All there is to know about 20 line slots

When you stumble upon 3 reel 20 line slots for the first time, you might not realize the difference between them and games with fewer ways to win. The difference consists in the fact that just as the name suggests, you have 20 different winning combinations each time the spins are set in motion.

🎰 What are paylines?

To better understand 20 lines slots, you need to begin by learning what pay lines stand for and how they influence the gameplay. Essentially, these are a mix of slot machine symbols that create a winning combination and the higher the number, the more frequent the winnings.

As mentioned above, 20 line slots are the pinnacle of evolution, but the early slots were far less complex. The first game for example, was produced at the end of the 19th century by Charles Fey and it went by the name of Liberty Bell. It had a single pay line and players would win the biggest amount by lining up three bells in a sequence.

Much has changed over the years and 20 payline slot machines provide many more ways to win wrapped up in the exciting gameplay. They’re even the games with the highest number of winning combinations, as the best online casinos in the world offer slots with more than 100 pay lines.
