It has proven to be one of the studio’s most successful releases and combines the potential for big jackpot wins with fast moving gameplay and outstanding graphics.

Building on the popularity of contemporary vampires and witchcraft themes, like all Triple Edge Studio games Sisters of Oz has very high production values, with beautifully designed symbols, haunting music and constant action. There are also plenty of opportunities to win big, with four jackpot prizes, the biggest of which is potentially worth up to £250,000.

How to play

Sisters of Oz is a 5 reel, 4 row video slot where 20 paylines are automatically in play on every spin. Wins pay left to right (expect for scatter wins which pay anywhere on the reels) and are multiples of the line bet (scatter wins are multiplied by the total bet). Coins range in size from £0.01 to £1.25, so the minimum bet is £0.20, with a maximum wager of £25.

  • Book of Oz symbol acts as both a Wild and a Scatter
  • Wild substitutes for all other symbols, except the Jackpot Trigger symbol
  • Jackpot Trigger Symbols can appear over Potion symbols
  • Collecting Jackpot Trigger symbols can trigger a spin of the Jackpot Wheel
  • Scatter wins pay anywhere on the reels
  • Hitting 5x scatter symbols = 100x total bet (up to £2,500) + 10 free spins
  • Hitting 4x scatter symbols = 10x total bet (up to £250) + 7 free spins
  • Hitting 3x scatter symbols = 2x total bet (up to £50) + 5 free spins
  • Hitting 5x Red Witch symbols = 360x line bet (up to £450)
  • Hitting 5x Green Witch symbols = 80x line bet (up to £100)
  • Hitting 5x Purple Witch symbols = 60x line bet (up to £75)
  • Hitting 5x Blue Witch symbols = 40x line bet (up to £50)

Jackpot

The maximum jackpot you can win in Sisters of Oz is 10,000x (£250,000 when betting the max) for hitting the Mega Jackpot when you spin the Jackpot Wheel. In base play, the maximum win is £2,500 (when betting the max) for hitting 5x scatter symbols anywhere on the reels,

This is a high volatility slot game with a 95.83% RTP.

Special features

Free Spins Bonus

Hitting 3x, 4x or 5x scatter symbols anywhere on the reels triggers the Free Spins Bonus Round, with the number of spins determined by how many scatters activate the feature:

  • Hitting 5x scatter symbols = 10 free spins
  • Hitting 4x scatter symbols = 7 free spins
  • Hitting 3x scatter symbols = 5 free spins

All wins are doubled during free spins bonus round, and a Jumbo Block will appear on every spin. The Jackpot Wheel can be triggered during Free Spins Bonus round, with the Scatter and Jackpot Trigger symbols appearing on reels 1 and 5. Hitting 2x scatter symbols triggers 3 additional free spins.

Jumbo Blocks

Symbols are stacked on every reel, and symbol stacks can then combine on reels 2, 3 and 4 to form Jumbo Blocks. A full Jumbo Block spans 3 x 4, and significantly increases the potential for big wins.

Jackpot Wheel

The Jackpot Wheel is triggered through collecting Jackpot Trigger Symbols, which can appear over Potion symbols.

Once activated, you spin the wheel to win one of four guaranteed jackpots:

  • Mega Jackpot = 10,000x total bet (up to £250,000)
  • Major Jackpot = 500x total bet (up to £12,500)
  • Minor Jackpot = 50x total bet (up to £1,250)
  • Mini Jackpot = 15x total bet (up to £375)

Graphics and Sounds

Although Triple Edge Studios slots are known for the quality of their artwork and production values, Sisters of Oz exceeds even its own exceptionally high standards. The four sexy witch characters dominate the game, especially when they animate after a win or expand to fill the reels in a Jumbo Block. The classic yellow brick road appears in the background behind the reels, but otherwise this is a very modern take on witchcraft (along the lines of the Twilight series).

The background music is appropriately haunting, creating an ominous atmosphere, and there is an alluring voice over when you hit a big win and at other times, which all contribute to the intense atmosphere of the game.

Conclusion

This is an exceptional game and one of the best Triple Edge Studios slots we’ve played. Dedicated slots players will want to play this game for the high variance and potential huge payouts, while it will also have appeal to those for whom the game’s visuals and graphics are more important.

The theme is exceptionally well realised, with exciting characters and a captivating colour theme, and the game looks good on any size of screen. What’s more, with expanded symbols, a combined wild/scatter, and a free spins bonus round, there is plenty of fast moving gaming action and plenty to keep players engaged throughout.

If you want to fall under the Sisters of Oz spell, you can check out the game for yourself at one of our recommended UK online slot sites.
