You may feel that it is not worth playing on free mobile bingo sites as you may feel that they will not have any prizes worth playing for or many good features. However, you may be surprised at how good some of them are. Obviously, without having to pay to play, you may not have any prize money or just very small amounts. This may not matter to some people though, as it depends on what they want to get form their bingo game. Obviously some people play because they want to win a huge amount of money and they enjoy the thrill they get form gambling for real money. However, there are other people that play because they just enjoy playing bingo and having a win, even without a monetary prize is fun for them. Think about which type of player you are so that you can decide whether it is worth playing on a free site.
You will also be wise to play a free site if you really enjoy bingo but cannot afford to pay out anything to play. You could still have the fun of the game without having to pay out any money. If you are new to online bingo it is also worth starting with a free site. You will be able to get used to playing online and thinking about what is expected from the sites. Get used to the controls and how to play as well as any chat functions. It is always wise to do this before you pay to play so that you get an idea of how to play first and do not waste your money while you get used to it. It is also good for anyone new to any sort of bingo as they can understand how the game works and decide whether they enjoy it before they pay anything to play.
It is probably wise to always try playing for free in the first instance. If the website or app that you choose has free and paid games, then play free ones first so that you can get used to the game first and see how it works and whether you enjoy it. If you decide that you like it but it would only be fun if you paid to play then at this stage you should pay for a game.
