There is no fun in losing except some adrenaline that you may get from huge near misses during your play session. There is no fun at all when you are losing your balance for the simple reason that everyone when they start their gambling session they are not starting it to have fun but to win money and no one is really enjoying seeing their balance draining out. Sometimes during our gambling session we can hit a huge win which can make our brain a lot of dopamine and it may look like we are having fun for the moment but as soon as we lose our balance different emotions hit us, sadness and rage are what we feel at this stage. Thus I must say there is no real fun while you are losing your balance.
