RTP: 0.96%

When we last checked, we were not able to confirm the RTP for Cool Diamond II. RTP data matters because it sets the long-run cost of playing. Without a verified number, you're making a blind bet on the maths. Some games in this situation have operators withholding unflattering numbers. Others are simply underdocumented. Either way, it's worth factoring into how long you're willing to play without that information.

Volatility: Not Confirmed

Medium volatility is the balanced choice, and Cool Diamond II 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

We don't have a confirmed hit frequency figure for Cool Diamond II at time of publication. Given the not confirmed volatility classification, you can expect wins to land somewhere between 1 in 3 and 1 in 6 spins depending on how Amatic calibrated the maths. We'll update this with a precise figure when it becomes available.

Stake Range

Stake range data for Cool Diamond II is not confirmed at time of publication. We'll update this section with the verified minimum and maximum bet when the provider publishes full specs.

Who Should Play Cool Diamond II

Play this if: You want a game that won't drain your stack in twenty spins but still has real upside in the features. Not Confirmed volatility is the middle path — you get enough base game activity to stay engaged while retaining a undisclosedx ceiling that makes the bonus round worth chasing.

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

The 0.96% RTP and not confirmed volatility on Cool Diamond II make for a predictable profile in the best sense: you know roughly what kind of session you're buying. The undisclosedx max win is the aspirational number, the hit frequency determines how often you stay in contact with the features, and the RTP controls the long-run expected cost. All three are reasonable here.
