Why Do Some Slots Become So Popular?

Slots players have many different reasons for gravitating towards certain online slots, but most of the best online slots have one or more of the following qualities:

Progressive jackpots - even if you play slots for fun you still dream of winning a massive multi-million dollar jackpot, don’t you? The most popular online slots tend to be progressive jackpot games that offer the chance of life-changing money.

Modern graphics - slots are no longer clunky old machines of bars, bells, and cherries, but ultra-modern experiences that can look more like a blockbuster video game than a one-armed bandit. The best slots have the best graphics and gameplay.

Reliable payout structure - most online slots have similar RTP (Return to Player) percentages, but some are high volatility (infrequent but high payouts) and others are low volatility (frequent, smaller prizes). Many players prefer one or the other or land in the middle, but consistency is key.

Some of the most popular online slots themes include:

• Irish - the luck of the Irish is famous, and these games give you a chance to find a pot of gold at the end of a rainbow!
• Ancient Egypt - the riches and wealth of this mighty empire are legendary, and you can unearth a Pharaoh’s share of online slots prizes!
• Films, comics, and TV - people love slots themed around their favorite television shows, movies, and fictional characters.
