Slot Summary

A fixed-payline format gives Locked Hearts 40 a conventional starting point, but its high volatility and x4000 win ceiling shift the emphasis toward less frequent feature-driven results. Fazi Interactive separates the main routes clearly: expanding wilds support ordinary spins, while free spins turn those wilds sticky and preserve them for the remaining round.

How It Plays

Results are evaluated across 40 fixed paylines, with wild symbols helping form combinations during the base game. The separate scatter symbol controls entry to free spins.

A risk game provides an optional route after qualifying wins, while the main feature path depends on collecting the required Locket Heart Scatter symbols.

Theme & Atmosphere

Love and Romance define the presentation through heart and locket imagery, giving the game a sentimental subject without changing its traditional fixed-payline structure.

The Fantasy element appears through the lock-and-release idea: ordinary heart wilds become persistent symbols once the free-spins feature has opened.

Fantasy Love Romance

Features & Win Potential

Expanding Symbols and Wild Symbols work together on the middle reels, where a Heart Wild can extend across every visible position on its reel.

Sticky Wilds matter specifically during free spins. Once an expanding wild lands there, it remains available for every spin left in that round.

Bonus & Free Spins

Locket Heart Scatter symbols trigger free spins. During the feature, Heart Wilds on the middle reels expand fully and stay locked until the round ends.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.57%), with wins capped at its top multiplier (4,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
