Coin UP Hot Fire by 3 Oaks Gaming — RTP & Analytics

Coin Up: Hot Fire by 3 Oaks Gaming features a 3x3 reel grid with a single fixed payline across the middle row, using numbered coin symbols instead of traditional icons. No payouts occur in the base game; wins only happen in the bonus round, triggered by landing three bonus symbols on the middle line, which grants three respins that reset with each new bonus symbol and feature sticky coins. Special symbols include Sticky Coins that hold position and award up to 5x the bet, Coin Up symbols that increment values below them (e.g., 1 to 2, up to transforming 5 into Mystery Jackpot), Multi-Up symbols that multiply values beneath them in stacks, Mystery Jackpot that changes to other symbols except Sticky Coin, Cash Collect that gathers and pays all reel values, and fixed Jackpot symbols (Mini 10x, Minor 20x, Major 50x, Grand 500x for all nine positions). The visual style employs a bold red background with animated flames, evoking a retro aesthetic enhanced by funky music, while the single-line focus and Hold and Win mechanics distinguish it from standard slots by concentrating all action in the bonus for high-volatility plays up to 1212x stake.
