Slot Summary

A royal griffin guarding northern kingdoms gives Royal Griffin its central figure, while RubyPlay turns the defense of Treasure into a sequence of prize-symbol Respins and upgraded Free Spins. The game begins with 30 paylines, then changes to 243 ways during its Free Spins modes. Its 96.47% RTP, medium volatility, and x2300.00 maximum win frame a measured math profile, but the defining decision is which bonus tier the triggering symbols produce.

How It Plays

Ordinary spins use 30 paylines, with Wild Symbol and Scatter Symbol support alongside Prize symbols. Landing enough Prize symbols moves play into a Respin format.

The bonus modes alter the win evaluation rather than merely adding unpaid copies of the base spin. Free Spins change the active structure from lines to 243 ways.

Theme & Atmosphere

A griffin guard connects the Fantasy, Mythology, and Royal themes, while Knights and Warrior imagery cast the creature as a protector rather than a roaming monster.

Medieval halls, Crown symbols, and guarded Treasure give the setting a defensive purpose. The royal premise therefore matches the collection of protected Prize symbols in the feature.

Features & Win Potential

The Hold and Win feature begins when six or more Prize symbols land. Those symbols enter a Respin sequence where further prizes can occupy the remaining positions.

A Super Prize symbol upgrades the Respin mode, while Expanding Symbols appear in the enhanced Free Spins version. Each upgrade changes feature behavior rather than only increasing presentation intensity.

Free Spins Scatter Symbol Wild Symbol Medium volatility 5 Reels Additional Free Spins Expanding Symbols 96% RTP Bonus symbols Hold and Win 30 Paylines

Bonus & Free Spins

Free Spins replace the normal 30 paylines with 243 ways to win. The enhanced version retains that format and adds expanding Wild Symbol behavior.

Additional Free Spins provide more evaluations under the altered ways format, separating the round mechanically from the line-based base game and the Hold and Win Respins.

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 (96.47%), with wins capped at its top multiplier (2,300×).

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.
