The problem with Raging Rex 2 is not the slot itself – the Rampage Respins with Rex walking across the grid and hatchlings locking in sync deliver exactly the momentum-based session that 4,096-way slots are built for. The problem is that after enough sessions, you know the exact rhythm: Rex lands, walks left, hatchlings tag along, wins collect at the end. The best slots like Raging Rex 2 that break that predictability while keeping the walking wild core are Raging Rex 3, Merlin’s Grimoire, and Blazin Bullfrog. Each preserves the expanding or walking wild mechanic but reshapes the session around different volatility profiles, grid formats, and bonus structures.
Top picks for slots like Raging Rex 2 are: Raging Rex 3, Merlin’s Grimoire, and Blazin Bullfrog. Original provider: Play’n GO. RTP: 96.20% (Varies). Volatility: Medium (6/10).

The mechanics that define Raging Rex 2
Raging Rex 2 plays on a 6×4 grid with 4,096 ways to win. The centrepiece is the Rampage Respins feature, triggered when a fully stacked 1×4 Rex wild lands on reels 2 through 6. Rex locks in place and walks one reel left per respin, collecting wins at each step until he exits the grid. Hatchling wilds (1×1 symbols) also lock and walk in sync with Rex, adding coverage across multiple reels simultaneously. Three free spin modes offer distinct strategies. Primal Fury awards 8 to 20 spins where Rex is sticky and walks in any direction but hatchlings leave after one spin. Hatchling Mania delivers 7 to 13 spins where hatchlings are sticky with 2x or 3x multipliers but Rex does not appear. Jurassic Mayhem combines both – 5 to 11 spins where all wilds are sticky and move freely. The volatility is medium at 6/10, the max win is 30,000x, and the RTP sits at 96.20% at the top tier.

Raging Rex 3
Raging Rex 3 keeps the same 6×4 grid and 4,096 ways that define its predecessor, so the transition feels seamless. The Rampage Respin mechanic returns with Rex walking across the reels, but the sequel pushes volatility from 6/10 to 8/10 and raises the max win from 30,000x to 40,000x. Enhanced bonus features add new wild behaviours and multiplier mechanics that create sharper peaks during free spins. At €10 / £10 / $10 stake, that 40,000x ceiling represents €400,000 / £400,000 / $400,000. The trade-off is a drier base game – the higher volatility means longer gaps between Rampage triggers compared to the medium-variance pacing of Raging Rex 2.
Merlin’s Grimoire
Merlin’s Grimoire starts on a 5×3 grid with 243 ways but expands up to 5×6 with 7,776 ways during its Grimoire Spins feature, where each cascading win adds rows to the grid. The expanding mechanic creates a similar momentum loop to Raging Rex 2’s walking wilds – once the feature triggers, wins compound as the grid grows. The 31,104x max win nearly matches Raging Rex 2’s 30,000x ceiling. Very high volatility at 10/10 means sessions play rougher than Raging Rex 2’s medium variance, with longer stretches between feature triggers but sharper payouts when they hit. The magic theme is a complete departure from dinosaurs, but the underlying maths share the same progression-based DNA.
Blazin Bullfrog
Blazin Bullfrog uses an expanding grid mechanic where the playing area grows during bonus features, adding rows and reels to increase the number of active paylines. Sticky wilds lock in during the expansion, creating coverage across the growing grid that mirrors how Rex and hatchlings spread across reels during Rampage Respins. The 20,000x max win sits below Raging Rex 2’s 30,000x but the high volatility (8/10) produces sharper individual spikes. The amphibian theme offers a lighter visual tone while the underlying wild-expansion mechanic preserves the mechanical satisfaction of watching symbols lock and spread across an active grid.
Coils of Cash
Coils of Cash runs on a 5×3 grid with 20 paylines and builds around snake wilds that expand across reels when they form part of a winning combination – a direct parallel to Rex expanding to fill a full reel before walking. The respin mechanic triggers when expanding wilds land, creating consecutive win opportunities as the snake moves position. High volatility at 8/10 produces more aggressive session swings than Raging Rex 2’s medium profile. The 10,000x max win is the main compromise, sitting at one-third of Raging Rex 2’s ceiling, which limits upside but keeps the expanding wild satisfaction intact.
Golden Osiris
Golden Osiris uses a 5×5 grid where symbols expand to fill adjacent positions during cascading win sequences, creating spreading coverage that resembles how hatchling wilds lock around Rex during Rampage Respins. The expanding symbol mechanic triggers cascades that build through progressive multipliers, adding momentum to each spin sequence. High volatility at 8/10 pushes sessions closer to Raging Rex 3’s pace than Raging Rex 2’s medium profile. The 10,000x max win is significantly lower than Raging Rex 2’s 30,000x, but the cascading expansion mechanic makes the base game more consistently interactive.
At €10 / £10 / $10 stake, Raging Rex 2’s 30,000x max win would return €300,000 / £300,000 / $300,000.
If the Rampage Respins feel predictable, start here
If Rex’s left-to-right walk feels too linear and you want multidirectional wild movement, Raging Rex 3 lets wilds move in any direction during free spins. If the medium volatility produces sessions that feel flat without enough peaks, Merlin’s Grimoire jumps to 10/10 volatility with a grid that literally grows as wins cascade. If you enjoy the sticky wild coverage but want a different visual and structural format, Blazin Bullfrog expands the grid itself rather than walking wilds across a fixed one. And if the 4,096 ways format occasionally feels too spread out and you want tighter win concentration, Coils of Cash narrows to 20 paylines where expanding wilds have more immediate impact per symbol position.

Slots like Raging Rex 2 questions
What slot is most similar to Raging Rex 2?
Raging Rex 3 is the closest match. It uses the same 6×4 grid with 4,096 ways to win, the same Rampage Respin mechanic with walking Rex wilds, and the same three-option free spin structure. The main differences are higher volatility at 8/10 versus 6/10, an increased max win of 40,000x versus 30,000x, and enhanced wild behaviours during bonus rounds.
Are there slots with walking wilds like Raging Rex 2?
Several Play’n GO slots use walking wild mechanics. HammerFall features Templar walking wilds in its free spins round. Coils of Cash has snake wilds that expand and shift position during respins. The original Raging Rex also uses the same walking Rex mechanic with high volatility at 8/10 and a 5,000x max win on the same 6×4, 4,096-way grid.
Is Raging Rex 2 high volatility?
Raging Rex 2 is rated medium volatility at 6/10 on Play’n GO’s internal scale, which is lower than the original Raging Rex at 8/10 and Raging Rex 3 at 8/10. Medium volatility means more frequent base game wins but smaller individual payouts compared to its higher-variance sequels. The 30,000x max win remains substantial despite the medium variance profile.
Can I play slots like Raging Rex 2 for free?
Most Play’n GO titles including all of these alternatives are available in free demo mode at casinos that stock them. Demo availability depends on your region and the specific casino operator, as some jurisdictions restrict access to free play. Testing the demo is the fastest way to compare how walking wilds, expanding grids, and cascading mechanics differ between titles.
Raging Rex 3 is the obvious starting point for fans who want the same loop with higher stakes and sharper peaks. Merlin’s Grimoire is the pick when you want the progression mechanic in a completely different theme and volatility tier. Blazin Bullfrog splits the difference with sticky wilds on an expanding grid that captures the spreading coverage of Rampage Respins without the dinosaur aesthetic. Coils of Cash and Golden Osiris work as shorter-session alternatives when the 4,096-way format feels like overkill and you want tighter win concentration from expanding wilds.
