The features of gambling that make it pleasurable (and hence potentially dangerous) are the way rewards are structured. Those features are:

• Occasional small rewards
• Unpredictable, irregular rewards
• An illusion of control (I.e the chance element may be disguised or the gambler rationalises that they have more control than they actually have)
• Losses disguised as wins (a payoff that helps hide the fact that overall the gambler is losing)
• The real chance of a large payoff

How many of those features match aspects of writing fiction for money?
