Slot Summary

Three symbols across the central row are enough to shift Coin Up: Hot Fire from its compact base game into a Hold and Win sequence. The three-reel format from 3 Oaks uses Sticky Coins to preserve trigger progress, then adds Coin Up and Multi Up modifiers from an extra row. One raises held values or changes coins, while the other places Multipliers onto positions below. The maximum win is 500x.

How It Plays

The base game uses three reels, three rows and one payline, keeping ordinary results brief. Attention stays on the central row because three qualifying symbols there open the feature.

A Sticky Coin can remain on the grid while later spins search for the remaining trigger symbols. This persistence turns several base turns into one developing feature attempt.

Theme & Atmosphere

Fire supplies the heat motif, while Treasure appears through coins and four fixed prize levels. The compact layout resembles a small cash machine rather than a story-led adventure.

The extra modifier row keeps the Treasure subject readable by showing changes above the coins they affect. Fire serves mainly as a visual marker for boosted values and feature entry.

Features & Win Potential

Hold and Win begins with three Respins. Bonus symbols lock when they land, every new symbol resets the counter, and Cash Collector outcomes gather the values already displayed.

Mystery symbols can reveal values or Fixed Jackpots. Filling all nine positions awards the 500x top prize, while partial grids settle according to their collected symbols.

Coin Up increases values or changes Sticky Coins into Mystery symbols. Multi Up adds a Multiplier to the position below, so the extra row modifies the held grid directly.

Bonus & Free Spins

Three qualifying symbols on the central row trigger the Bonus Game. During its three Respins, landed Bonus symbols remain fixed and every new arrival restores the counter.

The Ultra Bonus Game uses the same holding structure but introduces Bonus symbols with higher values. It can also be reached by filling the dedicated meter.

Bonus Buy prices the regular feature at 40x the stake and the Ultra version at 75x. The purchase changes entry only, leaving the collection rules intact.

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 (95.75%), with wins capped at its top multiplier (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.
