The online slot tournaments which were once available at only a few casinos, have proved so popular that the big online gambling software company's have now all created their own versions.

Free slot tournaments are also referred to as freerolls, essentially meaning no purchase needed to enter.. At any given moment you can be participating in multiple freeroll slot tournaments.

Types of Free Slot Tournaments
Online slot tournaments have two formats under which they take place. One is called Sit and Go's and the other type is played is live.

Sit and Go's
These types of tournaments allow you to register for the tourney and play now or in the future. All that matters is that you partake before the tournament closes. Called sit and go's because you play when you want and then can return to see how your doing in the tournament, no need to stick around. Sit and go's are the most popular online.

Live Tournaments
Just the opposite of the Sit and Go's, live tournaments take place with all entrants spinning at the same time. With results immediately available after the countdown timer has expired. Live and in real time tournaments are available online, but their most popular at the land based casinos.

RTG tournaments are all of the Sit and Go variety , allowing you to register and check back later to see how you fared. All the RTG casinos have slot tournaments, but not all are equal. This inequality is caused by the number of players participating in them as RTG tournaments prize pools are based on the number of players entered.

The best destination to participate in an RTG slot tournament in our eyes is Intertops. The casino has set its eyes on catering to the tournament player and that has created a nice player base. In fact casino Titan has now begun having big prize pool events on a monthly basis in addition to their daily and weekly events. US accepted.
