Mermaids Slot Overview
Mermaids from NetEnt is a 5x3 video slot built around coloured Progress Wilds and three linked bonus rounds. What stands out here is the design choice to tie nearly all of the action to collection meters above the reels, rather than to a traditional scatter system. I find the underwater setting polished and easy on the eye, though the game feels lighter than its high-volatility label suggests.
Facts are a little messy across review sources, but the clearest picture is a slot with 20 fixed paylines, high volatility, a default RTP around 96.09%, and a top win just under 2000x. Compared to the studio's previous work, the setup is fairly straightforward. The hook is not complexity, it is patience, because the strongest bonus takes the longest to reach.
Game Symbols
Eight regular pay symbols sit on the reels, split between royals from 10 to A and four mermaid characters. Five matching royals pay from 3x to 20x the bet, while five mermaids pay from 30x to 100x. Two of the premium mermaids also pay from two of a kind, which is a useful touch in a game that can otherwise feel sparse between features.
Four wild symbols are in play. Three are coloured Progress Wilds, purple, green, and white, and each one fills its matching Progress Globe when it lands. The fourth is a regular wild that appears through Random Wilds. All wilds substitute for regular symbols, and five wilds pay 100x the bet. The absence of a traditional scatter is a notable design choice.

Mermaids Bonuses And Special Features
Three Progress Globes drive the entire feature set. Each starts with 10 collected points, then fills as matching Progress Wilds land. Purple reaches the Picker Bonus at 15, green reaches Wild Spins at 30, and white reaches Mermaid Spins at 60. I like the clarity of this structure, but the base game can drag a bit while you wait for the white globe to build.
15 shells appear in the Picker Bonus, and I get 3 picks. Rewards include cash prizes from 2x to 50x the bet, plus direct entry into Wild Spins or Mermaid Spins. If a free-spin feature lands here, it triggers without resetting its own globe. That rule matters, because it keeps long-term progress intact.
10 free spins are awarded in both free-spin modes. Wild Spins uses Random Wilds to place 2 to 6 regular wilds on every spin. Mermaid Spins does the same, but removes all royal symbols from the reels for the duration. That is the best-paying state in the game, and the one most players will want, though it can take time to arrive naturally.

Mermaids RTP, Volatility, And Max Win
96.09% is the main RTP figure attached to Mermaids, with some reviews also mentioning lower operator settings around 94.15% or 94.10%. Volatility is high, and the hit frequency has been listed at 25%. Betting usually runs from 0.20 to 40, which keeps the game accessible, but not everyone will enjoy a high-volatility slot with such a restrained ceiling.
1974.3x the bet is the widely cited maximum win, while one official listing puts the cap at 2007xBet. Either way, the gap is small and the broader point remains the same. For a high-volatility release with two free-spin modes, the maximum payout is modest. That limits its appeal if I am specifically chasing big-end potential.
