Online slots casinos are plentiful and varied. There are literally hundreds if not a few thousand online casinos that offer slots games in one form or another. Some offer a standard mix of casino games, while others specialise in online slots, and provide more different slots games than others. If you're a slots fan there are lots of casinos that offer as many as 100 different slots games, of all different varieties: classic 3 reel slots, video slots, multi line slots, and bonus feature slots.

Specialist slots casinos also tend to offer slots bonuses in one of two ways. Most of them will offer a special sign-up offer specifically for slots players. These offers can usually be claimed by signing up, making a first deposit and then making a specified amount of bets on one of the slots games - typically a multiple of the bonus amount. Once you have wagered the required amount, your bonus free money is automatically transferred into your casino account.

The other way of awarding slots bonuses is for the casino to offer prizes for playing certain slots games. One of the common ways of doing this is to award prizes for the most money wagered on a slot, or the most spins made in a given time period. The winners then have free money bonuses transferred into their accounts.

Online casinos that predominantly specialise in slots also often offer online slots tournaments. These run for a predetermined period of time, and usually offer prizes to the players that wager the most over the given time period. Some of them will offer free credits for players to play with, in return for a set entry fee. There are some great prizes on offer at these tournaments, ranging from overseas holidays to iPods.

Some online slots casinos also offer excellent VIP incentives to regular players. These most often take the form of loyalty points earned for all slots play, which can be redeemed for free cash in your casino account. Higher rollers obviously get higher rewards, including large cash bonuses. One casino even took a VIP slots player to Russia where he got to fly in a Mig fighter jet!

Online slots casinos also tend to offer better payout percentages than land-based casinos, which simply means that you have a better chance of winning more often. This alone is a great reason for playing slots online.
