Rules and Gameplay

The Coba slot machine offers a unique and immersive gameplay experience set against the backdrop of an ancient Mayan city. Players win by forming clusters of 5 to 15+ matching symbols anywhere on a 7×7 grid, as long as the symbols touch. The game introduces an innovative avalanche/gravity mechanic where winning symbols are removed, allowing new or existing symbols to tumble down, potentially creating new winning combinations in a cascading fashion. The presence of a Snake Meter on the side adds a strategic layer to the game, as filling it unleashes snakes that move around the grid to create wins and potentially generate massive multipliers.

Bonus Features

Coba is rich in bonus features that enhance the gaming experience and offer lucrative opportunities:

  • Snake Feature: Triggered by filling the Snake Meter, releasing up to 6 snakes that can grow by eating matching symbols and generate double wild multipliers.
  • X-iter Feature: Offers 5 different gameplay options, allowing players to directly influence the level of action on the reels with varying stakes.
  • Gravity Mechanic: Winning symbols are removed, and new symbols fall into place, creating opportunities for consecutive wins.
  • Multiplier Wilds: Created when snakes cross paths, multiplying the value of wins they contribute to.


The symbols in Coba slot are meticulously designed to fit the ancient Mayan theme, with a mix of low and high-value symbols:

  • Low-value Symbols: Represented by ornamental Mayan carvings.
  • High-value Symbols: Include premium gems and gold masks, offering higher payouts for larger clusters.
  • Wild Symbols: Substitute for any regular paying symbol to form or enhance winning clusters.


Coba offers the potential for substantial payouts, with a focus on cluster wins and multiplier effects. Here’s an overview of the payouts:

Symbol 5 Symbols 15+ Symbols
Low-value Symbols 0.1x to 1x the bet Up to 50x the bet
High-value Symbols 1.5x to 15x the bet Up to 500x the bet

The game boasts a maximum win potential of up to 25,000x the player’s stake, achievable through the combination of multiplier wilds and the strategic unleashing of snakes across the grid.


Instead of traditional paylines, Coba utilizes a cluster pays system where wins are awarded for clusters of 5 or more matching symbols touching horizontally or vertically. This innovative approach to forming wins offers a dynamic and engaging gaming experience, distinct from the classic line-based slot games.
