Slot Summary

Land at least 6 Ruby symbols and 6 Rubies of Tribute shifts from its 25-payline base game into a collection round with locked values and resetting respins. Old Skool Studios gives those Rubies the central role, while Free Spins provide a second route through a Mega Symbol arrangement. The 96.2% RTP, medium volatility and x2400.00 maximum place the emphasis on developing one feature state rather than constant base-game changes.

How It Plays

Ordinary wins use 25 fixed paylines across the 5x3 layout. Wild and Scatter symbols support that line game, but Ruby symbols provide the clearest route away from standard spins.

Once enough Rubies appear, the qualifying symbols stay in place while Respins continue. Every additional Ruby can refresh the remaining attempts and increase the collected total.

Theme & Atmosphere

Ancient and Aztec references frame the game as a search for tribute, with Gems serving as both the title subject and the principal feature currency.

Jungle growth and carved animal imagery reinforce the ceremonial setting, but the Ruby symbols remain the main visual guide because they identify meaningful collection events.

Features & Win Potential

Hold and Win converts the grid into a locked-symbol collection game. New Ruby arrivals preserve their values and reset the available Respins, allowing the occupied area to expand.

Free Spins use a Mega Symbol across the central reels, separating that round from Link Win play. Wild and Scatter symbols retain their familiar supporting roles.

Bonus & Free Spins

The Ruby bonus begins with at least 6 qualifying symbols and 3 Respins. Each new Ruby locks, adds its displayed value and resets the counter to 3.

Free Spins follow a separate Scatter trigger. During that round, the middle reels form a large Mega Symbol area, and additional Scatters can award more spins.

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 (96.20%), with wins capped at its top multiplier (2,400×).

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.
