We do not name a test lab for this title, because no source publishes one. Pragmatic Play holds licences with regulators including the UK Gambling Commission as a studio, and that is what we state. We do not call the game "provably fair," because it is an RNG slot and that phrase does not apply. We do not cite a record win, because none is verified. And we do not claim the game is live in any specific casino unless the operator confirms it.
How we test games: we play the free demo, log the mechanics spin by spin, and rely on published Pragmatic Play figures rather than marketing claims.
We play the demo, then check every claim against the specs
Our process starts with the free demo and ends with the published numbers. We load Gates of Hades on virtual credits, run it for hundreds of spins, log what the mechanics do, and only then match our notes against Pragmatic Play's official specifications. Marketing copy doesn't set a score. In one 200-spin demo run we counted the dry stretches, timed how often clusters landed, and watched the wild multiplier meters stack and clear before writing a word of the review.
The demo runs the same maths as real play, which is why it is the right place to test. It gives us a play balance, around $1,000 in our sessions, and it lets us buy the feature to see the Free Spins without staking money. What it cannot do is confirm real-money payouts, so we never present a demo result as evidence of a cash win.
The steps we run for every review
Each stage produces notes we keep, so the review reflects what we saw rather than what a press release promised.
Load the demo
We open the free demo, confirm the bet range, and note the starting balance. For Gates of Hades that meant bets from $0.20 upward and a virtual bankroll to burn through.
Log spin by spin
We record how clusters form, when tumbles chain, how the per-column multiplier meter sums and clears, and how often wins land. Our hit-rate feel matched the reported figure of roughly one win every 3.45 spins.
Trigger the features
We chase 3-plus scatters for regular Free Spins and 6-plus for Super Free Spins, and we buy both, at 100x and 500x the bet, to see them on demand. We watch whether the multipliers really persist through the feature.
Verify against the specs
We cross-check our notes against Pragmatic Play's published RTP, volatility, and max-win figures, and against at least three independent reviews before setting anything in print.
Write and re-check
A second read flags anything unsourced, any figure we cannot attribute, and any claim that overstates what the demo actually showed.
Published specs beat marketing copy
When a studio's press blurb and its game sheet disagree, we follow the game sheet. Pragmatic Play describes Gates of Hades in glowing terms, but the numbers we quote come from the specifications, not the adjectives. The clearest example is the RTP: one default model and two lower ones an operator can deploy instead.
| RTP model | 96.52% default |
|---|---|
| Reduced model | 95.47% |
| Lowest model | 94.47% |
| Volatility | Medium (3/5) |
| Max win | 10,000x the bet |
We always publish the RTP spread rather than a single number, because the version a player actually gets depends on the casino, and that is the biggest hidden variable in the game.
How we set a rating
A score reflects design, mechanics, value, and how the game holds up over a long session, weighed against its own genre. Gates of Hades is a medium volatility cluster slot, so we judge it as one, not against a low-variance grinder. Presentation and the multiplier meter earn it credit. The familiar Olympus-adjacent formula and the punishing dry runs pull it back. That is how we arrived at 7.3 out of 10, close to the 6.7 to 7.4 range other reviewers reported.
A single demo session never sets a number on its own. Variance is too wide for that. We run enough spins to see the pattern, then anchor the score to the confirmed specs.
What we do not claim
Sources
Our specifications trace to the official Pragmatic Play game page and the studio's Pragmatic Play press release for the release date and max win. Licensing sits with the UK Gambling Commission. Reported figures such as hit frequency and max-win odds come from independent slot aggregators, and we flag them as reported, not official.
