While playing dice game, it's hard to stop whether you're in profit or losses because of our greediness and sometimes we can't control that but most of the time greediness will win. So I always play this dice game with small fixed amount and will not worry much about the end result. This way I can limit my loss for that particular session.
The problem with playing for fun is neglecting the strategy and budget cap of what you wanted to lose. Saying playing for fun without any suggestion of safety method and keeping oneself on check is the same way of saying, go on and get addicted to the fun, get yourself drown with happiness until you have depleted your money. At the end of the day it will be ok, just accept you have lost them all. Sound like irresponsible and bad advice to me. It would be better to just say, enjoy gambling but always keep check of yourself.
