Key Slot Terms
Since slots are the most popular types of entertainment, it will be right and logical to start with them. Before you launch your first slot on RocketPlay, you should learn the basic concepts.
- Spin. This is one rotation of the reel in the game. Each spin is an opportunity to collect a winning combination of symbols on the screen;
- Paylines. These are combinations of symbols that determine your winnings. Classic slots have only 1 payline. And in modern video slots, there are hundreds of them;
- Wild. A special joker symbol that replaces other symbols and helps form a winning combination;
- Scatter. Another special symbol that usually activates a bonus round or gives free spins;
- Free spins. These are free attempts to spin the slot. They can be obtained for the appearance of certain symbols, or for participating in promotions and bonuses;
- Jackpot. This is the maximum winning amount on slots. Jackpots can be fixed and progressive, where the amount will grow due to players’ bets.
Knowing these terms, you can easily understand how to start playing.
Basic Terms in Card and Table Games
Card and table games are no less popular. Like slots, they work on the basis of a random number generator. But here other rules, game mechanics and terminology are used.
For example, blackjack is a popular card game. Here, your goal is to collect 21 points or the closest possible value. In this game, Bust is possible. This means that you have collected more than 21 points, which automatically means a loss.
Roulette is a game where you need to bet on a number, color, or a group of numbers. The winnings directly depend on the sector where the ball stops.
Pay attention to the concept of House Edge. It means the mathematical advantage of the casino over the players. For example, in the European version of roulette, this advantage is about 2.7%.
Bankroll is the money that the player allocates for games. The amount is displayed in your personal account after making a deposit. The most important element of responsible gaming is proper bankroll management.
Terms in Promotions and Bonuses
Some players do not activate bonuses and do not take part in promotions because they do not know what they mean.
- Welcome bonus. This is an offer from the casino for new players. Most often, it is 100% of the first deposit amount, or a free spins package. It can be activated only once;
- Wager. When activating bonuses, it is important to consider the wager size. It indicates the number of times you need to bet to withdraw your winnings. For example, if the wager is x30, then the bonus must be wagered 30 times;
- Cashback. Players can receive part of the amount that the casino won from them. Most often, cashback is credited once a week;
- No deposit bonus. This is a special gift that the player receives without having to top up the balance. Usually, they give free spins and bonus money;
- Reload bonus. A special reward for regular customers. When making deposits, they receive a certain percentage of this amount as a bonus.
Having understood the basic concepts, it will be easier for you to understand the essence of the promotion and decide which bonuses to participate in.
General Expressions and Concepts
You will also find that it is beneficial that you learn a few more concepts that are actively employed in the sphere of gambling.
As an instance, a high roller is a gamer who likes to bet big. And Tilt is the psychological condition of a player who loses, when he ceases to act according to the plan and plays impolitely.
RTP – return to players should also be known. The indicator is expressed as a percentage, and it reflects the average returns to the players that the slot machine makes. As an illustration, when the RTP is 96, then in 100 units of bets, the player will get 96 in the long run.
Volatility is an indicator of risk. If volatility is low, then winnings will be frequent, but small. If volatility is high, winning combinations will fall out rarely, but there will be an opportunity to take a large amount.
