Coin UP : Hot Fire

Coin UP: Hot Fire by 3 Oaks Gaming is a three-reel, three-row slot released in February 2024. The game centres on a 3x3 grid where the main action is tied to the middle row, with the bonus round triggered when three symbols land there. In the demo version, players can play for free and use it to practice before playing for real money.

The core feature is the Bonus Game, which starts with three respins. During the round, bonus symbols lock in place as they are collected, while the counter resets with each new qualifying symbol. The game includes Sticky Coin symbols, Coin Up symbols and Multi Up symbols, with the latter adding multipliers to symbols below them. Jackpot tiers shown in the game include Mini, Minor, Major and Grand.

An Ultra Bonus Game can also be activated by filling a special meter, while a buy bonus option is available for direct access to the feature round. Coin UP: Hot Fire uses a coin-collection format rather than a traditional line-based slot structure, making the bonus mechanics the main focus of the review page and the demo launcher.
