I just played a couple roblox games. One money incremental [event] was based on increasingly microscopic rng like 1/2,1/50,1/250... as items that you try and get using upgrades to luck #, bulk roll #, clone reward #. they also operated like milestones in that in addition to currency multipliers they might also have surprising boosts to make you go for them and try to game the system, picking from several different possible rng rolls to improve in that way. There was also circle grinding incremental which ended up mostly featuring a mining feature, which is a minecraft like cave with unbreakable walls of blocks that respawn a ore randomly a delay after mining one. this one from the outset promised you could get a million times stronger then initially because it was one part of a network of interconnected upgrade areas, and questions of how to handle it were a bit more involved then usual because of that when do I leave questioning. It played out with an upgrade that has a small chance to deal a click to an whole layer (around 100x) after mining a block, although each new cave in the sequence of deeper caves would start off taking around 10+ clicks per block or more by rarity. Recalling times of recording myself playing something my experience learning these was probably more nuanced than I may give credit. I also played prestige Trees but didn't get far enough, may pay more attention now,
