RTP: 0.96%

We haven't been able to confirm a reliable RTP figure for Heartburst 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

Not Confirmed volatility means Heartburst isn't going to drain your credits in twenty cold spins, but it's also not going to hand you the undisclosedx ceiling on a Tuesday afternoon. The N/A hit frequency and 0.96% RTP work together in a math model that's designed for sustained play rather than one-shot swings.

Hit Frequency: N/A

We don't have a confirmed hit frequency figure for Heartburst 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 Eyecon calibrated the maths. We'll update this with a precise figure when it becomes available.

Stake Range: $0.01 to $50

The minimum stake on Heartburst drops below $0.10, which makes this accessible to players at nearly any bankroll level. At not confirmed volatility, the low floor matters — you can run 50–100 test spins at minimum stake without significant exposure. The undisclosedx ceiling scales with bet size, so higher-stakes play is available up to $50.00 for players who want more skin in the game.

Who Should Play Heartburst

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 Heartburst 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

On the numbers, Heartburst is solid. 0.96% RTP is at or above the benchmark, not confirmed variance is manageable for most player budgets, and the undisclosedx ceiling gives the features a meaningful upside. Eyecon built something competent here rather than something headline-grabbing. That's not a criticism — competent math is underrated.
