About the Coin UP: Hot Fire game
Coin Up: Hot Fire online slot machine is another spectacular game from 3 Oaks Gaming that uses the Hold and Win mechanic, combining the classic 3x3 layout with a hot, fiery theme. This game is designed for those who like retro style but don't want to sacrifice the serious winning potential offered by modern features. Behind the simple layout lie exciting bonuses, dynamic symbols and prizes of up to 500x.
Game mechanics, features, and RTP
Coin Up: Hot Fire uses a fixed 3x3 reel system with only one payline running across the middle row. The RTP is 95.75%, and the game has high volatility, so wins don't come often, but when they do, they can be significant. During the base game, the goal is to spin three coin symbols on the middle row to activate the Hold and Win bonus round.
The bonus round starts with three re-spins. Each time you spin a new coin or special symbol, the number of re-spins resets to three. The coin symbols have bet-based multiplier values (e.g., 2x, 5x, 10x, etc.) that are added up at the end of the round. The goal is to fill as many positions as possible on the 3x3 grid to maximize your winnings.
The various feature symbols make the bonus round extremely varied:
● Sticky Coin: can appear in the base game and sticks to the reel until the bonus round. Offers up to a 5x multiplier.
● Coin UP: increases the value of the coins below it. When the coins reach level 5x, they can be converted into Mystery Jackpot symbols.
● Multi UP: an exciting multiplier symbol that increases the value of the other coins on the grid.
● Mystery Jackpot: Revealed at the end of the bonus round, it can award a Mini (10x), Minor (20x) or Major (50x) jackpot.
● If you manage to fill all the fields, the total prize automatically increases to a 500x Grand Jackpot.
