Game Overview

Mermaids Treasure Trove is a high volatility slot game played on a 7×7 grid. All symbols pay in blocks of a minimum of 5 symbols connected horizontally or vertically. Only the highest win is paid per winning combination, and all wins are multiplied by the base bet. The game features a tumble mechanic and includes features such as multipliers, free spins, and a maximum win cap.

Symbols and Payouts

Symbols pay according to the number connected in a block (minimum 5). The payout values differ depending on the symbol and the number of symbols in a block. There are also SCATTER symbols and MULTIPLIER WILD symbols.

  • SCATTER Symbol: Triggers the free spins feature and can appear on all reels.
  • MULTIPLIER WILD Symbol: Substitutes for all symbols except SCATTER.

Refer to the in-game paytable for specific payout amounts for each symbol at different block sizes.

Tumble Feature

After every spin, winning symbol combinations are paid, and all winning symbols (except for SCATTER) disappear. Remaining symbols fall to the bottom of the screen and empty positions are replaced with new symbols from above. Tumbling continues until there are no more winning combinations. All wins from tumbles are added to the player’s balance after all tumbles for a base spin have concluded.

Multiplier Wild Feature

  • The MULTIPLIER WILD symbol substitutes for all symbols except for SCATTER.
  • A MULTIPLIER WILD appears after a winning combination that does not already contain one, and appears in a random position within the winning combination area.
  • The WILD starts with a multiplier of x1 and increases by x1 each time it is part of a winning combination and after an explosion of winning symbols.
  • If 2 or more WILDS are in the same combination, their multipliers add together after the combination is paid.
  • WILDS can carry random multipliers: 5x, 6x, 8x, 10x, 12x, 15x, 20x, 25x, 50x, or 100x.
  • If multiple WILDS are part of one combination, priority is given to the combination with the most WILDS or the highest value multiplier.

Free Spins

  • 3, 4, 5, 6, or 7 SCATTER symbols trigger the free spins feature and award 10, 12, 14, 16, or 18 free spins, respectively.
  • During free spins, MULTIPLIER WILD symbols stay on the screen until the end of the round.
  • For each SCATTER symbol that appears during free spins, 1 additional free spin is awarded.
  • Special reels are used during free spins.

Maximum Win

  • The maximum possible win amount is capped at 10,000 times the bet.
  • If a round reaches a total possible win of 10,000x bet, the round ends immediately, awarding the win and forfeiting any remaining features.

Ante Bet

  • Players can increase the bet multiplier to 30x per winning combination.
  • When the ante bet is active, the chance of hitting SCATTER symbols increases.

Volatility and RTP

  • The game is high volatility, meaning it pays out less often on average but has higher chances of larger wins in short periods.
  • The theoretical RTP (Return to Player) can be found in-game, including when the ANTE BET is used.

  • Minimum bet: £0.20
  • Maximum bet: £4
