Online Slot is the biggest online casino category. There’s tons of variety in everything from the number of reels and paylines to the amount and type of features offered. Each of these can influence the way a slot is classified, but the main factor in how well a game is expected to perform is its RTP (Return to Player) value.

This is the overall percentage that a slot is expected to return back to players over a long period of time. This value is calculated using a complicated algorithm that involves running millions of spins and tracking the results.

It’s a hugely popular genre that has become incredibly varied over the years, with games that are themed after TV shows and movies, animals and landscapes, Chinese good luck, Ancient Egypt, sports or even food all getting their own slot versions. But the real magic comes from the fact that slots are really easy to play, with no special skills required and no dress code (PJs work just fine).

Simply place your bets, hit the Spin button and watch as the reels spin around. When a winning combination is landed, your account will be credited with the relevant amount of money. The best way to familiarise yourself with the different mechanics is to check out free play options and demo modes that are often available for each online slot game. Also, be aware of the volatility of each game – high variance slots may offer smaller payouts more frequently, while low-volatility options will provide bigger wins less frequently.
