Slot Machines / Slotmachine

Slot machines get their name from the coin slot - the slot - in which the coins were inserted in classic slot machines. Also the symbolism of the fruit machines of that time is often used in modern video slots such as Fruit Super Nova, Hot to Burn or Epic Joker. The fruit symbols date back to the time when gambling machines were banned. Fruit machines were slot machines disguised as gumball machines. The prize was chewing gum with the corresponding fruit flavor. In classic machines today you can still find fruit symbols such as lemons, cherries, apple and melons, complemented by grapes, bananas or strawberries. Also coins are still used as symbols for your cash bet.

The first electromechanical slot machine with 3 reels was Money Honey and was developed by Bally in 1963. This machine could make automatic payouts up to 500 coins.

Most modern online casino slots have 3 to 5 reels and 3 to 4 rows. Depending on how the winning symbols appear on the reels, you may or may not get a win. This is decided by chance. There are different paylines that determine which arrangement of symbols leads to a win. This ranges from one payline to 117,649 paylines in a Megaways slot. Most modern slot games additionally have Wilds symbols, which can substitute for other symbols like a Joker in a card game. To make the games more varied, many game manufacturers build bonus features such as free spins rounds into the gameplay.

When playing in the online casino, you have to observe various rules. For example, there is a maximum bet of 5 euros per spin. This means that you can bet a maximum of 5 euros per game round on a slot. There must also be a pause of 5 seconds between two game rounds. Many gambling houses also no longer offer an autospin function, as this has been banned in Germany. Reputable online casinos make sure to follow all these rules.

Video Slot

The first video slot was the slot game "Fortune Coin", which was developed by Walt Fraley in 1975. It was the first game that could be played on a screen. Unfortunately, at that time the graphics were not good enough to show authentic spinning reels. The sector experienced a big boom in 1994 when Bally introduced the Game Maker. On this machine it was possible to play several games on one screen.

Nowadays, video slots are equipped with all sorts of bells and whistles and work just as well on a smartphone as they do on a PC or laptop. The graphics are spectacular and in-house sound designers provide perfect sounds to give you as a player enough variety, fun and action.

Each video slot uses a random number generator (RNR). This ensures that the game is fair and chance decides who wins or loses. An important indicator in this area is the RTP of a game - the"Return to Player". This indicates what percentage of the deposits is paid out again as profit to the players. So the higher the value, the better for you. So if a game has an RTP of 96%, it means that 96 of the deposits are paid out to the players as winnings and the casino gets the remaining 4. In this case, the casino has a house edge of 4%.

Another special form of online slots are the Megaways games with their 117,649 paylines. In these slots, the number of paylines and symbols per reel is not known at the start of the game. Two to seven symbols then appear on each of the 6 reels. Depending on the number of symbols on the reels, the number of paylines also changes. The bet is made here per spin and not by the number of paylines. Megaways slots tend to have a high variance. This means that they pay out high profits, but less frequently.

The most popular Megaways games are

  • Gonzo's Quest Megaways
  • Big Bass Bonanza Megaways
  • Aztec Gold Megaways
  • Wolf Power Megaways
  • Triple Fruit Deluxe Megaways

When you play slots with high volatility, the risk of losing is higher, but the winnings are also significantly higher. In low vol atility slots, the winnings are lower, but the probability of winning is higher, because the winnings are paid out more often.
