Sisters of Oz WOWPOT is a Triple Edge Studios fantasy slot released in August 2020 that connects a conventional payline game to the four-tier WowPot progressive jackpot. The slot arranges its Wizard of Oz cast across a 5x4 grid with 20 fixed paylines running from left to right, and builds its feature set around oversized Jumbo Block symbols rather than around cascades or expanding reels. Its bonus round doubles every win and guarantees a Jumbo Block on each spin, while the jackpot tiers are decided by a separate bonus wheel that sits outside the payline game entirely.
Sisters of Oz WOWPOT presents each round on five reels of four rows and evaluates 20 fixed paylines from the leftmost reel rightwards. The four sister symbols occupy the upper end of the paytable and arrive in stacks of two, three or four positions, which is what allows a single reel to be covered by one character.
Sisters of Oz WOWPOT separates its two reward structures deliberately. The payline game produces ordinary combinations and the free spins round, while the WowPot progressive is awarded through a bonus wheel whose outcome does not depend on any line win the reels have produced.

Sisters of Oz WOWPOT is listed by Wildz with a default RTP of 92.00% and high volatility. The stake range and the currency in which the jackpot tiers are displayed can vary by market and by operator, so the information panel inside the version being played is the relevant source for its current betting conditions.
Sisters of Oz WOWPOT pays when matching symbols land on consecutive reels along one of its 20 fixed paylines, beginning at reel one. All twenty lines are active on every spin, so the stake covers the full set rather than a selected number of them.
Sisters of Oz WOWPOT adds its two feature layers on top of that base. Stacked sister symbols can merge into a Jumbo Block across the middle of the grid, three or more Book of Oz scatters open the free spins round, and the WowPot bonus wheel can bring the round to a progressive award independently of what the paylines have done.
Sisters of Oz WOWPOT gives its four sister symbols the ability to combine into a single oversized block measuring 3x4 positions. A full block of that size covers reels two, three and four completely, which turns twelve grid positions into one repeated character and can place that symbol on every active payline at once.
Sisters of Oz WOWPOT determines the appearance of a Jumbo Block through the same random process that governs every other spin outcome. The block cannot be summoned by raising the stake, by playing longer or by following a particular betting pattern, and a covered set of middle reels still requires matching symbols on reels one and five to complete the longest combinations.
Sisters of Oz WOWPOT is linked to WowPot, a networked progressive shared across the participating titles in the Games Global range. The pool is fed by play on all of those games rather than by this slot alone, which is why the amounts on offer can stand far above anything the paytable itself describes.
Sisters of Oz WOWPOT awards the progressive through a bonus wheel rather than through the reels. An award is therefore independent of the paylines and of the free spins round, and the game’s own win potential should be read as excluding the jackpot rather than including it.
Sisters of Oz WOWPOT carries four jackpot tiers: Mini, Minor, Major and WowPot. Their published starting values are 10, 100, 50,000 and 2,000,000 respectively, and each tier resets to its seed after it has been won before climbing again with continued network play.
Sisters of Oz WOWPOT selects the tier on the wheel, so which of the four is reached is not something a player can steer. The displayed currency and the exact seed presentation can differ between operators, and no tier becomes more likely because a large amount has gone unclaimed for a period.
Sisters of Oz WOWPOT opens its bonus round when 3, 4 or 5 Book of Oz scatters land, awarding 5, 7 or 10 free spins in that order. Every win during the round is subject to a 2x multiplier, and a Jumbo Block is guaranteed on each individual free spin rather than left to chance as it is in the base game.
Sisters of Oz WOWPOT allows the round to be extended when 2 scatters land during it, adding 3 further free spins to the remaining total. The number of extensions is not capped by a published limit, but each one depends on the scatters actually appearing, so a longer round cannot be arranged by the player.
Sisters of Oz WOWPOT carries a theoretical RTP of 92.00% in the version listed by Wildz. This sits below the level common to non-jackpot video slots, and the difference is accounted for rather than unexplained: a share of every stake is diverted into the shared WowPot pool instead of being returned through the paytable.
Sisters of Oz WOWPOT expresses that percentage as a long-term calculation across a very large volume of wagering, not as the expected outcome of one session. The figure quoted here is the one Wildz lists for the version it serves, and the in-game information panel confirms the setting attached to any particular version.
Sisters of Oz WOWPOT has a high-volatility profile as listed by Wildz. Its combination of stacked characters, an all-or-nothing Jumbo Block and a short doubled bonus round produces uneven results, so stretches without a meaningful return can sit alongside occasional concentrated wins.
Sisters of Oz WOWPOT volatility describes how payouts are distributed rather than when they will arrive. A run of losing spins does not increase the probability that a large result must follow, and the progressive wheel is no closer for having been absent.
Sisters of Oz WOWPOT does not have a single maximum win figure that published sources agree on, so none is stated here. The largest award the game can produce is the WowPot tier, which is a pooled cash amount rather than a multiple of the stake and therefore cannot be expressed as an Nx ceiling at all.
Sisters of Oz WOWPOT builds its largest payline results from the same two mechanics in combination: a 3x4 Jumbo Block filling the middle reels while the 2x free spins multiplier applies. Both are outcomes of the random game system, and neither the block nor the multiplier can be secured by stake size or by the timing of a spin.
Sisters of Oz WOWPOT can be played in the United Kingdom through an online casino that holds the appropriate Gambling Commission licence and carries the Triple Edge Studios title. After account registration and age verification, a player can open the game, read its rules, set a permitted stake and spin the twenty fixed lines.
Sisters of Oz WOWPOT stakes are also governed by the statutory online slot limits in force in Great Britain. Players aged 18 to 24 can stake no more than £2 per game cycle, while customers aged 25 and over have a £5 maximum; these limits have applied since 21 May 2025 and 9 April 2025 respectively, and they apply to a jackpot slot exactly as they do to any other.
Yes, Sisters of Oz WOWPOT can be played on compatible smartphones and tablets. Triple Edge Studios supplies the game in desktop and mobile builds, and the 5x4 grid, the Jumbo Blocks and the jackpot wheel all adapt to a smaller screen without any mechanic being removed.
Sisters of Oz WOWPOT mobile play normally runs through a licensed casino site in a supported browser. The same WowPot pool is shared between the desktop and mobile versions, and the identical age-verification, licensing and stake-limit requirements apply when the game is opened on a phone.
Sisters of Oz WOWPOT may be offered to players in the United Kingdom by online casinos that hold the appropriate Gambling Commission licence and carry the Triple Edge Studios game. British customers must be at least 18 years old, complete the required verification, and remain within the statutory online slot stake limits while playing.
Sisters of Oz WOWPOT is listed on Wildz internationally, but Wildz states that customers visiting from the United Kingdom are redirected to partner casinos. UK players should therefore use the Gambling Commission public register to confirm that the casino they end up using is licensed for the British market, rather than assuming the international Wildz platform accepts UK registrations.
Sisters of Oz WOWPOT real-money play in the United Kingdom sits inside the regulatory system supervised by the Gambling Commission. Operators serving customers in England, Scotland and Wales must hold the appropriate licence, and the Commission maintains a public register where a gambling business can be checked before any money is deposited.

Sisters of Oz WOWPOT players should also distinguish Great Britain from the United Kingdom as a whole when reading Gambling Commission rules. The Commission regulates gambling in England, Scotland and Wales, while Northern Ireland operates under a separate legal framework and is not governed by the Gambling Act 2005 in the same way.
Sisters of Oz WOWPOT pays when matching symbols land on consecutive reels along its 20 fixed paylines, read from reel one. Stacked sister symbols can fuse into a 3x4 Jumbo Block across the middle reels, Book of Oz scatters open the free spins round, and a separate bonus wheel awards the WowPot progressive tiers.
Sisters of Oz WOWPOT is listed by Wildz with a theoretical RTP of 92.00%. That sits below the level usual for non-jackpot video slots because part of every stake funds the shared WowPot pool instead of returning through the paytable. The in-game information panel confirms the setting in use.
Yes. Triple Edge Studios supplies desktop and mobile builds, and the 5x4 grid, the Jumbo Blocks and the four-tier jackpot wheel all carry over to a phone or tablet with no feature removed. Both builds draw on the same WowPot pool, so a mobile spin can win the same progressive tiers.
Sisters of Oz WOWPOT is linked to WowPot, a networked progressive fed by several Games Global titles. Four tiers — Mini, Minor, Major and WowPot — are seeded at 10, 100, 50,000 and 2,000,000, and are awarded on a bonus wheel independently of the paylines and the free spins round.
