Fairness & RNG

Our Commitment to Fair Play

At SpinArc, fair play is not a policy document — it is the technical foundation on which every game is built. Every game outcome on our platform is determined by certified Random Number Generator (RNG) software, ensuring that all results are genuinely random, unbiased, and independent of previous rounds.

What Is an RNG?

A Random Number Generator is a computational algorithm that produces sequences of numbers with no discernible pattern. In casino gaming, RNG software determines the outcome of every spin, card deal, or dice roll. Because each result is statistically independent of all previous results, no strategy, timing technique, or pattern recognition can influence outcomes.

Independent Auditing

Our RNG systems and game mathematics are tested and certified by independent testing laboratories before any game is made available on the platform. These audits verify:

• That the RNG algorithm produces statistically random outputs.
• That published Return-to-Player (RTP) percentages accurately reflect actual game mathematics.
• That no player, operator, or third party can manipulate game outcomes.
• That game software performs exactly as described in the game rules.

Return to Player (RTP)

RTP is a percentage that indicates the theoretical long-term payout of a game relative to total bets placed. For example, a slot with a 96% RTP will, over millions of spins, return an average of €96 for every €100 wagered. RTP is calculated over a very large number of rounds and does not predict any individual session’s outcome.

RTP information for each game is available in the individual game rules or paytable, accessible directly from the game screen.

Provably Fair Games

Select games on the SpinArc platform use provably fair technology, allowing players to independently verify game outcomes after each round using cryptographic hash functions. Instructions for verification are provided within the relevant game interface.

Software Providers

All games on SpinArc are sourced from licensed, reputable software providers whose products are independently certified. Provider certifications are renewed on a regular basis and are subject to ongoing compliance monitoring.
