FAQ

Common questions, real answers

How do you rate game providers?

We score every provider across 12 criteria including library size, average RTP, volatility variety, bonus mechanics, mobile performance, regulatory standing and historical payout reliability. Scores update quarterly.

Are these reviews independent?

Yes. We may earn affiliate commissions on casinos linked from our reviews, but provider and slot scores are never influenced by commercial agreements. We disclose every affiliate relationship.

Is the RTP listed here the real RTP at every casino?

Not always. Some providers (including NetEnt, Play'n GO and Pragmatic) ship multiple RTP versions of the same slot. We list the highest published RTP and flag whenever a casino runs a lower variant.

Can I play any of these games for free?

Almost all provider review pages include a free demo embed (no deposit required). Demos are not available for jackpot games due to provider licensing rules.
