Slot Summary

Following Gamzix's Only Coins line, Only Diamonds revisits the same feature-first idea with gems replacing an ordinary paytable. The base game has no regular paying combinations, so its purpose is to open a Hold and Win round where Diamond values, Cash Collector actions, additive upgrades, Mystery Symbols, and Fixed Jackpots determine the award. Medium volatility and a 3500x ceiling give this sequel a measured profile despite concentrating every payout inside the bonus.

How It Plays

The base spin does not pay ordinary symbol combinations. Instead, the active row is used to assemble the symbols needed to enter the game's single award-bearing phase.

After the trigger, qualifying Diamond and special symbols occupy the variable-height reel area. The round continues through Respins until the counter expires or every position is filled.

Theme & Atmosphere

Gems are the entire subject rather than one premium symbol among many. Every potential award, modifier, and jackpot is represented through the Diamond system.

That narrow visual premise matches the unusual pay structure. With no ordinary line symbols competing for attention, the presentation keeps focus on collected values and special gem outcomes.

Gems

Features & Win Potential

Cash Collector symbols gather displayed Diamond values. Additive symbols increase existing prizes, while Mystery Symbols can reveal prize values or Fixed Jackpot outcomes.

The interaction among Cash Collector, Additive symbol, and Mystery Win Bonus Spin effects gives the feature its variation without restoring conventional line wins.

Bonus & Free Spins

The Hold and Win Bonus Game starts with three Respins. Each new qualifying symbol becomes sticky and resets the counter, extending the round until no spins remain or the grid fills.

Fixed Jackpots sit inside the same collection round. Filling all available positions awards the Grand jackpot, while other jackpot symbols can contribute smaller fixed prizes.

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 (96.01%), with wins capped at its top multiplier (3,500×).

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.
