Most modern slots feature wild symbols. Players at gambling sites like Casino Online Pistolo Casino look forward to these symbols appearing on the screen, as they award additional wins and are accompanied by interesting visual effects. Users should be aware of this game element. Below, we'll discuss how wild symbols work.

A Brief Description of the Wild Symbol

In video slots, the wild symbol originally replaced other symbols, similar to how jokers work in card games. If four identical symbols appear on an active payline along with the wild symbol, the combination will award a win as if five identical symbols appeared on the screen. Players should remember that the wild symbol can only substitute for standard symbols. It cannot be used as a Scatter or bonus symbol.

Let's look at some features of wild symbols.

  • Reel specificity. In many games, wild symbols are programmed to appear only on certain reels, e.g., the three middle ones. It prevents payouts from spreading too frequently across the entire grid.
  • Symbol weighting. Wilds are usually mapped to fewer virtual stops on the Random number generator than low-value symbols. It preserves their status as a premium feature.
  • Interaction with clusters. In slots with cluster payouts, the wild symbol doesn't simply fill a line. It connects adjacent symbol edges and acts as a bridge between separate groups of similar icons.

If users want to know how the wild symbol works in a particular game, they should consult the paytable.

Basic Types of Wild Symbols

The ability to substitute for other icons is a key aspect of the wild symbol in Casino Online slots. Still, some developers add additional features that make this symbol even more useful. Below, we'll analyze the basic types of wild symbols.

  • Classic wild symbols. They appear in the main game and bonus rounds and have no additional functionality.
  • Sticky wild symbols. These remain in place for a certain number of spins, e.g., during the free spins round, while other symbols on the reels rotate. It increases the chances of winning while the wild symbol remains on the screen.
  • Stacked wild symbols. These appear on top of each other to increase the chances of landing a winning combination or can expand vertically. If these symbols fill an entire reel, they may merge into a single mega symbol.
  • Expanding wilds. This version expands vertically and horizontally, filling more reel positions. This feature increases the chances of winning, as fewer symbols are needed to trigger a payout.
  • Walking wilds. These symbols move during the game. For example, with each move, they can shift one reel to the right until it disappears from the screen.
