Hot Rocks Game Mechanics
The game starts as a 5×6 reel set up game grid, and symbols can pay anywhere on the reels. The Hot Rocks slot triggers wins via a Scatter Pays mechanic where 8 or more of the same symbol will trigger a win, followed by a tumble of new symbols.
Above the game grid is the “Multiplier Reel” with 15 positions that will award multipliers and bonuses. The 1st position on the left is the active spot, and with each new spin a random position is selected, so you might need to get a few tumbles before you can achieve a multiplier, or you could start at the 10x position.
Hot Rocks Slot Symbols
The symbols in play while spinning the Hot Rocks slot are gem themed and feature a mix of smaller rocks and larger gems;
- Low-Paying Symbols: Brown, Green, Purple, Blue, and Red Rocks.
- High-Paying Symbols: Green, Purple, Blue and Red Gems.
Here’s a breakdown of the payouts for a $1 stake:

Hot Rocks Slot Bonus Features
Now we’ve gone over the basics of the gameplay at the core of Hot Rocks, it’s time to delve a little deeper and explore the different features and bonus games.
Hot Rocks: Multiplier Reel
You’ll notice that on the Multiplier Reel that you can progress through as you unlock tumbles of symbols some multipliers are surrounded by a Golden glowing hue. If you reach this point on the Multiplier Reel, you’ll receive one of four bonuses:
- Boost: Moves the reel a random number of positions from right to left.
- Symbol Blast: Removes a random number of symbols then new symbols cascade in.
- Add Wilds: Adds a random number of wilds to the reels.
- Multiply: Multiplies all the current multipliers by a random amount of either: x2, x3, x4, x5, x6, x8, or x10.
This bonus is randomly selected by a wheel that pops up and spins. Wherever it lands is the bonus you’ll recieve.
Hot Rocks: Free Games Bonus
Landing 4, 5 or 6 Scatter symbols anywhere on your reels will award 8, 10, or 12 free games.
The more Scatters you land the higher chance you have that you’ll start the Free Games with a higher multiplier and more bonuses.
During the Free Games bonuses all multipliers will be progressive and save the spot on the Multiplier Reel. Which can result in some massive wins near the end of the bonus if you manage to get plenty of tumbles and bonuses.
It’s also possible to re-trigger the Free Games, with 4, 5, 6, 7, 8, 9 and more Scatter symbols awarding an extra 5, 6, 7, 8, 9 and 10 Free Games.
Hot Rocks Slot RTP, Volatility, and Payouts
The theoretical return to player (RTP) for this game is 96.65%, however the returns vary slightly if you use the Feature Buys;
| Feature | RTP | Volatility |

| Enhancer 2 | 96.50% | High |
| Bonus Buy 1 | 96.69% | High |
| Bonus Buy 2 | 96.57% | High |

As a highly volatile slot, Hot Rocks offers the potential for large wins, albeit less frequently than lower-volatility games. In the base game, the maximum win is capped at 25,000x, but activating any Feature Buy unlocks the “Double Max” feature, boosting the maximum win potential to an impressive 50,000x.

The Free Games bonus is where the biggest wins can be found, thanks to the sticky Multiplier Reel, which continues to grow throughout your spins.
