much + random use cases like this always excite us: https://news.ycombinator.com/item?id=43752176#43752637
I created a basic flight simulator a while back in Magic Patterns in 3 prompts: https://www.magicpatterns.com/c/xensje9nkf48syshrkcmsc
Your Rubik's cube prompt I'm going to add to our eval set :)
