Coin Volcano is a BGaming slot, RTP 96.07%, high variance, Hold and Win mechanic. Five reels, three rows, 25 paylines. The theme is a volcano: lava, fire, molten coins.

Special Features
Six or more coins on one spin starts the Hold and Win round in Coin Volcano. Coins lock. Three respins begin. Any coin that appears during those respins locks too and sends the counter back to three. So the round keeps going as long as new coins keep showing up. Special coins carry multiplier values and mini, minor, major, or grand jackpot prizes. BGaming built the Coin Volcano game so that a full board pays at the maximum level. One grand jackpot coin appearing late in a long round changes the total in a serious way.
