Overview
Reviewed by Slotland Entertainment's CryptoSlots brand in December 2024, in its higher-stakes "High Limit" configuration.

Bonus Features Breakdown
T-Rex Expanding Wild
The T-Rex acts as the wild, substituting for regular symbols. During certain Free Spins configurations, it upgrades to an Expanding Wild that fills its entire reel when it lands.
Raptor Scatter & Pick-a-Spins Free Games
Landing 3, 4, or 5 raptor scatter symbols determines which Wild tier the Free Spins round uses - 3 scatters plays without Wilds, 4 adds regular Wilds, and 5 adds Expanding Wilds. Whichever tier triggers, a Pick Me mini-game then reveals your actual spin count: three raptors hide 5, 10, or 15 Free Spins, and you choose one.
Shifting Reels, Sticky Wins & Escalating Multiplier
During Free Spins, any winning payline's symbols stay sticky for an extra round, and the leftmost reel drops out as the remaining reels shift left. Each winning round also raises a multiplier by one level, up to 5x - a non-winning round resets it back to 1x.
Devour Bonus
A random symbol transformation that can trigger on a non-winning spin, swapping a symbol on the board to potentially turn a loss into a paying combination.
Betting Range & Jackpot
Total bets run from $20 up to $480 per spin. Lost World doesn't carry a jackpot round - its biggest built-in win comes from the escalating Free Spins multiplier and Shifting Reels mechanic, capped at 2,500x your payline bet.
RTP & Volatility

Our Take
The most distinctive thing about Lost World's Free Spins isn't the spin count - it's that landing more scatters doesn't hand you more spins directly, it upgrades which Wild tier you're playing with. Three scatters means no Wilds during the round at all, four adds regular Wilds, and five upgrades to Expanding Wilds - the actual number of spins is instead chosen by the player in a separate Pick Me game, regardless of which tier triggered it. That's a genuinely unusual way to structure a scatter trigger, and it means a lucky 3-scatter hit that also picks 15 spins can still be a modest round if it plays out without any Wilds at all.
Shifting Reels is what actually changes the feel of the bonus round - sticky winning symbols combined with the leftmost reel dropping out each round means a strong payline has a genuine chance to repeat, and the multiplier climbing to 5x on consecutive wins (before resetting hard back to 1x on a miss) makes every Free Spins round feel streaky in a way that rewards a hot run disproportionately.
The Devour Bonus is a smaller but likeable touch - a random symbol swap that can only help, since it only has a chance to trigger on spins that would otherwise pay nothing. It won't change the game's underlying math in any meaningful way, but it's the kind of small mercy that makes a dry stretch feel less punishing.
Worth being upfront about: the only bet range we could confirm comes from CryptoSlots' own review of the "High Limit" configuration specifically ($20-$480 per spin), which is considerably higher-stakes than most other Slotland Entertainment titles on this site. We don't have a confirmed range for a standard, lower-stakes version, if one exists - and as with the rest of this catalogue, Slotland Entertainment doesn't publish an RTP or volatility rating for this title.
Pros & Cons
What We Liked
- Free Spins Wild tier and spin count are determined separately, giving the bonus round a genuinely different shape depending on both your scatter count and your Pick Me choice
- Shifting Reels combined with sticky wins and an escalating multiplier rewards a hot Free Spins run disproportionately
- Devour Bonus adds a small, purely upside random-transformation chance on otherwise losing spins
- Distinctive Jurassic art direction with a well-realized dinosaur symbol set
Where It Falls Short
- No published RTP or volatility rating
- The only confirmed bet range is from the higher-stakes "High Limit" configuration ($20-$480) - not accessible to small-stakes players the way most other Slotland Entertainment titles are
- Multiplier resets fully to 1x on a single non-winning round during Free Spins, so a cold spin can undo several rounds of build-up at once
- 2,500x max win is modest next to some of the higher-ceiling titles in this catalogue
