Northern Boom: Hold and Win

Northern Boom is a winter-themed video slot by Belatra Games with 5 reels, 25 paylines and an RTP of 94.14%. The game combines standard spin play with a hold and win-style bonus, free spins, a four-level jackpot feature and a risk game. A super-symbol can appear on the second, third and fourth reels, replacing nine smaller symbols.

Free spins are triggered by three or more scatter symbols, with additional scatters during the bonus round able to award more spins. The jackpot bonus begins when six or more credit symbols land on screen, then three respins follow with chances to collect the Grand, Midi, Mini or Mega Jackpot, depending on the symbols locked in place.

The demo version is available to play for free, giving players a way to practice before playing for real money. Northern Boom also includes a Buy Bonus option for quicker access to features, plus a risk game that can double a win or multiply it by four by guessing card colour or suit.
