Hey Product Hunt! 👋
I'm Maj, a casino analyst from Slovenia. I run Balkasino — a casino review site covering 10 Balkan markets in 11 languages.
I built Make-A-Slot because I kept getting asked "how does a slot machine actually work?" by readers who didn't trust the math explanations. So instead of explaining it, I let them feel it.
You can configure every variable that casinos actually tune: reel count, rows, paylines, RTP (the percentage the house keeps), volatility, free spin triggers, and bonus buy cost. Then spin it. Watch 96% RTP actually mean you lose €4 per €100 over time. Or crank volatility to "very high" and see 200 spins of nothing followed by a 500× hit.
It's a teaching tool disguised as a toy.
Built with React on an Astro static site. The RNG and payout engine are fully client-side — no server calls, no tracking, just math.
Happy to answer anything about the probability model, the gamification layer (there's an RPG system hiding in there), or the Balkan iGaming market 🎰
