No two online casino software brands are alike, though they may offer the same types of games, the quality and graphics can be totally different. Some online casino software companies offer two different ways to play. The most common way to play all of the games quickly is a version of the software that is compiled packed with all of the games, along with all of the information found on the site. Another method that is great for Mac users, or players who are using a public computer is the instant play version of the software.
