Slot scores are calculated across five criteria. Each criterion is weighted by how much it actually impacts a player's experience and long-term value.
We verify the published RTP against provider documentation. Slots below 95% RTP are not recommended. The math model — how the RTP is distributed between base game and bonus — is also assessed.
How the bonus round works, how often it triggers, and whether the mechanics are interesting or repetitive. A well-designed bonus that rewards skill or understanding scores higher than a pure coin flip.
The advertised max win is noted, but we also assess whether it's realistically achievable given the volatility and bonus structure, or whether it exists only as a theoretical maximum.
How the slot actually plays across a real session — not just its stated volatility label. Some slots labelled "high volatility" play far more medium in practice. We report what we actually experience.
Theme, sound design, animations, and whether the slot is genuinely engaging to play over multiple sessions or becomes repetitive quickly. Subjective, but honest.
We do not give every slot a 9 or 10. If a slot doesn't deserve a high score, it won't receive one — regardless of who made it or whether we have an affiliate relationship with the casino where it's played.
Casino scores are based on six criteria assessed through real deposits, real withdrawals, and real gameplay at each platform.
A casino must hold a valid licence from a recognised regulator — Curaçao, Malta (MGA), UKGC, or equivalent — to be listed on SlotArk. We check licence status before publishing any review and revisit it periodically. Unlicensed casinos are not reviewed regardless of their bonus offers.
Bonus wagering requirements, game contribution rules, maximum bet limits during wagering, and time restrictions are all reviewed in detail. A 200% bonus with a 60x wagering requirement scores lower than a 100% bonus with a 30x requirement.
The number of providers, availability of high-RTP slots, and whether the casino offers the specific games we review on SlotArk. We also check for RTP setting transparency — some casinos run reduced-RTP versions of popular slots.
We test actual withdrawals where possible. Casinos that process crypto withdrawals within an hour score higher than those that take 3–5 business days. Unreasonable withdrawal limits or excessive verification requirements are noted.
Live chat responsiveness, mobile usability, and how the casino handles complaints. We check community forums and player reports alongside our own testing.
All slot reviews are based on live sessions streamed on Twitch and Kick. This means our testing is publicly verifiable — the sessions exist on VOD. We don't claim to have tested a game we haven't played.
Casino reviews are based on active accounts held at each platform. We do not review casinos from their registration page alone — we test the full experience from deposit to withdrawal.
SlotArk earns income through affiliate commissions. This creates a potential conflict of interest which we manage through a strict editorial policy:
