Vie for the chance to win one of four generous progressive prizes in Sisters of Oz WowPot from Microgaming and Triple Edge Studios. This 20-payline game offers up plenty of generous perks, including free spins, jumbo symbols and multipliers – with a WowPot that seeds at a whopping 2,000,000 coins!

Theme and Graphics

Sisters of Oz Wowpot from Triple Edge Studios is part of the same universe as the Book of Oz games from Microgaming, with sultry characters and a more grown-up aesthetic. Just like the other games in the series, the graphics are very impressive with symbols that feature all sorts of dazzling positions, and three stunning wizards.

RTP and Variance

The RTP of Sisters of Oz is 95.83%. This is a bit lower than we normally see from modern online slot releases, since most games tend to have payout percentages over 96%.

It is also a medium volatility game, so you can expect to see wins fairly frequently. Combining this volatility with a four-level progressive jackpot is a great mix, and offers up plenty of excitement for players.

How to Win

There are 20 paylines in Sisters of Oz, and winning combinations are made by landing three or more matching symbols on any of them. The red sister is the most generous symbol of the bunch, paying out a prize of 18x your stake. All three of the sister symbols can appear in stacks, as well, to help boost your odds of winning.

Free Spins and Bonuses

When you land three or more scatters, you’ll trigger the free spins round. The number of free spins you receive depends on the number of scatters that trigger the bonus:

  • 3 scatters for 5 free spins
  • 4 scatters for 7 free spins
  • 5 scatters for 10 free spins

An initial offering of between 5 and 10 free spins is pretty poor. Most games tend to provide 10 to 20, so Sisters of Oz falls a bit short here, but all wins that you land during the bonus are doubled so that’s some consolation.

Another perk is that it just takes 2 scatters to get more free spins. When this happens, you’ll get 3 more spins. The scatters appear on reels 1 and 5 during the free spins round, along with progressive trigger symbols.

Progressive Jackpots

There are four progressive jackpots that you can trigger while playing Sisters of Oz Wowpots. To gain entry into this bonus round, you’ll have to land progressive trigger symbols, which appear over potion symbols in the base game and on the first and land reels during the free spins round. The four jackpots are:

  • Mini Jackpot: seeds at 10 coins
  • Minor Jackpot: seeds at 100 coins
  • Major Jackpot: seeds at 50,000 coins
  • WowPot: seeds at 2,000,000 coins

While WowPot is its own Microgaming slot, it’s not actually related to this game. The WowPot in Sisters of Oz is its own entity – but, we anticipate that more games will be added to this jackpot pool in the future, similar to the Mega Moolah network.

Overall Review

Sisters of Oz WowPot from Microgaming and Triple Edge Studios offers players an exciting online gaming experience, and is a great addition to this series. Book of Oz is already good fun (especially its Hyperspins remake), so it’s nice to see these developers adding to the collection.

The base game is pretty barren when it comes to bonus features, but we do like the Jumbo Blocks features. This can really help to ramp up the wins as you spin the reels.

At first, we were a little bit disappointed at the initial number of free spins granted. However, once we realized how easy it is to get more free spins, (since only two scatters are required), it wasn’t really an issue. Combined with the doubled wins, the free spins bonus is quite impressive.

Then, there’s the progressive jackpot. You don’t see progressive prizes in the online slots market all that often anymore, and it’s good to see that Microgaming and Triple Edge Studios are offering players the opportunity to land some life-changing payouts.
