You should always play online games with a good plan, set a limit amount for playing a day. Without setting some amount you may deposit all your amount and lose it all.
Gambling is risky, remember you earn your coins in a hard way so protect them. Gambling is profitable only if you will play in them a good way.
The thing is, this is easier said than done. because when you have the money to get back what you've lost from playing more, you always take the risk and wanted to took every chances you have to get it back. however, this is the most foolish thing you can do because the odd is so small compared to the chance of losing it all. If you want to stop, you should have done it before playing games. you should cut the expenses before playing.
