Wizard of Oz slots by WMS / Light & Wonder: every version, RTP from the maker (95.95% Emerald City), bonus features and where the official games really run.
Disclosure We may earn a commission when you click links to casinos. It never changes the facts we report. About this guide
Wizard of Oz slots are a family of licensed games from WMS, now part of Light & Wonder, not a single machine. Online, the best-known title is The Wizard of Oz Emerald City, which Light & Wonder lists at 95.95% RTP; newer releases such as Over the Rainbow went live in 2025 as a BetMGM exclusive in New Jersey, Michigan, Pennsylvania and Ontario. As of October 2026 we could not verify any crypto casino carrying an official version, so this page has no casino list and explains where the games really run.
Below you will find what the maker itself publishes for each version, how the classic 30-line game plays, and how to tell the licensed game apart from Oz-themed lookalikes. Figures come from Light & Wonder’s own catalogue and press releases first, and from licensed operators only where the maker is silent. Anything nobody publishes is marked as such rather than guessed.
Which Wizard of Oz slot are you looking at?
Five different products share the name, and they behave very differently. A casino floor cabinet in Las Vegas, an online slot in a UK lobby, an instant-win game and a free phone app can all carry the yellow-brick-road artwork. Before comparing RTP, bet sizes or bonuses, it helps to know which one you have in front of you.

Land-based cabinets add more names again: I’ll Get You My Pretty (5 reels, 25 lines, 800 credits max bet) and The Wicked Witch of the West Crystal Ball (3 reels, 9 lines, 250 credits max bet) are both listed on Light & Wonder’s gaming site. Those machines are only on casino floors.
Who is behind the game: WMS, Scientific Games and Light & Wonder
WMS built its reputation on licensed themes for casino floors, and The Wizard of Oz became one of its best-known brands. Scientific Games bought WMS in 2013 and renamed itself Light & Wonder in 2022, which is why newer pages carry the Light & Wonder name while older reviews still say WMS. Online versions run on the NYX Gaming servers that Light & Wonder now operates: the demo links on its catalogue pages point to NYX hosts, and BetMGM lists NYX Gaming as the software provider for Over the Rainbow.
Rights sit with Turner Entertainment Co., the Warner Bros. Discovery company that owns the 1939 film. On 12 July 2023 Light & Wonder announced an expanded multi-year licensing deal with Warner Bros. Discovery Global Themed Entertainment. That release says the branded titles are “set to hit regulated markets worldwide” through its OpenGaming platform and names The Wizard of Oz: Road to Emerald City as a land-based hit due to move online.
Then, on 5 March 2025, Light & Wonder announced The Wizard of Oz slots at BetMGM Casino, calling them exclusive to that operator. Over the Rainbow was first, available in New Jersey, Michigan, Pennsylvania and Ontario, and the company said it was the first of several Oz titles planned across 2025 and 2026.
The classic 30-line online game, feature by feature
Most players who search for the online Wizard of Oz slot mean the older 30-line video game with Glinda, the Winged Monkeys and a pick bonus on the yellow brick road. Light & Wonder’s catalogue page for The Wizard of Oz Emerald City gives the RTP and bet range but no rules text, so the feature description below follows the game page at Slingo, a UK-licensed operator that files the game under that same Emerald City name.
- Layout: 5 reels and 30 paylines, with a selectable number of lines and bet size.
- Wild: the Wizard of Oz symbol substitutes for everything except the Emerald City jackpot symbol and the feature icons.
- Glinda the Good Witch: she can appear at random during any base-game spin and turn between one and five reels into wilds.
- Oz Pick: three Emerald City symbols landing together on reels 1, 3 and 5 open a pick screen with three possible outcomes.
- Cash Win: an instant credit award from the pick screen.
- Winged Monkeys: 8 free spins; monkeys fly across the reels and change symbols into wilds.
- Road to Emerald City: a multi-level pick game where emeralds hide cash prizes or a character who moves you to that character’s level.
Slingo’s page puts the minimum stake at £0.30, while Light & Wonder’s catalogue entry lists 0.35 to 700 per spin. Operators set their own bet ladders within the maker’s limits, so the range you see depends on the casino and currency. Neither page publishes volatility, hit frequency or a maximum win, and we will not invent them.

How a typical session unfolds
Base-game spins carry most of the action. Small line wins from the film symbols (the tornado, Dorothy’s house, the ruby slippers, Toto) come often enough to slow the drain on a balance, while bigger hits usually need the wild or a Glinda visit. Because Glinda can arrive on any spin with no trigger symbol, a dull run can turn in one spin when several reels go wild at once.
Three Emerald City symbols on the odd reels lead to the pick screen. Here the outcome is a choice in name only: the maths behind each pick is fixed by the game, and no selection pattern changes the long-run return. Our guide to Wizard of Oz odds explains why, and the step-by-step rules page walks through bet settings, lines and each bonus screen.
Over the Rainbow plays differently. Its 5×4 grid adds Respins when two bonus symbols land, a Balloon Jackpot through State Fair symbols, and a Free Spins round in which up to seven character features can be active, according to Light & Wonder. Glinda appears here too, randomly replacing reels with a Glinda wild, and a Tin Man, Cowardly Lion or Scarecrow feature may join her.
Where the official games actually run
Real-money play on the licensed titles happens at regulated casinos. Light & Wonder’s catalogue tags Emerald City to the UK, Malta, Gibraltar, Alderney, Belgium, Greece, New Jersey and Quebec. In the United States, Over the Rainbow launched only at BetMGM, and BetMGM’s own review calls it a BetMGM exclusive. Land-based cabinets sit on casino floors in many countries, chosen by each venue.
Crypto casinos are a different story. Light & Wonder describes its Warner Bros. titles as built for regulated markets, and we could not find an official Wizard of Oz game in the crypto casino lobbies we checked in October 2026, including Stake, BC.Game, BitStarz, 7Bit, mBit and FortuneJack. That is why this page carries no casino list. Our page on crypto casinos and Wizard of Oz sets out the checks in full and what to look for if a site claims to have the game.
Some readers live where these games are legal and licensed. Over the Rainbow went live in March 2025 at BetMGM in New Jersey, Michigan, Pennsylvania and Ontario, the launch markets Light & Wonder named; state coverage can change, so BetMGM’s own state list is the reference. UK readers will find Emerald City at UK Gambling Commission licensees. We do not recommend or link to operators in those markets.
Lookalikes: same name, different game
Oz is a public-domain story in its book form, and several studios have released slots with Oz names. Only Light & Wonder (formerly WMS) holds the film licence for the Judy Garland look, the ruby slippers as they appear in the film, and the Turner trademark notices. Three quick checks separate the real thing from a copy:
- Open the game’s info or paytable screen and read the provider name: it should say Light & Wonder, WMS or NYX, not another studio.
- Look for the “THE WIZARD OF OZ and all related characters and elements © & ™ Turner Entertainment Co.” notice that Light & Wonder prints with its Oz titles.
- Compare the RTP shown in the game with the catalogue figure: 95.95% for Emerald City, 95.36% for Ruby Slippers DUAL.
A lobby that lists “Wizard of Oz” under an unfamiliar studio is offering a different game with different maths. That may be fine to play, but none of the figures on this site apply to it.
Free versions and bonus offers
Light & Wonder’s catalogue page for Emerald City has a Play Demo button behind an 18+ age check, which is the cleanest way to see the real game without staking anything. Zynga’s Wizard of Oz Slots app is free too, but it contains its own machines built for the app rather than the casino maths. Our free play guide compares both. For promotions, the Wizard of Oz bonus page explains how in-game free spins differ from casino free-spin offers and why a crypto casino spin offer cannot be used on a game the casino does not carry.
Our verdict on the Wizard of Oz slot family
As a game, the 30-line Emerald City title is a well-made, film-heavy slot with a slightly below-average RTP for modern online releases (95.95%) and three distinct bonus routes. Over the Rainbow is the stronger modern build, with a richer free-spins round and published jackpot multipliers, but it is confined to BetMGM in the US and Ontario.
For crypto players the honest answer is short: the official games are not where you play. Treat any crypto lobby claiming the licensed title with suspicion until the provider screen confirms it, and set a budget before you spin anything. Play is for adults only (18+, or 21+ where local law says so), and help is listed on our responsible gambling page.

Wizard of Oz slot: common questions
Who makes the Wizard of Oz slot?
The licensed Wizard of Oz slots come from WMS, which became part of Scientific Games in 2013; Scientific Games renamed itself Light & Wonder in 2022. The film rights belong to Turner Entertainment Co., and Light & Wonder builds the games under a licence from Warner Bros. Discovery.
What is the RTP of the Wizard of Oz online slot?
It depends on the version. Light & Wonder’s catalogue lists 95.95% for The Wizard of Oz Emerald City and 95.36% for Wizard of Oz Ruby Slippers DUAL. BetMGM gives up to 96.2% for Over the Rainbow. Land-based machines run whatever setting the casino picks from the maker’s options.
How many paylines does Wizard of Oz have?
The classic 30-line online game uses 5 reels and 30 paylines, according to the description on Slingo’s page for it. Over the Rainbow is listed by BetMGM with up to 45 paylines online, while the land-based Over the Rainbow cabinet runs 5 reels and 30 lines.
Can I play Wizard of Oz slots with Bitcoin?
We could not verify any crypto casino that carries an official Light & Wonder Wizard of Oz title as of October 2026. Light & Wonder says its Warner Bros. titles go to regulated markets, and the game pages in its catalogue are tagged to licensed jurisdictions such as the UK, Malta and New Jersey.
Is the Wizard of Oz Slots app real money?
No. Zynga’s Wizard of Oz Slots app is a social game: its Google Play listing says it does not offer real money gambling or a chance to win real money or prizes. Coins can be bought but never cashed out.
What is the biggest win on Wizard of Oz?
Light & Wonder does not publish a maximum win on its Emerald City catalogue page, so we do not quote one. For Over the Rainbow, Light & Wonder names a 1,000x top jackpot, and BetMGM’s review lists a maximum payout of 3,693x the wager.
