Free games are the exact opposite of real money games, as players don't have to spend a cent to play. Besides the fun they generate, these games are meant to help players learn strategies, rules, and tricks of the games, with an aim of honing their gaming skills.
Once they get to grips with what the games entail, they can move a step further and play for real money. Sure, playing free casino games does not culminate in any cash winnings, but it helps the player to learn some important ropes, which helps them to approach real money games with confidence and even stand a chance to win.
In most cases, online casinos don't require players to sign up or download some software in order to play games for free. All the conditions have been simplified to encourage gamblers to play. However, signing up is is mandatory when it comes to playing for real money, as this involves money transactions.
It is important to note that not every casino game is available for free play. Each online casino tends to have its own selection of games that can be played in a free mode. Also, although most casino sites offer free games, some sites choose not to offer free games. Thus, the choice of casino could be a factor.
