How the Game Plays

Cave Of Gems transports you into a glowing subterranean cavern where a friendly goblin assists in unearthing valuable treasures. Developed by BF Games, this slot utilizes a standard 5x3 grid with 30 fixed paylines that reward combinations from left to right. The screen is filled with vibrant gemstones, bubbling potions, and mining gear, creating a polished fantasy aesthetic. Winning sequences are formed by matching colored gems or stylized card suit symbols, while the goblin character acts as a central figure in the game’s unique collection mechanics.

Free Spins Explained

The free games round is triggered by landing three or more Treasure Chest scatter symbols anywhere on the reels, awarding up to 20 spins. During this feature, a Grand Nitro Meter appears to track progress. The round can be retriggered by landing just two or more scatters, providing additional spins to extend the bonus.

Nitro Counter & Persistent Wilds Explained

Nitro symbols can appear on the reels with values of 1, 2, or 3, which are then added to individual counters located above each reel. Once a counter reaches three, the corresponding reel transforms into a Persistent Wild for the next three spins. A notable mechanic resets all active Persistent Wild timers back to three if a new one is triggered. If you manage to turn all five reels into Persistent Wilds simultaneously, a special prize of 200x the bet is awarded.

Grand Nitro Meter & Rewards Explained

During the free games, the Grand Nitro Meter collects all Nitro symbols that land. Reaching 15 on the meter awards the Grand Reward of 500x the bet. Additionally, a random Explode Feature can trigger if the meter is at least three, placing a number of bomb wild symbols onto the grid equal to the current meter value before resetting it to zero.
