Slot Summary

Released in 2026, Amazing Builder Prometheus turns symbol collection into preparation for a position-based Bonus Game. SpinPlay Games lets marked reel positions advance through several fire states before the completed arrangement pays, while random feature triggers, a pick round, and Free Spins provide separate outlets for the collected symbols. Its medium-volatility profile carries a 96.51% RTP and 5000x ceiling.

How It Plays

The base game pays from left to right across 20 fixed paylines. Alongside line wins, Wild, Bonus, and Builder symbols feed separate collection meters tied to feature access.

A qualifying spin can convert a filled meter into one random feature. This gives otherwise ordinary base play a second purpose, since collected symbols may activate the pick round, Free Spins, or the main Bonus Game.

Theme & Atmosphere

Mythology supplies Prometheus as the central figure, using his association with stolen fire to explain why reel positions pass through stronger fire states during the feature.

The Greek setting is functional rather than decorative. Temples, mountains, and the Titan's fire provide a clear visual language for collection, upgrading, and eventual release of stored values.

Mythology

Features & Win Potential

Symbol Collection tracks Wild, Bonus, and Builder arrivals, with Random bonus symbols capable of opening different features. The central Bonus Game then upgrades individual reel positions over time.

The Pick Objects round reveals matching Fixed Jackpots and can attach Multipliers to selected icons. Respins and Sticky Symbols give completed positions additional opportunities to affect the final result.

Bonus & Free Spins

The Free Spins feature begins with 10 spins after 3 Bonus symbols appear on the required reels. Each spin selects a reel to become an Expanding Wild reel.

The Pick Objects Bonus Game asks for 3 matching prize icons. MINI, MINOR, MAJOR, and MEGA Fixed Jackpots can appear, while icon Multipliers may increase the matched prize.

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 (96.51%), with wins capped at its top multiplier (5,000×).

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.
