RTP Cave of Gold is a five-reel slot from BF GAMES with 30 paylines and high volatility. The game follows Goblin through a cave setting, where players collect Nitro symbols, Treasure Chest Scatters, and Bomb Wilds. The stated RTP is 94.24%, with bet sizes ranging from 0.3 to 60.
The main mechanic is the Persistent Wild Feature. Single, Double, or Triple Nitro symbols build the Nitro Counter, and after three are collected, one reel becomes a Persistent Wild Reel for the next three spins. If all five reels trigger this feature at once, the result is a 200x bet payout. During free spins, Treasure Chest Scatters on reels 3, 4, and 5 award 15, 20, or 25 spins.
This demo version lets players play for free and practice before playing for real money. Free Spins also include a Grand Nitro Meter, which can unlock a Grand Reward of 500x the bet when it reaches 15 points. Additional scatters can retrigger bonus spins, while Bomb Wild symbols may activate an Explode feature that finalises wins after the symbols settle.
