Texas hold ’em (also known as Texas holdem, hold ’em, and holdem) is one of the most popular variants of the card game of poker. Two cards, known as hole cards, are dealt face down to each player, and then five community cards are dealt face up in three stages. The stages consist of a series of three cards (“the flop”), later an additional single card (“the turn” or “fourth street”), and a final card (“the river” or “fifth street”). Each player seeks the best five-card poker hand from any combination of the seven cards: the five community cards and their two hole cards.( 資料來源 )
In Texas hold ’em, as in all variants of poker, individuals compete for an amount of money or chips contributed by the players themselves (called the pot). Because the cards are dealt randomly and outside the control of the players, each player attempts to control the amount of money in the pot based on the hand they are holding,[1] and on their prediction as to what their opponents may be holding and how they might behave.( 資料來源 )
Casino operators rely on tiny microchips known as number generators (RNGs) to ensure the unintended effect of spins on online slots. What is RNG technology? Simply put, RNG is a microchip designed to continue to generate numerical sequences, even if the slot game does not play. This set of numbers is fast-paced – and soon means faster than man, billions of times a second!
Random is the key to all kinds of casino games. That is why they are considered opportunity games. It is up to you to win or lose the spin of the reels. Of course, there are casino games where players can influence the outcome. Take blackjack as an example, with several strategies players can use to increase RTP percentages over time. The fact is that while blackjack players can make wise decisions using strategy, you cannot guarantee a winning hand. The shuffling and operation of the cards are unpredictable, as is the spinning of the reels inside the slot game.（原文出處：https://gamerules.com/rng-mechanisms-in-slot-machines-explained/ ）
