Coin Up: Hot Fire

Coin UP: Hot Fire is an all-or-nothing 3×3 slot built around coin action. In the base game only coin symbols land, and lining up three coins across the middle row triggers the Hold & Win bonus. The feature starts with 3 respins on an expanded grid, and every new coin that appears locks in place and resets the spin counter, keeping the round alive while values stack up. Each coin carries a multiplier of up to 5×, turning small clusters into exciting wins. Coin UP symbols raise the values of adjacent coins, while Multi UP symbols add multipliers to random positions for rapid jumps in potential. Collect symbols gather all visible coin values into a single boosted total before play continues. Mystery Jackpot symbols can reveal Mini, Minor or Major icons. Filling all nine positions with coins awards the Grand Jackpot of 500× the play size. With simple rules, bright visuals and single decisive bonus, the Coin UP: Hot Fire slot suits players who enjoy watching one round build toward a dramatic coin-packed finish.
