Are there games similar to Borderlands Science?

I’m hoping to find a game similar to Borderlands Science. Preferably something that can be played on a phone. Top tier would be the ability to play offline (sometimes I don’t have great cell service though I understand it would need to be connected to some degree).

I can easily zone out on somewhat mindless games and play for hours if I have the free time or spare attention. Progress tends to be my limiting factor. If I’ve just put 10 hours into a game and the next time I pick it up is the exact same as the first it can feel like a waste. If instead, those mindless hours were going to a good cause that is progressing (even if I don’t directly see that progress), it might make it easier. Plus it’s going to a good cause.
