Jumanji slot review

About the Jumanji slot

NetEnt, the Stockholm studio founded in 1996 and owned by Evolution since December 2020, made Jumanji as a licensed game based on the film. Released in 2018, the game is approachable: low volatility, a modest number of paylines and four random features that can liven up ordinary spins.

It sits in our TV and film slots collection and is a useful contrast to the high-variance games that dominate many new releases. For other reviews in the same format, start at our slots hub.

The 3-4-5-4-3 layout and 36 paylines

Most video slots use a flat 5×3 rectangle. Jumanji's reels grow towards the centre: three positions on reel 1, four on reel 2, five on reel 3, then back to four and three. That gives 3 + 4 + 5 + 4 + 3 = 19 symbol positions, against 15 on a standard grid, arranged roughly like a diamond.

Wins pay along 36 fixed paylines that trace routes through this shape. The bigger middle reel means the centre of the grid matters most: a wild on reel 3 can sit on more lines than a wild on reel 1. The paytable diagrams show exactly which positions each line uses.

How the features work in the Jumanji slot

Instead of one headline feature, Jumanji spreads its excitement across four random modifiers. Any base-game spin can trigger one of them without special symbols.

Each one helps in a different way. Sticky Vines works like a respin that holds what already paid. Monsoon Wilds fills whole reels with wilds, which on a 36-line game can connect many lines at once. Monkey Mayhem is the most direct, because it rearranges the grid so that the spin produces a win. Wild Stampede scatters extra wilds across the board.

The bonus and its free spins rounds

Three or more scatter symbols start the bonus. In it, you can reach free spins rounds based on the same four features, so the modifiers you see in the base game reappear in a stronger, repeated form. Our checked data does not give spin counts or multipliers for those rounds, so read the game's help screen for the details at your casino rather than relying on outside summaries.

Jumanji RTP and low volatility on a £20 budget

At the default 96.33% the house edge is 3.67%, so each spin costs on average 3.67% of the stake. A casino may run a lower RTP version, so the help screen figure is the one to trust.

Low volatility means wins tend to be smaller and more frequent, so results usually stay closer to the average over a few hundred spins than on a high-variance game. That makes Jumanji a reasonable choice if your aim is a longer session on a fixed budget. A worked example: at 20p a spin, 400 spins puts £80 through the game and the average cost is about £2.94. Results on a low-volatility game tend to sit closer to that figure than on a swingy slot, but it can still lose the whole £20; low volatility narrows the swings, it does not remove the edge.

Frequent small wins can be misleading. Under UK rules a game must not celebrate a return that is less than or equal to your stake, so a 10p return on a 20p spin should appear without fanfare. Watch the net position on screen rather than the number of wins.

6. Check the net spend display and stop when your limit is reached.

Common Jumanji slot misconceptions

• "Random features mean the game is generous." The features are paid for out of the 96.33% RTP; they redistribute the return rather than add to it.
• "A feature is due after a quiet run." Each spin is independent, as our page on whether online slots have memory explains.
• "Low volatility means losses stay small." Over enough spins the house edge still takes its share; low volatility only slows the swings.
• "Branded slots pay less because of the licence." The published RTP is what counts, and Jumanji's default figure is in the normal range for modern slots.

UK rules: what you will see when playing Jumanji

Every online slot in Great Britain follows the same design standard. The Commission's RTS 14 responsible product design rules (opens in a new tab) require at least 2.5 seconds per spin, ban autoplay, turbo and slam-stop, and stop celebrations of returns at or below the stake. Since 17 January 2025 your net spend and time played are shown throughout. Stakes are capped at £5 for players aged 25 and over and at £2 for 18 to 24-year-olds, the second limit announced in the government's notice on the £2 maximum stake (opens in a new tab). See our game design rules page for the full list.

Low-volatility alternatives to Jumanji

If Jumanji's gentle pace suits you, NetEnt has several calmer games. Starburst is the classic low-volatility pick with a 96.09% RTP and a 500x top win. Blood Suckers is low volatility with a 98% RTP. Finn and the Swirly Spin and Butterfly Staxx sit at low to medium. For another film licence, try Blueprint's The Goonies.
