I keep coming back to this, such a simple idea yet compelling because each run builds in complexity. Yes, it's actually a deckbuilder but it still relies more heavily on luck of the draw than anything else. If slot machines really were this complex they'd be much more addicting. I love how adjustable the base colors are, a really appreciated detail for visual impairment that has allowed me to play longer than I would have. Love obliterating landlords too.

Edit: Still obsessed with this and the more I play it the more I like it. I'm up to building 16 and still discovering new items and strategies. When you get a powerful run it's nearly as thrilling as winning real money. Bumping up my score because this is really a perfect little gem that rewards exploration and experimentation much more than you suspect it will.
Just to be goofy I recently tried an eggs-and-pearls-focused run that ended up being my best run ever after I landed the diver, frying pan, essence frying pan, chef, and two golden arrows. I sometimes had omelettes paying off at 120+ per spin, absolutely nuts.
