Slot Summary

Between a conventional 50-line slot and a dedicated jackpot game sits Fu Double Luck Diamond Explosion, a RubyPlay release with two distinct feature routes. Explosion Free Spins hold and combine adjacent prize symbols into larger blocks, while Jackpot Pick Deluxe turns a Wild into a separate selection round. Free Spins add another route by converting a randomly chosen reel into Wild and prize symbols.

How It Plays

The base game runs on 50 paylines, so regular results follow a familiar line-pay structure before either of the game’s more specialized bonus routes appears.

Wilds substitute in ordinary combinations and can also open Jackpot Pick Deluxe. Scatter symbols instead provide access to Free Spins, keeping the two triggers separate.

Theme & Atmosphere

Lucky and Party themes frame the game through Chinese fortune imagery rather than a plain diamond presentation. The tone centers on celebration, luck, and prize reveals.

The diamond explosion idea is expressed mechanically as well as visually, since neighboring prize symbols join into larger shapes during the dedicated feature.

Party Lucky

Features & Win Potential

The fixed jackpots belong to Jackpot Pick Deluxe, where the player reveals concealed outcomes until a jackpot result is established. Multipliers can increase that result.

Explosion Free Spins use held prize symbols and block formation. As adjacent prizes join, the available reward is determined by the resulting block rather than a standard payline.

Free Spins Multiplier Scatter Symbol Wild Symbol 5 Reels Bonus Game BonusGame: Pick Objects Free Spins Multiplier Fixed Jackpots

Bonus & Free Spins

Landing 3 Scatter symbols awards 8 Free Spins. At the start of each spin, one reel is selected and filled with Wild and prize symbols.

The Explosion feature begins with 5 rounds after at least 6 prize symbols appear. Held prizes combine with adjacent prizes, and filling the available positions ends the sequence.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (96.33%), with wins capped at its top multiplier (800×).

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.
