Inside the game

How Mermaid’s Treasure Trove works

Tumbles create opportunities, winning clusters can leave local multiplier Wilds, and the bonus makes those local values persistent without guaranteeing they will connect again.

Seven-by-seven cluster payments

Groups of matching symbols pay wherever they touch on the large grid, disappear and allow new icons to tumble into the empty positions.

Winning groups can create Wilds

A successful cluster may leave a multiplier Wild behind, giving the next tumble a fixed substitution point with an attached value.

Useful Wilds grow one step

Whenever an existing multiplier Wild belongs to another paying cluster, its value rises by one before the next replacement symbols arrive.

Free Spins preserve Wild positions

Ten to eighteen awarded spins keep multiplier Wilds on the board between turns, while normal tumbles and attached symbol boosts continue.

Whether an existing Wild reconnects before replacement symbols move away

What to look for in the demo
  1. Require the Wild to join the next win

    A multiplier increases only when its Wild participates in another paying tumble. A high value sitting beside unrelated symbols contributes nothing to that cascade.

  2. Read attached symbol boosts separately

    Paying icons may carry random 2x–100x multipliers of their own. Distinguish that one-off value from the board position occupied by a growing Wild.

  3. Map sticky positions during Free Spins

    Feature Wild multipliers remain between turns. Note whether new symbol drops continue connecting to those fixed locations rather than watching the total meter alone.

04 / The SlotsCollector take

A spacious cluster slot where the most valuable object may be a Wild with somewhere useful to connect

Mermaid’s Treasure Trove pays clusters on a 7×7 tumble board. A Wild created by a win grows by +1x whenever it helps another cascade, and Free Spins make those Wild values sticky for the entire round.

Mermaid's Treasure Trove fills a 7×7 board and pays groups of matching symbols, then removes successful icons for another tumble. A winning combination can produce a multiplier Wild. If that Wild participates in a later paying cluster, its value increases by +1x and can continue growing through the same sequence. Paying symbols may also arrive with attached multipliers between 2x and 100x, creating sharp one-spin boosts alongside the position-based Wild development. Three to seven scatters award ten to eighteen Free Spins. The important upgrade is persistence: Wild multipliers remain in their positions throughout the feature, allowing future spins to reconnect with values built earlier. The potential is attractive, but a fixed Wild is only as useful as the symbols landing around it. A large multiplier stranded at the edge may contribute less than a smaller central Wild that repeatedly joins clusters. Medium volatility and a 10,000x maximum are the official settings; the outcome still depends on both value and location. Use the demo to trace one Wild from creation through each successful connection. Keep attached symbol multipliers separate, because they do not represent the same persistent resource. During Free Spins, mark the board positions that have become anchors and judge how often replacement symbols reach them. This produces a much more honest read than celebrating the largest number visible. The game fits players who enjoy board state carrying across cascades and who are comfortable interpreting cluster geometry. Those who prefer a single global multiplier may find several local values difficult to follow, especially on forty-nine positions. Its strongest quality is that progress stays visible; its main risk is assuming visible progress will necessarily find another win.
