Leo Vasquez audits casino game integrity, RNG certification and RTP disclosure. A former QA engineer at a slot studio, he understands how slot maths actually works — and which fairness claims hold up versus which are marketing.
About Leo
Leo Vasquez is BestBonus.co.nz's Game Auditor & Fairness Expert. Leo spent five years as a quality assurance engineer at a Tier-1 slot game studio, working directly on RTP validation, RNG certification submissions and integration with independent testing labs including eCOGRA, GLI, iTech Labs and BMM Testlabs. He moved to casino review work in 2022 with a clear thesis: most players have no idea what's actually being certified when a casino claims "RNG certified". Leo's reviews focus on whether testing-lab certification is real and current, whether RTP is publicly disclosed (and at what level — operator, game, or session), and which casinos support provably fair games (most don't). He covers game provider quality across NetEnt, Pragmatic Play, Evolution Gaming, Play'n GO, Hacksaw Gaming and 100+ studios, and is particularly critical of casinos that lower RTP on certain slots versus the provider default — a practice that's legal but rarely disclosed.
