    RTP and volatility are the 2 most important mathematical characteristics of a slot game. They basically influence how much and how often you win.RTP (return to player, payout ratio or payout percentage) is the long-term statistical rate of total money won divided by total money wagered. This means that if the RTP of a game is 96%, and you start with €1,000,000,000 and then play 1,000,000,000 round ...

    Myth 1
    "Slots have cycles of winning combinations. You can win by observing these cycles and entering during a winning part of the cycle."This is a myth, as slots work on the basis of fair, random numbers. The casino advantage is hidden in the mathematics of the game, and there is absolutely no need to complicate the whole system with any kind of cycle.In fact, it is possible to ob ...
    The simple answer to this question is that slot games are designed in a way that they pay out less than players bet in the long run.Imagine a simple game: you give me €1 and flip a coin. If you get heads, I’ll give you €1.50 back. If you get tails, you lose. It’s quite obvious that the chances are on my side. You can win if you are lucky and play only a few rounds, but I have a clear advantage in ...
    All fair BTC slot machine games have one thing in common: the outcome of each round is based solely on a random number provided by a Random Number Generator (RNG). The random number generated by the RNG "tells" the reels when to stop and therefore decides the game's outcome. This means that the same game with the same random number should always give the same result.The higher the v ...
    Slots are the most popular casino game. The basic rules of this game have not changed since 1899 when Charles Fay set up the first slot machine. A player bets and spins a set of reels with symbols. Each of these spinning reels stops at a random position. The player wins if the reels stop in a way that makes a line with the same symbols. The rarer the winning symbols, the higher the win amount. The ...

    All casino games are configured to give casinos a mathematical advantage, which leads to the casino always being profitable in the long run.
