RTP: 0.96%

We haven't been able to confirm a reliable RTP figure for Diamond Vapor at the time of this review. That's not unusual for newer releases where the provider hasn't published full specs yet, but it does mean you're playing with one less data point than you'd have on a well-documented game. We'll update this section when verified data becomes available.

Volatility: Not Confirmed

Medium volatility is the balanced choice, and Diamond Vapor fits the profile correctly. You'll see the reels pay at N/A — often enough to keep your balance from collapsing before the bonus round triggers. The undisclosedx ceiling isn't designed to make headlines, but it's real upside at a stake that works for a normal session length.

Hit Frequency: N/A

Hit frequency data for Diamond Vapor is unconfirmed. Not Confirmed volatility implies an infrequent-to-moderate win rate in the base game. Use the volatility rating above as your guide to session planning until a precise figure is published by the provider or verified by an independent lab.

Stake Range: $0.01 to $1

A $0.01 floor puts Diamond Vapor in the truly accessible range. For players who want to explore the maths of a not confirmed game without a meaningful bankroll commitment, that low entry point is genuinely useful. The $1.00 ceiling means there's room for proper stakes too, so this isn't just a low-limit game dressed up as something bigger.

Who Should Play Diamond Vapor

Play this if: You want to play at a stake level where the game can breathe without requiring a deep bankroll commitment. The balanced volatility and 0.96% RTP make Diamond Vapor mathematically reasonable for sessions of most lengths.

Skip this if: You need either very frequent wins to stay engaged or very high variance for the thrill. Not Confirmed volatility sits between both extremes by design — players who strongly prefer one end of the spectrum tend to find the middle unsatisfying. Know which type you are before loading this one up.

Verdict

Diamond Vapor is a balanced option from Endorphina: 0.96% RTP, not confirmed volatility, undisclosedx top prize. Nothing extreme in any direction. For players who want a game that works across different session lengths without demanding either a deep bankroll or a tolerance for pure variance, the profile fits. The demo is the fastest way to verify the feel matches the specs.
