Online slots make up over 70% of all casino games and offer players a variety of themes, volatility levels and game types. Whether you prefer a classic fruit machine or the latest 3D slot, the best online slot sites will feature an expansive collection of titles from leading software studios. You can expect to find all sorts of Megaways, instant wins and Megaclusters slots, along with high-volatile and low-volatile games and a range of betting limits to suit all budgets.

You can play online slot games from your desktop, mobile phone or tablet. Depending on the game, you can also take part in tournaments and win real cash or prizes such as holidays and gadgets. Most real money slot games have free play options so you can practice before risking your own cash.

Unlike traditional slot machines, which only have three reels and a handful of symbols that line up in specific combinations to trigger payouts, online slots have many more features that make gameplay more interesting. These features include wilds, scatters and other special symbols that can substitute for any other symbol on the reels and turn losing symbol combinations into winning ones.

In addition to these features, some online slot games have progressive jackpots that keep growing until someone hits them. These jackpots can be won through a combination of symbols, a bonus round or a random event. Some of the biggest jackpots are on offer at Bovada – a fully licensed and regulated site that has been around since 2011. You can deposit and withdraw using Visa, MasterCard, Discover, DraftKings gift cards or Play+ cards, a wire transfer from MVB Bank, an online banking account with a casino or a barcode at participating venues.
