Overview
Released by PG Soft on September 2, 2021, Jurassic Kingdom runs on the studio's "Colossal Reels" engine, the same dynamic multiway format behind Anubis Wrath, generating up to 46,656 ways to win from a 6-reel grid that expands and contracts every spin.
A dinosaur/jungle theme built around a smoking volcano backdrop, with colorful prehistoric creatures and jungle foliage framing the reels.
Bonus Features Breakdown
Colossal Reels & Cascading Wins
Each of the 6 reels displays between 2 and 6 symbols on every spin, changing the total number of ways to win from one spin to the next - up to a maximum of 46,656 when every reel is fully expanded. Winning symbols cascade away and new ones drop in, potentially chaining into further wins on the same spin.
Wild & Wilds-on-the-Way
The Wild substitutes for all paying symbols and appears on reels 2 through 5. Silver-framed symbols on the board can transform into a matching symbol on the next cascade, while gold-framed symbols instead transform into a Wild - turning a dead-looking board into a live one before the next drop.
Progressive Multiplier
A multiplier starts at 1x and climbs by 1x with every cascading round, capping at 5x. It applies to whatever win is on the board at the time, making a long cascade chain worth meaningfully more than a single isolated win.
Scatter & Free Spins
Landing four or more scatter symbols in the same cascading sequence triggers 8 Free Spins, with 2 additional spins awarded per scatter beyond the fourth. Extra "+1 free spin" symbols can appear during the round to extend it further.
Buy Feature
Where permitted by local regulations, players can pay 75x their stake to buy directly into Free Spins - not available in the UK and, per some casino integrations, not offered in the game's free-play demo either.
Betting Range & Jackpot
Total bets run from $0.20 up to $20 per spin. Jurassic Kingdom doesn't carry a jackpot round - its biggest realistic win comes from the progressive multiplier stacking across cascades during Free Spins, with independent simulation putting it at 6,684x your total stake.
RTP & Volatility
RTP: 96.72%. Volatility: Medium.
Our Take
Wilds-on-the-Way is a genuinely clever piece of design - rather than a cascade just clearing dead symbols and hoping for the best, silver- and gold-framed symbols on the board actively transform into matching symbols or fresh Wilds before the next drop, giving you visible information about what's about to improve before it happens rather than pure chance.
Medium volatility is the other thing that sets this apart from most of the dinosaur-themed and cascading titles on this site, which lean high volatility almost across the board. That makes Jurassic Kingdom a noticeably more forgiving session to session, even though the 5x multiplier cap is modest next to titles that let multipliers climb into the hundreds or thousands.
Worth knowing before you chase a big number here: PG Soft's own marketing cites a 100,000x max win for this game, but SlotCatalog's independent analysis - based on a billion-spin simulation - puts the realistic figure at 6,684x, and none of our other sources even mention the higher number. We've used the simulated, defensible figure rather than the advertised one.
At 6,684x, the real ceiling lands close to PG Soft's own Anubis Wrath and a handful of other titles in the site's mid-to-upper tier - solid rather than exceptional, and the honest headline here is the cascade mechanic's design quality rather than a standout jackpot number.
Pros & Cons
What We Liked
- Wilds-on-the-Way mechanic gives cascades a visible, informative build-up rather than just clearing and hoping
- Medium volatility is more forgiving session to session than most comparable titles on this site
- 96.72% RTP is solidly above average and consistently confirmed across all our sources
- Colossal Reels engine (up to 46,656 ways) gives every spin a lot of surface area for wins
Where It Falls Short
- 5x multiplier cap is modest next to titles that let multipliers climb far higher
- PG Soft's own marketing advertises a 100,000x max win that independent simulation shows is unrealistic - the real figure is 6,684x
- Buy Feature isn't available in the UK, and some casino integrations don't offer it in demo mode either
- No progressive jackpot - the realistic ceiling is fixed regardless of how long the game's been played
