    How to Play Slot Games

    Most people consider casino slot games and video slots easy to play and tend to disregard their status as actual games. This might hold true for the classic fruit machine games that displayed 3 reels and only including 12 symbols in total.

    However, in 2021, slots games have reached a new level with bonus rounds, extra features, free spins, mini games, jackpots, different sets of reels and many more features that make each title differ and stand out from the rest.

    This is particularly good news for free slot games fans, as it means that their favourite game is constantly getting better. However, it also presents a challenge for them - keeping up to date with the new additions and being aware of how these might influence their winning potential.

    Read below some of the basics involved in slots gaming and how they can determine whether you will win or lose.

    Slots Terminology to Play in 2021

    • Return to Player – the RTP determines the edge of the casino over the players. To get the true RTP value of a slot game, one must bet over 1,000,000 spins.
    • Volatility/Variance - this is a rating that all online slots carry, and it highlights how often a slot pays out and the size of the wins. The lowest the volatility levels the more frequent the wins but lower the prizes; and vice versa.
    • Paylines - most up to date slot games have 25 paylines, which can all yield different winning combinations.
    • Megaways - these are the exception to the above rule, as these new online slots type has 0 paylines. Instead, players win as they land similar symbols from the left to the right in adjacent reels. Same mechanic is at play in 243 ways and 1024 ways to win slot machines.
    • Reels - each slot is different but aim to play on slot games that have at least 5 reels and therefore potential for more winning combinations.
    • Wilds - the wilds can land on any reel and they substitute all other symbols. When one lands on the reels, it can help players form winning ways on video slots.
    • Scatters - the scatter is the most special symbol, one that pays wherever it lands on the reels. Further, scatter symbols often unlock the bonus features, where players can land bigger wins.
    • Free Spins - slot games with free spins are the most loved today, as these tend to offer higher rewards than the base game and also allow the player to sit back and look at their bankroll skyrocketing. 
    • Sticky Wilds - wild symbols are apparent in most free slot games, but sticky wilds are special as they do not reward the player and then vanish.
    • Multipliers - multipliers are very often combined with the free spins rounds and are one of the players’ favourite type of bonus.
    • Jackpots - Daily, Progressive jackpot, Local, and instant jackpots do not only offer different amounts of rewards, but also affect the volatility of the slot games that feature them.

    The above are just some of the factors that play into slots gaming. When spinning slot games, the goal is to match 3 or more identical symbols on the reels - and all the above determine the pay out; increase the bets or enter the bonus features to allow for easier and higher wins.

    How Can I Win at Slots Games?

    There are different ways that can lead someone to a win at slots. When referring to winning a single round in a particular casino slot game, then one of the following needs to happen:

    • After you have spun the reels of the game, then the animation will end, and the symbols will fix on the slots.
    • Wins usually occur from the left to the right, if 3x identical symbols land on the active paylines. Some high paying symbols pay even if just 2 identical symbols match.
    • Exception to the above rule pose the slot games that have no paylines (Megaways, 248 ways to win, 1024 ways to win). In these, a player must at least land one identical symbol on 3 adjacent reels. Some slot machine games also pay both ways (right to left and left to right), with the most popular today being Starburst.
    • Wild symbols and scatter symbols break the above rules and help players form bonus wins and unlock extra rounds.

    The general idea of winning at slots online is the one we described above, but each game has its own intricacies, so always have a look at the paytable for more catered details.
