Big Atlantis Frenzy Overview
Big Atlantis Frenzy is an Atlantis-themed slot from BGaming built around a simple but effective idea, I can change the reel size before I play. The game runs on five reels with three possible layouts, 5x3, 5x4 and 5x5, and that also changes the number of paylines, from 5 to 10 to 20. What stands out here is how much that one design choice shapes the whole experience.
The maths sit in the medium-high range, with 96.77% RTP and a top payout of 5,000x the stake. Reviews describe the atmosphere as relaxed rather than dramatic, with a pleasant soundtrack and a polished underwater presentation. I think the theme works well enough, though I am not entirely sold on Atlantis as a fresh hook in 2022 or now.
Symbols and Paytable
Symbols follow a familiar split. I get four low pays from J to A, then five higher-value icons tied to the theme, vases, pendants, helmets, gems and amphoras filled with coins. The reviews point out that exact symbol values shift with the chosen playing field, so the paytable is dynamic rather than fixed across all three setups.
Special symbols do more of the heavy lifting. The Fisherman is the Wild and substitutes for regular pay symbols. Boat symbols act as Scatters for the bonus round. Fish symbols are the unusual part, because they carry random cash values, which gives the base game a different rhythm from standard line-win Atlantis slots.

Bonus Features
3 Boat Scatters trigger Free Spins, with 10 awarded for three, 15 for four and 20 for five. Fish symbols in the base game pay differently, because I need 3 or more on an active payline to collect their random values. That is a neat twist, and compared to the studio's previous work, the focus here is less on visual spectacle and more on layered collection rules.
During Free Spins, Fish symbols become more useful. I do not need them on a payline, I need a Fisherman Wild with them to collect their values. Wilds also fill a meter above the reels, and every fourth one adds 10 extra free spins while unlocking multipliers. The sequence rises from 2x to 3x and then 10x. The bonus can pay well, but the base game can drag a bit before it arrives.
Extra stake options add flexibility. Bonus Buy is available, and it costs 50x the bet to enter the free spins round directly. There is also an x3 Chance option that triples the chance of landing the bonus, but it doubles the stake. That gives the slot a broader market position, because it can suit both patient players and those who want faster access to the main feature.

RTP, Volatility and Layout Choice
96.77% RTP is one of the stronger numbers in this segment, and that helps Big Atlantis Frenzy stand out. Volatility is medium-high, free spins are quoted at roughly 1 in 70 spins, and one review lists hit frequency at 18.05%. Another provider data point shows a hit rate of 4.42, which appears to use a different measure, so I would treat that one with caution rather than read it as a direct conflict.
Layout choice is the slot's clearest selling point. I can play 5x3 with 5 paylines, 5x4 with 10 paylines, or 5x5 with 20 paylines. The design choice to tie reel height to paylines makes the game feel more adjustable than most fixed-grid video slots. It suits players who like to fine-tune pace and screen density without switching games.
