There are now more than 2,200 slot machines available online today and the vast majority of these games can be accessed by UK players at several top UK online casinos. Most online slot machines today either have 3 reels or 5 reels and they can have anywhere from just 1 winning payline up to having as many as 100 paylines.
The slightly newer online slots from various software providers have a ‘Win Ways’ format rather than a standard payline format and these games can have 243 ways to win per spin or 720 ways to win per spin, up to as many as 1,024 ways to win per spin. You will find that the betting structure though is fairly identical. For example the cost-per-spin on many of today’s 243 ‘win ways’ slot machines is identical to a 30 paylined slot machine.
Today’s online slot machines have Wild Symbols which can substitute most of the other symbols on the reels to help generate new line wins that otherwise weren’t there. These Wild Symbols also come in many different shapes and sizes, but the standard Wild Symbols will only ever cover just one symbol position on the reels and they can land on any of the reels. You can also now find Expanding Wilds, Sticky Wilds, Grouped/Stacked Wilds and Trailing Wilds, plus numerous other variations.
A line win will usually occur on most online slot machines when three or more matching symbols land in consecutive order across any of the paylines/win ways. You can also find Scatter Symbols which generally trigger a Free Spins Bonus Round when three or more show up anywhere on the reels, in no particular order, or they can trigger some kind of on-reels click me bonus where you get to click on one of the Scatter Symbols to reveal some kind of coin prize or a stake multiplier.
The other special symbols to keep an eye out are the Bonus Symbols and these generally have to land in a certain position across the reels for a bonus round to trigger. This fun side game may take place on the reels, but it usually takes place on a second screen away from the reels. Most bonus rounds are fairly simple and generally require you to pick objects by clicking on them to reveal hidden prizes. Some bonus rounds require an element of skill and you are generally guaranteed some kind of bonus prize each time a bonus round triggers.
