Big Atlantis Frenzy Demo & Review

Big Atlantis Frenzy review

Big Atlantis Frenzy is an underwater fishing slot with a customisable grid. A Reel Size Change feature lets you choose the reel size and the corresponding number of paylines before you spin.

Fish symbols carry random cash amounts, and the usual bonus symbols, wilds and free spins are present. You can buy free spins with a chosen number of lines, or buy Chance x3 to triple your odds of reaching the bonus naturally, but not both at once. BGaming rates the game medium-high volatility with a 5,000x maximum, and the 96.77% RTP is good. Free spins land frequently, about once every 70 spins on average.
