Features Coin UP: Hot Fire is a 3x3 slot from Booongo built around a central row feature rather than standard paylines. In the base game, three symbols of any type on the middle row activate the HOLD & WIN bonus round, while STICKY COIN symbols remain locked in place until the feature begins. Players can use the demo version to play for free and practice before playing for real money.
The bonus game includes three respins, with new MONEY SYMBOLS, JACKPOT SYMBOLS, and special MYSTERY SYMBOLS joining the round. MINI, MINOR, and MAJOR jackpot symbols can appear, while a MYSTERY JACKPOT SYMBOL turns into one of these values at the end of the feature. A COLLECT SYMBOL may also land and gather the values from MONEY SYMBOLS, STICKY COINS, and JACKPOT SYMBOLS.
Extra mechanics include COIN UP symbols, which increase the value of symbols beneath them, and MULTI UP symbols, which add multipliers to the same reel. If all nine symbols are collected, the GRAND JACKPOT pays 500 times the wager. A buy bonus button is also available for instant access to the feature.
