Rules and Gameplay

Worm King, developed by Cayetano Gaming, transports players to a vibrant, worm-themed universe with a 7×7 grid layout. This slot game breaks away from traditional paylines, employing Cluster Pays mechanics. Winning combinations are formed by connecting five or more symbols either horizontally or vertically. The gameplay is enhanced with Cascading Reels, where winning clusters are removed, allowing new symbols to fall into place. The game’s medium volatility and an RTP of 94.18% cater to a wide range of players, offering a gameplay experience that is as rewarding as it is entertaining.

Bonus Features

Worm King is packed with exciting bonus features that not only add to the excitement but also increase the chances of significant wins:

  • Cascading Reels: Winning symbols are removed, making way for new symbols and potential new wins.
  • Progress Indicator/Feature Inventory: Collect 25, 50, or 75 winning symbols to trigger one of three unique features – Fruit Bomb, Berserker, or Call to Arms. Stash 100 symbols to activate the Worm King feature, each adding dynamic changes to the gameplay.
  • Fruit Bomb: Transforms surrounding symbols into identical ones for bigger wins.
  • Berserker: Clones symbols into 2-7 cells.
  • Call to Arms: Transforms all fruit symbols to the same colour.
  • Worm King Feature: Transforms the king into a 2×2 or 3×3 mega-symbol that moves during cascades, significantly boosting winning potential.


The symbols in Worm King are as colorful and engaging as the game’s theme:

  • Lower-value Symbols: Plums, square watermelons, lemons, and apples, offering up to 4.5x the bet for a cluster of 15.
  • Medium-value Symbols: Pink, green, yellow, and red worms, awarding up to 100x the bet for a cluster of 15.
  • High-value Symbol: The ‘W’ symbol, the most lucrative, providing 250x the bet for connecting 15 in a cluster.


Symbol Cluster of 5 Cluster of 15+
Plums 0.1x 4.5x
Worms (any color) 0.5x Up to 100x
‘W’ Symbol 5x 250x


Instead of traditional paylines, Worm King utilizes a Cluster Pays mechanic where wins are formed by connecting symbols in clusters. This innovative approach allows for more dynamic gameplay and opens up numerous possibilities for winning combinations.
