Free Slots with Wild symbols

Briefly, a Wild is a symbol that replaces any other symbol in the game if it is on a Payline. That is, if in a 5-reel slot you get 4 matching symbols on a Payline, then a Wild symbol can replace the missing 5th symbol on the corresponding reel, thus completing the line.

This concept comes from the joker of tabletop cards, which typically has the function of serving as a substitute for any other card. In English it is also called a Wild Card, and hence the term Wild symbol is born. As already mentioned, the industry is always innovating. Because of this, different types of Wilds have emerged, to refresh the taste of players and evolve more and more the booty of existing games.

Below is a list of the various types of Wild Symbols that exist.

• 

  Colossal Wild

  The Colossal Wild, or Colossal Wild, in New Zealand, is one of the most fun types of Wild to find. These Wilds are, as the name implies, giant, and typically occupy a huge part of the game. They are usually represented by a 3x3 square, in the center of a slot with 5 reels (3x5, therefore). If you combine any symbols that appear on the edges, then the Wild will replace the 3 reels in the middle, thus making it possible to win big prizes.

• 

  Walking Wild

  This cartoon Wild could be translated as "walking Wild". This is because, whenever a symbol of this kind appears on a reel, it will activate a free play, in which you will move (or walk, walking) to one side or the other. Thus, whenever a Wild appears, the player will win a free spin.

• 

  Expanding Wild

  This type of Wild is very recurrent, especially during bonus rounds. Occasionally, the Wild may expand to cover all symbols on the reel it is on, allowing for more wins. Sometimes it can also expand horizontally, occupying other Rolls.

• 

  Sticky Wild

  A Sticky Wild is a Wild symbol that stays in position for more than one spin. It is a fairly common occurrence in the title “Jungle Books", for example. Sometimes several Sticky Wilds can accumulate and eventually, with a lot of luck, you will have the screen full of them.

• 

  Stacked Wild

  Some slots have one or more reels, where the same symbol appears repeated several times in a row. This means that the same can happen with Wilds, being possible to gather a lot on the same reel, within a single play, often without even dealing with the bonus round of the game.

• 

  Random Wild

  Occasionally, a slot can determine a random symbol and turn it into a second Wild, doubling the winning chances that a Wild brings. Other games may already have a second Wild, permanently preset.

• 

  Straight (Diagonal) Wilds

  These symbols feature NetEnt's Fisticuffs slot. The Straight Wild may appear on reel 3, while the Diagonal Wild surprises us on reels 2 and 4. When the 2 Wilds meet on the same play, side by side or diagonally, a third Wild is produced, which will be validated on the next play.

• 

  Wild Duplication

  Games with this feature (such as Wonky Wabbits) can duplicate the Wild by cloning it when it appears and placing it in a random position on the reels. It can also be placed in the position that allows the highest possible prize on that move.

• 

  Spreading Wilds

  Also called “contagious Wilds”, these transform surrounding symbols into Wild symbols, typically using a creative effect.

• 

  Floating Wild

  Floating Wilds will fly over the game as they watch it, waiting for a random spin to land and turn one or more symbols into Wilds.

• 

  Wild Reels

  In certain games, there are Wilds that will take up entire reels. There are also Wilds that are sometimes limited to dice rolls, meaning you cannot win prizes with these symbols alone.

• 

  Wild Generation

  This type of functionality is a bit more complex than the general one. Sometimes, when you hit a combination without the participation of a Wild, the symbols that gave you the prize can turn into a Wild on the next spin. Thus, if this new Wild generates a prize, it will remain in the same place until the next round.

As you have already seen, Wild symbols can be very beneficial. Thus, try to play slots with the most generous application of Wilds possible, as well as with the maximum number of extra features, which allow you to accumulate prizes.
