What To Know Before Playing Online Slots

Options are infinite for online slots games; however, avid gamblers suggest playing slots with exciting and rewarding features, but features do not guarantee more payout. Pre-prepared is better than being ignorant, and even slots are luck-based, but knowing the features may help you select the best from the rest.

  • Reels: The basic feature of any slot game is their reel that spins to form the winning combos. Modern slots come with a variety of reels format starting from 3 to 15; with every increasing reel, the slot's complexity level also increases.
  • Paylines: Almost all slot games have paylines on which the winning combos form that reward payout. You'll find slots with classic 1 to 3 paylines to modern video slots that boast 15 to 30 paylines up to 117649. Standard slots pay players from left to right on the payline with two or more matching symbols in a row.
  • Wilds: Thousands of online slots, classic or modern, have Wild symbols on their reels; these symbols substitute all the symbols except scatter on the grid to increase players' winning chances. The Wild symbols also increase players' payout when appearing during the bonus round. Wilds come in many shapes on online slot games, such as expanding wilds, stacked wilds, sticky wilds, shifting wilds and transferring wilds.
  • Free Spins: The most anticipated bonus round of any slot game is usually triggered by aligning Scatter symbols on the active payline in two, three or more numbers. The amount of free spins varies from one developer to another, along with the boys' round style.
  • Volatility: It's the frequency with which a slot game payout. You can play slots with low, medium and high volatility. The lower the volatility, the more frequent will be a win, but at a lower value. However, with high volatility slots, wins are not regular, but the winning value is higher. It depends on players which volatility suits their gaming style.
  • RTP: The RTP of the slots is the payout percentage players get over a period. You can find the theoretical RTP of any slot game on its paytable or slot review sites. The higher the RTP, the higher your payout percentage. If you plate a 97% RTP slot with £100, you'll get £97 in return, and the rest 3% add to the casino house edge.
  • Re Trigger Free Spins: Some online slot games offer players a chance to re-trigger the free spin round by landing special symbols. You may re-trigger to a certain number or for unlimited times.
  • Multipliers: Many online slots include an amazing feature to increase players’ winning chances by attaching multipliers with the win up to 100x or more.

Besides these basic features, you may also find gamble, scatter pays, increased winning ways, cascading reels, cluster winning combos, and many more. Online developers are amazingly creative with slots gameplay, and they are constantly introducing innovative features boosting gameplay excitement and player's payout simultaneously.
