Jumanji slot review

About the Jumanji slot from NetEnt

Jumanji is a branded slot built on the Jumanji films, released in 2018 by NetEnt. NetEnt was founded in Stockholm in 1996 and has been part of Evolution since December 2020. Its best-known games include Starburst, Gonzo’s Quest and Mega Fortune, and Jumanji belongs to the run of licensed titles it made in the late 2010s, alongside Narcos and Vikings.

What sets it apart is the shape of the reels. Instead of a rectangle, the grid widens towards the middle: 3 rows on reel 1, 4 on reel 2, 5 on reel 3, then back to 4 and 3. That is 19 symbol positions in total, covered by 36 paylines.

“Default” means 96.33% is the standard setting; a casino may run another version. The RTP in the game’s help screen is the one that applies to you.

How the features work: Jumanji’s four random base-game features

Any base-game spin can trigger one of four features at random. You don’t need special symbols for them, and you can’t influence which one appears. The outcome is set by the game’s random number generator, which licensed games must use under the Commission’s standard on random outcomes (opens in a new tab).

Sticky Vines

Winning symbols and any wilds stick in place, and the other positions respin. It gives a win a second chance to grow before the spin is settled.

Monsoon Wilds

One or two whole reels turn wild. On a grid where the middle reel holds five symbols, a fully wild reel covers a lot of the screen.

Monkey Mayhem

The symbols on screen are reshuffled so that a win is formed. It always produces a win, but the size of that win is not set by you.

Wild Stampede

Up to nine wilds are placed on random positions across the reels, which can link up several of the 36 paylines at once.

The Jumanji bonus and its free spins

Three or more scatter symbols trigger the bonus. Rather than a single free spins round, it offers free spins rounds built around the same four features you see in the base game, so the vines, the monsoon, the monkeys and the stampede each get a bonus-round version. Casinos.com’s Jumanji page (opens in a new tab) lists the same feature set.

The verified details stop there, so we won’t guess at spin counts or multipliers for each round. The game’s help screen sets out exactly how each bonus version plays, and it is worth reading before you start, because the rounds differ.

Jumanji slot RTP and low volatility explained

At the default 96.33% RTP, the house edge is 3.67%. That is the average share of each pound staked that the game keeps over a very large number of spins. Over a short session, results can land anywhere.

Low volatility means wins tend to come more often but in smaller amounts. Four random features in the base game help with that, because they add wins between scatter bonuses. The trade-off is a lower ceiling: low-volatility games rarely produce very large single wins.

The verified specifications don’t include a max win figure for Jumanji. If the top prize matters to you, open the paytable in your app, where the game sets out its limits.

What the Jumanji slot costs at 10p, 50p and £1

Average cost = total staked × house edge. At 3.67%, £20 staked costs about 73p on average. But a session’s total staked is usually more than your budget, because small wins are staked again. The table shows how quickly turnover builds.

A low-volatility game suits a small budget better than most, because frequent small wins keep the balance moving. That doesn’t change the maths: the longer you play, the more you stake, and the house edge applies to every pound of it.

Playing the Jumanji slot on a phone

The diamond-shaped grid is narrower at the edges than a standard 5 × 4 slot, which helps on a phone screen. The specifications we verified don’t say whether the game offers a portrait mode, so try rotating to landscape if the middle reel feels squeezed.

1. Sign in to a UK-licensed casino app whose age and ID checks you have already completed.
2. Search the game lobby for “Jumanji” and check the developer is NetEnt.
3. Tap the info or help icon and check the RTP and the description of each bonus round.
4. Choose your stake, then start each spin yourself, since UK apps don’t offer autoplay.
5. Set a reality check reminder in your account if you want a prompt after a set time.

Random features add animations, so a spin can take a little longer when one fires. If your signal drops mid-spin, the Commission’s rules on interrupted gambling (opens in a new tab) set out what operators must do. Our answer on losing signal during a spin covers the practical side.

How UK rules apply to Jumanji in casino apps

Jumanji was released before the Commission’s 2021 slot design changes, so UK versions follow the updated rules. The Commission’s package of changes to make online games safer (opens in a new tab) set the baseline.

Jumanji slot review verdict

Jumanji is a sensible pick for players who want regular action from a modest budget and like features that can appear on any spin. It is less suited to anyone after a high-volatility chase or a large published max win.

Slots like Jumanji

If you like film or TV branding, NetEnt’s other licensed games are the obvious next step. If it is the random features you enjoy, try a slot with a strong base-game mechanic.

Where to play Jumanji-style slots with a welcome offer

We don’t have an offer linked to Jumanji and can’t confirm which partner apps stock it, so check the lobby before joining. The welcome offers here are for selected slots. 18+ and terms apply to all three.

• PlayOJO: a first deposit of £10 or more gets new UK customers (excluding Northern Ireland) 80 free spins on Big Bass Bonanza at 10p a spin. Winnings have no wagering and are paid as cash. The offer is only available through the designated link and can’t be combined with others.
• Coral: new players who deposit and bet £10 or more on slots from 1 October 2026 to 1 February 2027 get 100 free spins on selected games at 10p each. Accept within 48 hours; the spins are valid for 7 days, with no wagering on winnings. Qualifying deposits can’t be made by Neteller, PayPal, Paysafe, Skrill, prepaid card or certain debit cards.
• Ladbrokes: new customers who deposit and spend £10+ on slots get 50 free spins each day for their first 10 days, capped at 500, at 10p on selected games. Each day’s spins must be claimed before 23:59 and used within 7 days, with no wagering. If you fund the account by prepaid card, PayPal, Paysafe, Neteller, Skrill or Moneybookers, the offer doesn’t apply.

That is £8, £10 and up to £50 of spins at face value. Coral and Ladbrokes share an operator, LC International Limited (Entain), so one person may not be able to open new accounts with both. Spin offers don’t remove the house edge.

18+. Every casino game has a built-in house edge, so over time you should expect to lose what you stake. Set a budget before you play and stop when it’s gone: safer gambling tools and support. Free, confidential help: National Gambling Helpline 0808 8020 133.
