Standard play is, more or less, your typical 3-row, 5-reel pokies affair. There are 20 paylines in Penguin Vacation, which isn't too bad, and it's possible to rack up some reasonable wins in standard play.
However, the bonus round is an entirely different story. When a round of free spins is triggered, players are given some ice blocks to choose from. With a bit of luck, it's possible to activate as many as 33 free spins and a multiplier that goes as high as 15x.
Of course, there's a trade-off here – sometimes players will only get 8-10 free spins and have to cope with a multiplier of just 2x. There's a nice jackpot to be had when playing Penguin Vacation – 10,000x your line bet – but the real sense of volatility comes from how much the end result of the bonus round can vary.
A multiplier of 15x can do INCREDIBLE things for your bankroll and, provided you're willing to take the times you only get a 2x multiplier in stride, this game throws out some of the most exciting bonus rounds online pokies have to offer.
