Sisters of Oz Wow Pot Slot Review

Sisters of Oz WowPot is a progressive jackpot slot game that is a collaboration between Triple Edge Studios and Microgaming. Microgaming, as you may know, is a trusted casino software company often regarded as the pioneers of online slots and casinos. Or the godfather of online slots. Whatever way you want to look at it - if you're playing at Microgaming slot, including Sisters of Oz WowPot, you know it's going to be good.

In our Sisters of Oz Wowpot slot review, you'll find out everything you'll need to know about the game, from how to play, what's so good about it (hint: the 4 progressive jackpots!) past jackpot winners, game tips and of course, which safe casinos we recommend playing it at. Like with all of our online slot reviews, we've played the game at length for real money - and we try to tell it like it is, including aspects we love and some we're not so crazy about. Let's get started, shall we?

Sisters of WowPot Slot Introduction

Sisters of WowPot slot was launched in 2021 and is part of the WowPot series of jackpots. The game is based on the famed tales of Oz by L. Frank Baum. This version, however, is about a sisterhood of glamourous witches, each wearing outfits that would make SheRa blush. The background sets the scene with the Yellow Brick Road and adorning the reels aside from the sisters, are icons including the Gold Book of Oz and five lower value alchemy/Potion bottle symbols.

There's a fair few stand out features to this slot game. The first is its progressive jackpot which starts the ball rolling at a minimum of £2,000,000 (which beats Mega Moolahs jackpot that seeds at £1 Million). Secondly, the graphics are sublime and so is the fantastical soundtrack. Thirdly, there are bags of in-game features to enjoy (which we'll get to in a moment, though if you can't wait then skip to slot features). Sisters of Oz WowPot is designed with 5 reels, 3 rows and 20 fixed paylines and is considered a low volatility slot game.

How To Play Sisters of Oz WowPot Slot

To play the Sisters of Oz slot, you will first need to find an online casino that offers it. For your convenience, and if you're looking to join a safe new casino, we've handpicked a bunch of UK licensed casinos that offer the game below. Once sorted, load the game up and set your betting levels. Simply use the plus/ minus buttons to adjust the game to your preferred levels based on your budget. Bets start at 20p and increase to a whopping £300 per spin. You can set the game on auto spin (up to 100) if you require and if you're not sure of anything, you can open the game rules and paytable at any time by clicking on the icon. Once happy with everything, now's the time to start spinning.

Sisters of Oz WowPot Slot Features

Whilst the standout feature is the 4 progressive jackpots, this game does offer several other fun in-game features to keep things thrilling during gameplay. They include your standard wilds, jumbo symbol blocks, synchronised reels and free spins with multipliers.


The Book of Oz symbol serves as both a wild and a scatter symbol. It substitutes all other symbols in order to create a win, but it can also trigger the bonus games too.

Stacked Symbols & Synchronised Reels

All four of the Sisters of Oz characters can come stacked with 2, 3, or 4 symbols high. If they meet in the central reels, they can create a jumbo block that joins a 3x4 space. This is known as the 'Synchronized Reels' feature. The 3×4 block is the equivalent of 12 standard symbols. When the feature starts, the 3×4 block lands first (in the centre) followed by reel 1 and then the fifth reel.

Free Spins Feature

When you land 3, 4 or 5 scatter symbols, you'll trigger 5, 7 and 10 free spins sequentially. What's more, you'll get 2x multipliers on every spin (doubling your win) and a jumbo block will spin in the central 3 reels. 2 scatters will also automatically award you an extra 3 free spins.

💡 Tip: Remember that the sister jumbo blocks can increase your chances of winning much more. What's more, the gold Book of Oz symbol serves a double purpose. It’s both a wild symbol, so it substitutes for all the standard symbols to make up a winning combination. It’s also a scatter which can trigger the free spins feature

WowPot Progressive Jackpot Feature

Every potion symbol may randomly have a little gold coin on it (an overlay symbol). When it appears, it will be collected in the jackpot pot. Every time it collects a gold coin, it could trigger the WowPot jackpot wheel. Once in, you're in line to win one of the four progressive jackpots, depending on where the wheel lands:

  • Mini Jackpot: Starts at £10
  • Minor Jackpot: starts at £100
  • Major Jackpot: starts at £50,000
  • WowPot Jackpot: starts at £2 million

These amounts are just the 'seeded' amounts, meaning this is the amount they start at. They are known to grow much higher before they are won!.

RTP % & Volatility

The Sisters of Oz WowPot RTP is 92%. This is somewhat lower than the usual range for progressive jackpot slots, though only marginally. The volatility is in the low -medium variance sphere, with a hit frequency of 28.18% (which awards a win on average of every 3.55 spins). Discounting the jackpots, the max win on the Sisters of Oz WowPot slot is 720 x your total stake. That might not be in the same stratosphere as winning several million in cash, but it will do nicely we're sure when you land it.


  • WowPot Jackpot Seeds at £2,000,000
  • Free Spins With x2 Multiplier
  • Fantastic Graphics, Theme & Soundtrack


  • Lower RTP% of 92%

Sisters of WowPot Mobile Slot

If you enjoy your casino games and slots on mobile, this game doesn't disappoint on any device. Playable across all, Sisters of Oz WowPot Slot is as good on the smaller screen as it is on the desktop. Maybe even better actually. Simply load the game at your chosen mobile casino and enjoy on the go with HD graphics and all of the same features and jackpots available. All of the casino sites we've listed below work faultlessly on mobile.

Sisters of Oz WowPot Slot Review Verdict

We cannot fault the graphics nor the number of in-game features that keep you mesmerised whilst playing. The sultry sisters do a fine job especially when they group together to form jumbo blocks. The RTP of 92% may seem very low for some players, but remember to take into account that this is a progressive jackpot slot, so we're used to seeing such low numbers for these. Whilst progressive jackpots can be a long shot mathematically, make sure you keep an eye on the free spins feature that comes with an x2 multiplier (which lead a 720 x stake wins on each free spin) plus don't forget that you only need 2 scatters to trigger them. (Though there's a low amount given on each bonus round, we can forgive that because they trigger regularly).

Lastly, there's also a popular Sister of Oz Jackpots slot too. It's practically identical in appearance, the only difference between the two is that it has 4 fixed jackpots instead of the WowPots 4 progressive jackpots. Typically, the RTP is higher at 95.83% and comes with max wins of 10,000 x your stake. It's great to have a choice because the Sisters of Oz game franchise is pretty decent. Not sure which to play? Ask yourself: do you want to play a lower RTP % with the chance of netting a progressive jackpot (£2 Million +) or play the higher RTP % version with a max win of 10,000x your stake?
