There are definitely similarities to playing mobile casino and online casino. However, there is no denying that it's far easier to carry a smartphone or tablet with you.
Gambling online or on mobile should be a leisure activity, and it's always a good idea to set limits on your deposits, bet sizes and playing time. This is to protect your financial health, mental health and your relationships with other people that ultimately suffer when you gamble uncontrollably.
Follow some general rules like only playing with extra money set aside after you've met your expenses and walk away from losses.
