Sisters of Oz WowPot Slot Review by Microgaming
Sisters of Oz WowPot is a progressive jackpot slot from Microgaming. It was made with Triple Edge Studios. It is a sequel to the popular Book of Oz slot.
The game has five reels, four rows and 20 paylines. Jumbo Blocks, free spins with a multiplier and four progressive jackpots drive the action.
This review covers the bet range, the symbols and the jackpots. We could not open the developer’s game page. As a result, the figures come from our earlier review and are marked that way.
Sisters of Oz at a Glance
| Developer | Microgaming with Triple Edge Studios |
| Theme | Wizard of Oz fantasy |
| Layout | 5 reels, 4 rows, 20 paylines |
| Bet range | $0.20 to $300, according to our earlier review |
| RTP | 92.00% according to our earlier review |
| Volatility | Medium, per our earlier review |

| Free spins | 5, 7 or 10 spins with a 2x multiplier |

Theme, Graphics and Sound
The yellow brick road runs through the background. Four sisters appear as the main characters. The look is bold and colourful.
The soundtrack is fantastical and fits the theme well. As a result, the game feels like a storybook adventure.
Fairy tale themes remain popular. Our guide to popular slot themes online covers other styles.
Betting Range
Our earlier review listed bets from $0.20 to $300 per spin. That is a very wide range. It suits small budgets and high rollers.
Progressive jackpot games often take part of each bet for the prize pool. Choose a stake you are happy to play over a long session.
RTP and Volatility
Our earlier review gave the RTP as 92.00%. That is clearly below the 96% many slots offer. Jackpot slots often have lower base returns because the pool takes a share. Our guide to RTP and online slots explains the figure.
The same review rated the game medium volatility. We could not verify either number, so check the game info at your casino.
Symbols and Paytable
The low symbols are potion bottles. The four sisters are the high symbols. The pink-haired sister pays the most.
According to our earlier review, three, four or five of her pay 0.5x, 1x or 18x your stake. All four sisters can appear as Jumbo Blocks.
| Symbol | Role |
|---|---|
| Gold Book of Oz | Wild, scatter and bonus trigger |
| Four sisters | High paying symbols |
| Potion bottles | Low paying symbols |
| Gold Oz symbol | Progressive jackpot symbol |
The Gold Book of Oz
The Gold Book of Oz has two jobs. It acts as a wild and replaces other symbols to complete wins. It is also the scatter and starts the bonus round.
Jumbo Blocks
The sisters can appear in tall blocks, 2, 3 or 4 symbols high. The blocks can combine on the middle three reels. Together they can form a huge 3×4 block, worth 12 normal symbols.
Our earlier review called this the Synchronised Wheel Feature. It said wins can reach 720x your stake.
Free Spins
Three, four or five Book of Oz symbols start the free spins. Our earlier review said you get 5, 7 or 10 spins. It also said the bonus pays 2x, 10x or 100x your total stake.
Each winning combination gets a 2x multiplier boost. Scatters on reels 1 and 5 add three more spins with no limit. We could not verify these rules.
The WowPot Jackpots
The gold Oz symbol is the progressive jackpot symbol. It can sit on top of the potion bottles. Collect enough and you get a chance to spin the Progressive Wheel.
Four jackpots are attached to the wheel. Our earlier review gave their starting values.
| Jackpot | Starting value (earlier review) |
|---|---|
| Mini | $10 |
| Minor | $100 |
| Major | $50,000 |
| WowPot | $2 million |
Strategy and Bankroll Tips
- Choose a stake that gives you at least 150 spins.
- Treat the progressive jackpots as a bonus rather than a plan.
- Check the current jackpot values before you play.
- Set a loss limit before you start.
- Take regular breaks.
No tip changes the odds. Every spin is random, and earlier results never affect the next one.
Mobile and Demo Play
We could not confirm the mobile status of this slot. Check your casino’s game list on your phone or tablet.
A demo is a safe way to learn the features. Our guide to free online slots explains how to practise.
How a Typical Session Plays
The base game is steady. Potion bottles pay small wins, and sisters add bigger moments. Jumbo Blocks bring extra spark.
The tension rises when Oz symbols collect. Each one brings the jackpot wheel a little closer.
The free spins then deliver a different mood. Multipliers and blocks can build wins fast. However, the jackpot remains a long shot, so enjoy the ride.
Sisters of Oz Compared with Other WowPot Slots
| Area | Sisters of Oz | Many WowPot slots |
|---|---|---|
| Jackpots | 4 tiers | 4 tiers |
| Top jackpot start | $2 million | $2 million |
| Special feature | Jumbo Blocks | Varies |
| Base RTP | 92.00% (earlier review) | Often lower than non-jackpot slots |
The Jumbo Blocks make this WowPot slot stand out from its rivals.
Why Jackpot Slots Have Lower RTPs
Part of every bet in a progressive slot goes to the jackpot pool. That means less of your stake returns in normal wins. As a result, the base RTP often looks lower.
The trade-off is the chance at a very large prize. For example, a WowPot jackpot starting at $2 million is far above any normal win.
However, the odds of hitting the top jackpot are very small. For that reason, it is best to enjoy the base game and the free spins.
If you want a higher return in normal play, a non-jackpot slot may suit you better.
Getting Started with Sisters of Oz
Start with the demo if your casino offers one. Spin for a few minutes and watch how the main features work. This costs nothing and shows you the pace of the game.
Next, open the paytable. It shows the symbol values and the rules at your stake. As a result, every spin makes more sense.
Then move to real money at a small bet. A modest stake gives the bonus round time to appear. Finally, decide your limit before the first spin and keep to it.
Playing Responsibly
Progressive jackpots can tempt you to bet more than you planned. Set a budget before you play and keep to it. Use deposit limits and reality checks if your casino offers them.
Players must also be of legal gambling age in their country. Never chase losses. Stop if gambling stops being fun.
