Beast Mode takes you back to late 80s LA. Muscle Beach vibes. Neon colors. Anthropomorphic animals pumping iron. This is the second collaboration between Relax Gaming and CasinoGrounds after Iron Bank, and they went full retro with it.
I wanted to check this out because the first collab was excellent. Beast Mode keeps that creative energy but switches to a completely different theme. Three bonus options to choose from. Cascading wins. Mystery symbols. A 500x multiplier ladder. And those feel-good synthwave sounds.
Here's what I found.

How It Looks
Pure 80s nostalgia. Pastel colors. Neon lights. Venice Beach setting with palm trees and that golden hour glow.
The characters are anthropomorphic animals. Lions, dogs, other beasts all jacked up and ready to lift. Using animals instead of humans was smart. Keeps it playful instead of coming off like a Pain & Gain slot.
The soundtrack is synthwave perfection. Retro beats that make you want to rollerblade along Santa Monica. Small details like how symbols slice off the reels when they win add to the satisfaction.
Base Game
6 reels, 4 rows, 4,096 ways to win. Match at least 3 symbols from left to right.
Cascading wins mean winning symbols get removed and new ones drop in. Keeps going until no new wins form.
Low symbols: Graffiti style 10 through A (1x for six of a kind)
Premium symbols: Kettlebells, roller skates, dumbbells, ghetto blasters, and lions (2.5x to 25x for six of a kind)
Wild: Bling necklace wild on reels 2 through 6. Substitutes for everything and contributes to bonus features.
Random Mystery Spin
Can trigger randomly during base game.
At least 1 mystery symbol is guaranteed to land. Mystery symbols reveal the same symbol type. They stay on the reels for the next cascade and change to a new symbol type.
This continues as long as you keep winning. Excluding wins from mystery symbols alone.
Adds some base game excitement between bonus triggers.
Free Spins Trigger
Collect 3 or 4 bonus symbols during a cascade sequence.
With 3 scatters: You can gamble for upgraded free spins. 50/50 odds on a wheel spin. Land on skull and you lose the feature entirely.
With 4 scatters: Upgraded free spins automatically. No gamble needed.
The gamble is risky. I've lost free spins multiple times going for upgrades. Use it carefully or skip it entirely.
Three Bonus Options
After triggering, you choose one of three bonus games. Each plays differently.
Mystery Symbols Free Spins
Starts with 6 spins (10 when upgraded).
Mystery symbols drop to the lowest available position and stay for the whole feature. They reveal the same random symbol each cascade or spin.
Bomb symbols: Expand the four middle reels by +1 row. Up to 7 rows max. Also awards +3 spins.
At full expansion you have more ways to win with sticky mystery symbols filling positions.
Multiplier Ladder Free Spins
Starts with 8 spins (9 when upgraded) and a 1x multiplier.
After every win or between spins, the multiplier climbs to the next value on the ladder. Certain ladder positions award extra spins.
Maximum multiplier: 500x
This is where the big potential lives. Climbing that ladder while wins keep coming can explode fast.
Expanding Wild Free Spins
Starts with 7 spins and a 1x multiplier (10x when upgraded).
Wilds expand downward when they land. Each wild in view adds +1 to the global win multiplier.
Stack wilds across multiple reels with a growing multiplier and things get interesting.
Bonus Buy
80x your bet to skip straight to the free spins selection screen.
The RTP jumps to 97% when buying. That's one of the better bonus buy RTPs available.
You still choose which of the three features you want. Good value at 80x.
If you like bonus buy slots, this is a solid option.
Extra Spins
During all bonus modes, landing +1, +2, or +3 Spins symbols adds that many free spins to your count.
Helps extend features when the main mechanic is working.
My Experience
I've played all three bonus options plenty of times.
Mystery Symbols is consistent. Sticky symbols filling the grid with expanding rows creates steady wins.
Multiplier Ladder is the high risk high reward option. Climbing toward 500x feels amazing when it happens. But you can also stall at low multipliers.
Expanding Wilds is somewhere in between. The upgraded 10x starting multiplier makes a big difference.
No clear winner between them. Depends on your mood and risk tolerance.
Bankroll Advice
High volatility with 25,000x max win.
Bring at least 250 to 300x your bet. At €1 spins, that's €250 to €300 minimum.
The 80x bonus buy is affordable. The 97% RTP on bonus buy makes it tempting to skip base game entirely.
Watch out for the gamble feature. Losing free spins hurts.
Mobile
Works great on mobile. The bright neon visuals pop on any screen. Cascading wins run smoothly. Bonus selection is easy to navigate.
Who Should Play This
Beast Mode works for you if:
- You like 80s retro themes
- Multiple bonus options appeal to you
- Cascading wins with mystery symbols sound fun
- A 500x multiplier ladder excites you
- Relax Gaming and CasinoGrounds collabs interest you
- 25,000x max win is enough
Skip this if:
- 80s aesthetic isn't your style
- You prefer one clear bonus feature
- The gamble mechanic feels too risky
- You need higher max win potential
- €40 max bet is too limiting
What I Liked

- 97% RTP on bonus buy is excellent
- Three distinct bonus options
- 500x multiplier ladder
- Synthwave soundtrack is perfect
- Visuals are creative and fun
- 80x bonus buy is affordable
- Cascading wins keep action flowing
- Mystery symbols mechanic works well
What I Didn't Like
- 90% RTP version exists (check your casino)
- Gamble feature can cost you free spins
- €40 max bet limits high rollers
- No clear best bonus option
- Base game can drag between features
Final Verdict
Beast Mode is a better game than Iron Bank in my opinion. More personality. Better vibes. Three solid bonus options instead of one complex feature.
The 80s Venice Beach setting works perfectly. Jacked up animals, neon colors, synthwave music. It's weird but in the best way.
Having three bonus choices means you can experiment. Mystery Symbols for consistency. Multiplier Ladder for max potential. Expanding Wilds for a balance.
The 97% bonus buy RTP is one of the best around. At 80x cost, it's reasonable too. The gamble feature adds risk if you want it.
Worth playing if you like creative themes and want variety in your bonus options. Relax Gaming and CasinoGrounds made something special here.
My Rating: 4/5
Creative theme, excellent bonus buy RTP, fun bonus variety. The €40 max bet and risky gamble feature keep it from perfect. Best for players who appreciate unique aesthetics and multiple feature options.
