Microgaming and Triple Edge Studios have collaborated on yet another high roller slot. The latest release is called Sisters of Oz and the results are as impressive as would be expected. As the name suggests, Sisters of Oz is loosely based around the famous tale of the Wizard of Oz.

Sisters of Oz features 5 reels, 4 rows, 20 fixed paylines and a 95.83% RTP. As with many high roller slots, the central draw is the jackpot system. Unlike a progressive jackpot system, this online slots game has fixed jackpots that offer increasingly enriching rewards.


Fans of the source material may be a bit taken aback with this representation of the wicked witches being a little different. Gone are the green skin and warty noses, replaced by sisters that wouldn’t be out of place in a fashion magazine. Still, the graphics are incredible as far as online slots go, and there is plenty to be impressed by. The highest paying symbols are the 4 sisters. Each is associated with a colour, red, green, purple and blue, and matching 5 of a kind pays up to 18x the original bet. The lower paying symbols are depicted by potion bottles rather than playing cards.


As with other high roller slots, the idea of the game is match symbols in a sequence. Once a bet is placed, the reels are spun, and any wining combinations paid out. The higher the value of the symbols that match on the reels, the bigger the payout.

For high roller casino players looking for a huge win, the Bonus Wheel in Sisters of Oz is where the real magic is. Bonus symbols are gathered during the base game, and eventually trigger the Bonus Wheel. The prizes awarded from spinning the Wheel are not progressive jackpot payouts, so the amounts are fixed. A Mini jackpot pays 15x your bet, a Minor 50x, a Mega 500x, and a Mega a whopping 10,000x your bet. 


Sisters of Oz is ideal for those who enjoy high limit online slots entertainment. The lowest accepted bet is 0.20, and highest a lofty 300.00 per spin.

In terms of features, it is a high roller slot that has plenty going on. At random, the 3 central reels may synchronise, and trigger the Jumbo Symbol special. This means that any of the witches will spin as larger versions of themselves, potentially awarding higher payouts.

Then there’s the Golden Book, which acts as both a Scatter and Wild symbol. If either of these symbols land simultaneously anywhere on the reels 3, 4 or 5 times, a respective 5, 7 or 10 Free Spins are awarded. During Free Spins, the centre 3 reels are always synchronised, and the witches appear as Jumbo icons, increasing your chances of a win.


Sisters Of Oz can be enjoyed at many high roller casinos, but for the very best overall real money gaming experience, we recommend playing at Betsson. Not only is this site secure, licensed and reputable, it’s also packed full of bouses and has a wealth of online slots and other games on offer.
