Coin UP Volcano

Coin UP Volcano is a Hold and Win slot from 3 Oaks Gaming set against a dramatic backdrop of flowing lava and an erupting volcano. All regular symbol wins are paid within the Hold and Win bonus game rather than the base spins, which instead focus on lining up the trigger. Landing four symbols on an active payline launches the Hold and Win Bonus Game, expanding the play area from a standard 4x3 grid to a larger 4x6 layout. The top three rows start locked but can be unlocked as the round progresses. During the bonus, Bonus Symbols can land carrying fixed Mini, Minor and Major jackpots, while Mystery Symbols and Mystery Jackpot Symbols can reveal surprise rewards at any point. A Coin Collect Symbol gathers the value of every active Bonus Symbol when it appears. The bonus also features an UP Row sitting above the reels, bringing modifiers such as Reel UP, Mystery UP, Multi UP and Coin UP that can unlock blocked cells, upgrade Mystery Symbols into guaranteed jackpots, add multipliers or boost cash values. Super versions of these modifiers apply their effects across every reel rather than just one. Covering the bottom three rows awards the Grand Jackpot, while filling the entire 24 cell grid awards the top Royal Jackpot, giving Coin UP Volcano a satisfying long climb towards its biggest prizes.
