Online slot machines at casinos

People have loved playing slot machines since the beginning of the 20th century. The first slot machine was invented in San Francisco, USA. Several years later, slot machines were all over the United States. It was only in 1931 when the first money payouts were made. Until then, players only received material prizes.

Today, slot machines are much more sophisticated and interesting than back when they just started. Players can enjoy video games, video slots, not only at classic casinos but also at online casinos. Playing the slots today brings with it a lot more entertainment. They offer many more features and opportunities to win.

Basic rules for online slot machines

You cannot influence the result of slot machines with any form of strategy. The reels spin with the push of a button, tap of the display, or pull of the lever. The machines usually stop the spinning process. Winnings depend on the number of the same symbols or a combination of symbols on a winning line. Each symbol has a different value. Today's slot machines come in many forms. Some have multiple levels.

The configured payout ratio has an impact on the amount that can be won. Simply put, the slot machine gives out money to someone from time to time. When this occurs, however, cannot be influenced, nor can the sum of money won.

Each slot machine offers some kind of bonus. You can win extra coins thanks to bonus games, usually themed games beyond the reels. Almost all slots offer Free Spins, which can multiply your winnings. Another common bonus is the Wild symbol, which substitutes all symbols and can support the player towards winning.

All information about winning combinations and winning payouts can be found upon clicking on Paytable.

Jackpot 6000

For many years now, Jackpot 6000 has been a popular 3-reel slot machine with 5 rows with jokers. You can multiply your winnings in "Heads or Tails" mode and the Supermeter mode. You can win up to 6,000 coins in a single game round.

You can bet on up to five winning lines in each round (spin). The minimum bet is one coin per betting line and the maximum bet is two coins per line - thus the maximum amount of coins covering all five winning lines is ten.

Winning symbol combinations are shown in the winning table in the top left corner of the machine. The joker winning table shows winnings for three jokers in a winning line for various betting levels. If you bet just one coin, winnings in the winning table will be reduced by one half.

If you win after betting the maximum bet, you can transfer to the Supermeter mode. The bets in Supermeter mode are higher: the betting level is automatically 20 coins with all 5 active lines. Besides winning money based on the winning table, the benefit of the Supermeter mode is the chance to win two visible jokers wherever on the reels. Each combination of two jokers pays a mystical prize of 10 to 6,000 coins.

Twin Spin, fruit slots

Twin Spin, fruit slots

The Twin Spin online slot machine is a new product from Net Entertainment, released in 2014. It filled the gap between machines from this leading game supplier and immediately became one of the most popular slots. A 5-reel, standard Las Vegas style "fruit" slot machine able to compete with the very popular Sizzling Hot machine had been missing for a long time.

Twin Spin is a 5-reel video machine, with the symbols 10, J, Q, K, A, cherry, bell, BAR, 7, diamond and Wild symbol - joker. The wild symbol replaces any other symbol in the winning line. With an unprecedented 243 winning lines, it offers a maximum total of winnings of €135 000 by betting the maximum bet of €125. The game lacks a jackpot which is substituted by bonus games during which multiple reels spin at the same time - with the same symbols. This way a simple win can turn into a MEGA win.
