Big Atlantis Frenzy launched on June 9, 2022 and it's arguably the most original BGaming slot from a game-design standpoint. Why? At the start of every session, you choose your grid from 3 distinct options: 5x3 (5 paylines), 5x4 (10 paylines), or 5x5 (20 paylines). That's unique in the market — most slots lock you into a single fixed format. This flexibility changes the minimum stake, the perceived variance, and your odds of hitting combinations.
This is a full Big Atlantis Frenzy review: why the 3-grid selection changes the experience, what the Fisherman Wilds that collect Fish symbols are really worth, the official 96.7% RTP, the highly accessible 50x bonus buy, and where to play.
TL;DR — Big Atlantis Frenzy in 4 points
- BGaming slot, June 2022, a polished fishing/Atlantis treasure-hunt theme. Choice of 3 grids: 5x3 / 5x4 / 5x5. RTP 96.7%.
- Medium-high volatility that varies with the grid you pick. Max win 4,320x — modest, but consistent with the multi-grid design.
- Signature mechanics: Boat Scatters trigger 10/15/20 free spins, Fisherman Wilds automatically collect Fish symbols, multipliers up to x10 during FS, and a Chance x3 feature (+50% stake) that triples your bonus odds.
- Highly accessible 50x-stake bonus buy (one of the lowest at BGaming). Wide betting range: min €0.10 / max €100. Top 5 spots: SpinAura, BetRiviera, HunnyPlay, BigClash, Betti.
The 3-grid selection — why it's unique
Here's how it works:
| Grid | Paylines | Min stake | Variance | Best for |
|---|---|---|---|---|
| 5x3 | 5 paylines | Lowest | Lower | Modest bankrolls, longer sessions |
| 5x4 | 10 paylines | Mid-range | Medium | A balanced compromise |
| 5x5 | 20 paylines | Highest | Higher | Chasing the 4,320x max win |
No other BGaming slot offers this level of flexibility. Most slots force a fixed format — Big Atlantis Frenzy lets you pick your variance before each session. It's the slot's signature design argument.
Practical takeaway: you can adjust your stake and variance to match your bankroll of the moment without switching slots. Modest bankroll? Play 5x3 at €0.10. Feeling a big win coming? Switch to 5x5 at €1.
Fisherman Wilds — the core mechanic
During Free Spins:
- You trigger the FS via Boat Scatters:
- 3 scatters = 10 spins
- 4 scatters = 15 spins
- 5 scatters = 20 spins
- During the FS, Fisherman Wilds land on the grid
- Fisherman Wilds automatically collect every Fish symbol on the grid
- The more Fish you collect, the higher the global multiplier climbs (up to x10)
- Overlapping combinations with a x10 multiplier are the path to the 4,320x max win
It's a visually satisfying mechanic (a little fisherman animation scoops everything up) that defines the slot.
Chance x3 — a unique feature
Chance x3 is a variation on BGaming's classic Chance x2:
- Cost: +50% stake
- Effect: triples your bonus odds (vs. doubling on the standard Chance x2)
- RTP: broadly neutral (offset by the +50% stake)
Verdict: yes, worth it if you're aiming for a natural bonus. Tripling your bonus odds for +50% stake remains mathematically attractive. Turn it off if you're playing a long base-game session.
Bonus buy — 50x stake (one of the most accessible)
| Criterion | Value |
|---|---|
| Cost | 50x stake |
| At €0.10 | €5 per buy |
| At €0.30 | €15 per buy |
| At €1 | €50 per buy |
| Guarantees | Free Spins triggered |
| Multipliers | Random (Fisherman Wilds collect Fish) |
Bonus buy is banned in the UK. 50x stake is one of the most accessible tiers at BGaming (vs. 100x on Wild Cash X9990 and Aztec Magic Megaways). Excellent cost-to-EV ratio.
Official RTP — 96.7%
| Criterion | Value |
|---|---|
| Base RTP | 96.7% |
| Volatility | Medium-High |
| Hitting the max win | Rare (cap 4,320x) |

Strategies by budget
Small budget (< €200)
Pick the 5x3 grid (5 paylines, lowest min stake) and turn on Chance x3 to triple your bonus odds. At €0.10 base → €0.15 effective, you can run 1,300+ boosted spins. Alternative: 20 buys of 50x at €0.20 (= €10/buy).
Medium budget (€500-1,000)
Pick the 5x4 grid (a balanced compromise) and stake €0.30-€1. The 50x buy at €0.50 (= €25/buy) stays affordable. Recommended mix: 70% buys of 50x + 30% boosted spins with Chance x3.
Large budget (€2,000+)
Pick the 5x5 grid to chase the 4,320x max win. Stakes of €2-€5 are justifiable. At the €100 max bet, you could theoretically aim for a €432,000 jackpot — but the slot remains modest compared with rival Megaways. For large bankrolls chasing the biggest wins, prefer Aztec Magic Megaways (12,960x) or a Pragmatic Megaways title.
