Wild symbols are one of the most important elements of slot machines. Players often refer to them as a kind of joker, because they can substitute for any of the regular symbols on the reels. In practice, this means that the wild symbol significantly increases the chance of forming a winning line and in many games it also acts as a win multiplier.
Each slot machine has its own wild symbol design – some are simple, others are elaborate or even animated. Some players even purposely seek out slots where the wild symbol appears frequently, and avoid those where it is completely absent.

What is the meaning of the wild symbol for the game?

The wild symbol tends to be a key element of strategy for many players.
While it may at first glance seem like a feature that increases the payout percentage, the reality is different. While the wild symbol can increase the chance of a winning combination, the long-term return to play (RTP) remains the same.
The advantage of the wild symbol therefore lies more in the short-term win situations it can create or multiply – rather than in actually increasing the overall slot payout.

Types of wild symbols

Online slots today offer several different types of wild symbols. Each one works a little differently and can have a different effect on the outcome of the game.

1. Expanding Wilds

This type of wild will expand to the entire field or even the entire reel when it hits the reel.
On subsequent spins, it can grow, expanding to cover more and more of the playing field.

2. Walking Wilds

These symbols move on the reels in every other spin.
They substitute for other symbols and complete the paylines, but only appear for a limited number of rounds.

3. Sticky wild symbols

These wilds do not move after landing and do not immediately disappear on the next round.
They remain “stuck” in place for several spins and may yield more wins during those spins.

Examples of wild symbols from popular games

Multiplay 81 – a wandering wild with high power

The wild symbol in Multiplay 81 bears the same name as the slot machine itself.
It is a simple icon with the number 81 and substitutes for any symbol in a winning combination.
It functions as a wandering wild and applies on all 27 or 81 paylines.

Hunter’s Dream 2 – The Wilds That Also Multiply Winning

The game features two wild symbols – fire and hunter’s hut.
Both substitute for missing symbols in a winning combination and also multiply the win by 2× for each wild.
Thus, if two wild symbols appear in a payline, the win is multiplied by 4×.

Multi 5 – wild that completes lines and multiplies wins

The wild symbol is again named after the game – Multi 5.
It replaces any symbol except the special bonus icons “THREE”, “REEL” and “BONUS”.
Each active wild symbol also doubles the win and the multipliers stack with each other.
