How To Play Online Slots

Special Symbols And Combinations

Slot machine players need to understand its features first. Possessing that understanding enables people to know what they are enjoying and what they can expect. Many games feature traditional icons like bats, 7s, cherries, etc. However, gamblers like animated icons that feature top designs and sounds. Below are the various signs gamblers encounter when playing slots.



The icon is a reward function that is preferable to many gamblers. Many five-reel games these days have the symbol, and you can find it on the paytable. The icon can substitute all other game symbols to create a winning combination.

Often, the wild does not replace unique slot icons that initiate a jackpot or bonus session. The symbol improves the winning probability, but customers need to check whether it emerges on all reels only a few. Slot machines keep evolving, and these days, gamblers get different wild symbols.

Examples include:

  • Expanding wilds: The icons alter their size when players find them. They substitute the symbols they cover and possess higher chances of being part of the pay line.
  • Walking wilds: The symbols remain on the reels for several rounds after players find them. They often move from one reel to the other until they leave the game screen.
  • Sticky wilds: Once players find these icons, they stay in their place for several rounds. They improve the probability of winning.
  • Multiplier wilds: The symbols possess an extra reward effect. They can affect the amount customers win. Unfortunately, they are rare. You can only find them in a few slot machines, and it is not easy to hit them.


The bonus feature is in many video slots. The symbol is rare and difficult to find. The best thing about it is that it does not need to be part of a pay line to initiate an action, and its impact varies per game. Often, gamblers need to have several scatters on any place on the reels. You may need three icons to initiate the bonus.

Some of the rewards gotten from scatters include free spins. You get a chance to play more rounds and win more. For instance, you can receive five to fifteen spins where the win depends on your last wager that initiated the bonus.

The free spins can also come with additional offers like multipliers that boost earnings more. The scatters may even reward customers without other symbols. Players need to check the paytable to know what rewards to expect.

Payouts from scatters are often lower than those of a complete pay line with high-paying icons. The only good thing is that they do not need to emerge on a pay line to reward customers. As long as they appear anywhere on the reels, you will gain something.



The sign multiplies earnings. The icons emerge on the reels like other signs, but they increase the payout by 2x, 5x, 7x, etc.

A multiplier can be a regular sign that features a different thing to show that it multiplies earnings. The highest rewarding multipliers also function as wilds. So, they can improve the profits on any combination.

Many slot titles do not have multipliers. Those that emerge on the reels are also free to make up for the high money returns.
