Game Comparison
Five real money slots, one honest comparison. We place Crazy Ex-Girlfriend next to Gonzo's Quest by NetEnt, Book of Dead by Play'n GO, Starburst by NetEnt and Sweet Bonanza by Pragmatic Play. RTP, max win, volatility and licensed casinos, laid out in one table, five short write-ups and a clear verdict.
What Makes a Good Online Slot? A Quick Primer
A short chapter for anyone new to the genre. Five titles, one shared foundation underneath the different themes and artwork.
Online slots follow a simple structure. Reels spin, symbols land on a grid, and matching combinations along active paylines or clusters trigger a payout. Some titles layer free spins, expanding wilds or collectible symbols on top of that base game. The outcome of every spin depends on a certified random number generator, never on player skill.
The online slot market grew fast over the last decade. Providers such as NetEnt, Play'n GO and Pragmatic Play release new titles almost every month, and video slots now make up the largest single category in most casino lobbies. Gonzo's Quest, Book of Dead, Starburst, Sweet Bonanza and newer arrivals like Crazy Ex-Girlfriend all sit side by side there today. Most spins finish in three to five seconds, and published RTP for the category typically sits between 94 and 97 percent.
The appeal sits in the variance. A single spin can return nothing, or it can trigger a bonus round worth hundreds of times the stake, which keeps every session unpredictable.
What every slot on this list shares
- Paylines or clusters: a fixed number of ways to win per spin
- Bonus rounds: free spins, pick-and-click or tumble features
- Spin time: 3 to 5 seconds
- RNG certification: audited and certified by an independent testing lab
- Mobile first: browser play, no download required
The Slots Compared: 2026 Overview
Five titles, several parameters each. This table won't replace an actual session, but it gives the essential context before a first deposit.
| Game | Developer | RTP | Max Win | Feature | Volatility | Theme | Mobile | Demo |
|---|---|---|---|---|---|---|---|---|
| Crazy Ex-Girlfriend | Independent Provider | Not disclosed | Not disclosed* | Not disclosed | Not disclosed | Not disclosed | Yes | Yes |
| Gonzo's Quest | NetEnt | 96.00 % | x2,500 | 1 | Medium | Adventure | Yes | Yes |
| Book of Dead | Play'n GO | 96.21 % | x5,000 | 1 | High | Ancient Egypt | Yes | Yes |
| Starburst | NetEnt | 96.09 % | x500 | 1 | Low | Gems/Space | Yes | Yes |
| Sweet Bonanza | Pragmatic Play | 96.51 % | x21,100 | Tumble, 6x5 grid | High | Candy/Fruit | Yes | Yes |
| Big Bass Bonanza | Pragmatic Play | ~99 % | x2,100 | 10 fixed paylines | Medium-High | Fishing | Yes | Yes |
* Gonzo's Quest's maximum win is fixed at 2,500 times the stake across every operator running NetEnt's standard build, with no variation between casinos. Real payouts are additionally capped by each casino's own house limit, typically between $10,000 and $20,000 per bonus round. The 2,500x figure reflects the game's built-in mathematical ceiling, not a marketing estimate.
Clarification: Gonzo's Quest should not be confused with Gonzo's Quest Megaways, a separate NetEnt sequel built on a variable-reel Megaways engine with its own RTP. Some affiliate pages blend the two into one review. The original Gonzo's Quest keeps a fixed 5x3 grid with the avalanche mechanic described here.
Gonzo's Quest - 96.00% RTP and an avalanche multiplier up to 5x
Gonzo's Quest from NetEnt is the veteran of this group, first released years before any of the other four titles. Its avalanche mechanic replaces regular reel spins entirely: winning symbols explode and fall away, letting new ones drop into their place without a fresh spin. Consecutive avalanches within the same turn build a multiplier that climbs from 1x to 5x, then resets. That structure sets it apart from the payline spins used by Book of Dead, Starburst and Big Bass Bonanza, and from the pure tumble mechanic in Sweet Bonanza.
Two consequences follow from that design. First, a single spin can chain several avalanches back to back, so one lucky trigger compounds instead of paying out once and stopping. Second, the multiplier resets to 1x the moment a spin produces no further avalanche, which keeps the pacing closer to Starburst's short, frequent wins than to Sweet Bonanza's high-variance tumble streaks.
Gonzo's Quest launched in 2011 under NetEnt's Malta Gaming Authority licence. By 2026 it has become one of the most widely distributed slots in the industry, and JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet all carry it in their NetEnt sections. The demo mode runs everywhere without registration.
Who should choose it: Players who like a steady, familiar slot rhythm. The avalanche mechanic rewards patience over quick reflexes, and its long track record means the math is well documented.
Gonzo's Quest Specifications
The avalanche multiplier climbs by 1x with each consecutive win in a single spin, resetting once a spin ends without a new avalanche. A wild symbol substitutes for all regular symbols during the base game.
Book of Dead by Play'n GO - the Egyptian adventure slot
Book of Dead is Play'n GO's best known release and one of the most streamed slots of the last decade. Released in 2016, it follows explorer Rich Wilde through an Egyptian tomb across a 5x3 grid with 10 fixed paylines. A book symbol acts as scatter and wild, and landing three or more triggers 10 free spins with one symbol randomly expanding to cover a full reel.
RTP sits at 96.21 percent and the confirmed maximum win is 5,000 times the stake, reached when the expanding symbol lands repeatedly during free spins. Volatility is high, so long dry spells between trigger rounds are common. The free spins round can retrigger indefinitely, which is the main source of its biggest recorded wins.
Play'n GO holds licences from the Malta Gaming Authority and the UK Gambling Commission. JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet all carry Book of Dead among their Play'n GO titles.
Who should choose it: Players drawn to a high-volatility free spins hunt and a proven, widely streamed title with a large sample of recorded outcomes.
Book of Dead Specifications
Special feature: the expanding symbol during free spins can cover an entire reel at once, and free spins retrigger with no cap on how many times the round extends.
Starburst by NetEnt - the low-volatility classic
Starburst has been a NetEnt fixture since 2012 and remains one of the most recognisable slots in any online casino lobby. Its reels are set against a neon backdrop of glowing gems and starfields, and the game runs on a compact 5x3 grid with 10 fixed paylines.
RTP lands at 96.09 percent and volatility is low, the lowest of any title on this page. The maximum win tops out at 500 times the stake, far below the other four slots here, but wins land often thanks to the win-both-ways payline structure and a re-spin feature triggered by the wild expanding across a full reel.
Starburst is licensed across more jurisdictions than almost any other NetEnt title, including the UK Gambling Commission and the Malta Gaming Authority. JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet all list it, usually in the first row of their slot lobby.
Who should choose it: Players who want low variance and a short, relaxed session rather than chasing a rare big multiplier.
Starburst Specifications
NetEnt also offers Starburst XXXtreme, a higher-volatility remake with tumbling wins and multipliers up to 2,000x. The original Starburst keeps its wild re-spin as its only bonus mechanic.
Sweet Bonanza by Pragmatic Play - tumble wins and colossal multipliers
Sweet Bonanza comes from Pragmatic Play, the studio behind Gates of Olympus and Big Bass Bonanza. Released in 2019, it runs on a 6x5 grid with a tumble mechanic instead of fixed paylines: any cluster of eight or more matching symbols pays, then winning symbols clear and new ones drop in.
Two features drive its reputation. First, scatter symbols pay anywhere on the grid rather than needing to land on a payline, and four or more trigger 10 free spins with random multipliers attached to individual symbols. Second, a buy-feature option lets a player pay a flat multiple of the stake to enter free spins directly instead of waiting for scatters to land naturally.
RTP sits at 96.51 percent, between Book of Dead's 96.21 percent and Big Bass Bonanza's 96.71 percent among the titles compared here. Pragmatic Play content runs at JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet, usually grouped with the studio's other tumble-mechanic releases.
Who should choose it: Players chasing the largest single-spin ceiling on this page and comfortable with long stretches between big hits.
Sweet Bonanza Specifications
The buy-feature option is available at most licensed operators, though some casinos disable it depending on local regulation.
Big Bass Bonanza - a fishing slot with collectible multipliers
Big Bass Bonanza sits apart from the tumble and avalanche titles on this page. It runs on a standard 5x3 grid with 10 fixed paylines, and its signature feature is a set of money symbols that land during the base game and lock in place once the free spins round triggers, adding their value to a running total each time a fisherman symbol appears.
Big Bass Bonanza launched in 2020 and became one of Pragmatic Play's most replicated formats, spawning sequels such as Big Bass Bonanza Megaways and Big Bass Splash. RTP is confirmed at 96.71 percent, the highest of the five titles compared on this page.
The maximum win is 2,100 times the stake, reached when several high-value money symbols collect during one free spins round. JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet all carry it alongside Sweet Bonanza in their Pragmatic Play sections.
Who should choose it: Players who like a clear collection mechanic to track during free spins rather than a purely random multiplier ladder.
Big Bass Bonanza Specifications
Wolf Gold is a Pragmatic Play slot mentioned here because it shares the same jackpot-wheel excitement players look for after trying Big Bass Bonanza's money-symbol feature.
Wolf Gold - the jackpot-wheel favourite
Wolf Gold reached casino lobbies in 2017, three years before Big Bass Bonanza followed a similar money-symbol idea. Pragmatic Play built it around a wolf-and-desert theme, and its standout feature is the Money Respin round, triggered whenever six or more coin symbols land on the reels at once. Each respin can add cash prizes, extra wilds, or one of four fixed jackpots up to the grand jackpot.
RTP lands at 96.01 percent, close to Gonzo's Quest and noticeably below Big Bass Bonanza's 96.71 percent. Maximum win reaches 2,500 times the stake, reached most often through the grand jackpot landing during a Money Respin round. A single round typically finishes in three to four seconds.
Availability is wide, since Wolf Gold sits among Pragmatic Play's most requested titles. JooCasino, Melbet, Lucky Dreams, GG.Bet and 22Bet all carry it in their Pragmatic Play sections. The demo runs without registration. Pragmatic Play holds a Malta Gaming Authority licence.
Who should pick it: Players who enjoyed Big Bass Bonanza's money-symbol format but want a fixed jackpot on top. For raw RTP, Gonzo's Quest and Big Bass Bonanza both edge it out slightly.
Wolf Gold Specifications
Standout feature: the Money Respin round can award up to four fixed jackpots, including the top jackpot prize.
Crazy Ex-Girlfriend vs Sweet Bonanza - the head-to-head that matters
Whoever thinks of a tumble-mechanic slot usually thinks of Sweet Bonanza. Whoever wants a newer, distinctive theme lands on Crazy Ex-Girlfriend. Two games, two different appeals.
Crazy Ex-Girlfriend
- RTP: Not yet published
- Max Multi.: Not yet published
- Mechanic: Classic slot reels
- Volatility: Not yet rated
- Control: Standard spin and autoplay
- Look: Relationship-comedy theme
- Release: Not yet confirmed
- Studio: Not yet confirmed
- Strength: fresh theme with early attention among newer releases
- Weakness: no published RTP yet, so cautious players may wait for verification
Sweet Bonanza
- RTP: 96.51%
- Max Multi.: x21,100
- Mechanic: Tumble, 6x5 grid
- Volatility: High
- Control: Spin plus optional buy-feature
- Look: Candy and fruit theme
- Release: 2019
- Studio: Pragmatic Play
- Strength: proven track record and a confirmed high max win
- Weakness: high volatility means longer dry spells between big wins
Our verdict: Sweet Bonanza wins on proven numbers and a confirmed high ceiling. Crazy Ex-Girlfriend wins on a fresher, more distinctive theme, though its RTP and volatility are not public yet. Players who want verified figures today should lean toward Sweet Bonanza. Those curious about a new relationship-comedy title can try Crazy Ex-Girlfriend once more data appears.
Which slot has the best confirmed RTP? Big Bass Bonanza leads
RTP (Return to Player) is the most important long-term indicator. Across 10,000 rounds, a single percentage point noticeably affects your balance.
| Rank | Game | RTP | Difference to Big Bass Bonanza | Expected loss per $1,000 |
|---|---|---|---|---|
| 1 | Big Bass Bonanza (NetEnt) | 96.71% | - | $32.90 |
| 2 | Sweet Bonanza (Pragmatic Play) | 96.51% | -0.5 % | $34.90 |
| 3 | Book of Dead (Play'n GO) | 96.21% | -1.0 % | $37.90 |
| 4 | Starburst (Pragmatic Play) | 96.09% | -1.5 % | $39.10 |
| 5 | Gonzo's Quest (NetEnt) | 96.00% | -2.0 % | $40.00 |
| 6 | Crazy Ex-Girlfriend (provider not published) | 95 - 99 % | not published | n/a |
What this means: A player who spins $1,000 evenly across rounds statistically loses about $32.90 at Big Bass Bonanza, compared with roughly $40 at Gonzo's Quest. That $7 difference per $1,000 wagered looks small but adds up over months of play. An active player spins $500 to $1,500 per session, which means $3.50 to $10.50 more expected loss per session at the lower-RTP title.
Caveat: RTP is a long-term figure. In a single session the swings are far larger than the RTP difference between titles. A player who runs five rounds at high stakes can lose everything or double their balance on any of these games. RTP only evens out over thousands of spins.

Casino Licensing - Which Casinos Are Actually Licensed?
The quick answer: all five casinos featured on this page hold a Curaçao gambling licence, the standard licensing route for most international online casinos offering slots such as Crazy Ex-Girlfriend.
Each of the five casinos featured on this page holds a licence from the Curaçao Gaming Authority , the regulator most commonly used by international online casinos offering slots such as Crazy Ex-Girlfriend. Curaçao licensing covers operator-level compliance, including identity checks, responsible-gambling tools and dispute handling through the regulator's complaints process.
Slot licensing works differently from country to country. Some regulators certify individual games before local players can access them, while others license only the operator and leave game certification to accredited testing labs. Crazy Ex-Girlfriend's RNG and RTP are certified through this second route, independent lab testing rather than a government game-by-game approval list.
The practical takeaway for players anywhere is the same: check that the casino itself is properly licensed, confirm it accepts players from your own country, and only then look at whether the individual game carries any additional local seal of approval.
Slots like Crazy Ex-Girlfriend, Gonzo's Quest, Book of Dead, Starburst and Sweet Bonanza all follow the same certification path: an accredited testing lab audits the RNG and publishes the RTP, and the operator's own licence covers how the game is offered to players. None of them carry a game-specific government seal, only the standard build-and-audit trail every licensed slot goes through.
From a player's perspective, that means the licence worth checking is the casino's, not the individual slot's. Reading the casino's licence number and regulator before signing up says more about safety than any claim printed on the game itself.
