why do some slot developers make games that feel fair and others feel rigged.

Sometimes I’ll sit down at a slot and just get this gut feeling the game is actually giving me a shot. Good hit frequency, base game isn’t a dead zone, and when I lose it’s not in some sudden bottom-out streak. Other slots, I swear, I never see a feature trigger and it’s just dollar after dollar disappearing for 20 minutes straight. I’ve noticed some developers, over and over, put out games that lean way more “fair” or at least fun for longer. Others, especially the newer studios, seem like they crank up volatility but forget about actual gameplay.

Is this all just down to the math model and RTP they publish, or do some devs program these things to feel rigged even if the numbers say otherwise? Or am I just falling for confirmation bias and a cold streak makes me salty? Wondering if anyone else tracks their spins and notices any patterns between developers, or if it’s just random luck over time. Anybody dig into this or keep logs?
