If you gamble, whether it be on a desktop or a mobile device there is a small percentage of players who could become addicted. Obviously, playing on a mobile device gives a player access wherever they are, but should always be classed as a leisure activity.
Whether you play casino games on a desktop or mobile device it's important to set spending limits, betting limits and time spent playing.

If you feel your gambling is getting out of control, reach out to a gambling charity such as begambleaware.org who can help with any gambling issues you may have..
