Features 

The features of today’s gambling machines guarantee fun experiences and functionality all to try thanks to the trial demo version. Let’s take a look together at the basic features of these pastimes.

  • Reels: these are the vertical columns placed on the grids of the slots, which move during gameplay. This is where the symbols are represented, which change randomly with each spin. Reels are an essential feature of both traditional gambling machines and online pastimes, as the entire mechanism, is based on their rotation.
  • RTP: This is the rate of Return to the Player (RTP), a percentage of the stake that casino games return in the long run. It is the opposite of the house edge, which is the mathematical advantage of a casino, over a player. Commonly, a high RTP produces better payouts than those with low percentages.
  • Volatility: the frequency with which a software pays out and the average size of payouts, which can be high, medium, or low. Software with high volatility pay huge, very rare payouts, while those with low volatility, can guarantee small, frequent payouts. Finally medium volatility offers average payout sizes, between high and low volatility options.
  • Paylines: that is, a predetermined sequence visible on the game that describes the possible ways a player can make a winning combination. Paylines can be of different shapes and patterns: diagonal, horizontal, vertical, or zig-zag. The winning payline will only award a win if after betting, the symbols on the reels stop in the exact pattern of the payline.
  • Wild: These are icons that replace other symbols and facilitate the creation of winning combinations. These generally do not replace Scatters or Bonus icons, but they pay out when 5, line up on a payline.
  • Scatters: these are icons that offer a Bonus when they stop on the reels, even if they are not on a winning line. Two Scatters often result in a prize, while three or more symbols, commonly unlock the extra feature. 
  • Bonus Round: this feature offers the opportunity to collect significant winnings without spending real money. They can be activated by getting a specific number of Scatter or other unique bonus icons in the base game, such as free spins and extra features. Free spins allow you to turn the reels, without using your personal betting balance. Plus, in Bonus Rounds there are some features that cannot be activated in the base game, such as Multipliers, Wilds, etc.
