Developer Coin UP: Hot Fire by 3 Oaks Gaming is a February 2024 3x3 slot built around the HIT the BONUS mechanic. The game uses a central-row trigger, where landing three symbols of any type activates the bonus game. A Sticky Coin symbol can remain in place until the feature starts, while Coin Up and Multi Up symbols appear on an extra row to affect the reels below.
In the bonus round, players receive three respins to collect bonus symbols shown as coins with different values. Each new symbol resets the respin count, and the feature can include Mini, Minor and Major jackpot values. Mystery and Mystery Jackpot symbols may add further rewards, while a Collect symbol gathers the current values. Filling all nine positions can trigger the Grand Jackpot.
The slot also includes an Ultra Bonus Game, unlocked by filling a special metre, with higher-value bonus symbols. Players can use the demo version to play for free and practice before playing for real money. The page near the launcher provides a brief view of the main mechanics, special symbols and bonus features.
