To achieve the Free Spins feature you will need to land 3 or more Mrs Piggy (the Scatter) icons on the reels simultaneously.
You'll see a free spin, and multiplier amount on each scatter symbol, so for instance, one scatter might show 28 spins and a 2x multiplier and another fewer spins but a higher multiplier; you can pick the one that suits you. The maximum free spins are 28, and 6x is the maximum multiplier. In addition, if another scatter appears while playing the bonus round, more free spins are triggered. The Free Spins will max out at 28, and a 6x multiplier will be awarded for every Scatter symbol that appears during the Free spins feature.
The slot is playable instantly on a computer, mobile device, or tablet. There are ten different bet levels available. You can spin the wheel once by pressing the spin button in the control panel's centre. The auto-play feature allows you to spin the reels a certain number of times automatically.
For a game to remain popular for over ten years, it has to have a unique appeal. Piggy Riches has that appeal, so it remains a firm favourite with players. This slot was among the first games introduced by NetEnt several years ago, so you'll find the graphics and sound effects rather basic, but don't let that put you off playing because this game is massive fun.
For new slot players, the medium volatility will result in decent but not massive wins. However, the chances of bigger wins by activating the free spins bonus will keep experienced players happy too. All in all, if you are looking for an entertaining classic slot, then Piggy Riches should be at the top of your list.
