Another important thing that is related to payout percentages is what is commonly called “gambler’s ruin”. What is that? With simple words it is a situation when a gambler has lost the last of his bank of gambling money and is no longer able to gamble. It sounds simple, but in fact it is more complicated, especially when one looks at the percentages calculations.
Every casino, web-based or land-based, hat its own little house advantage. What is the house advantage? It is the amount of money that the casino expects to keep from each played game on a long-term period. But, every player that plays constantly for a long period will stand a higher chance to reach the house edge.

        Below is an example that will explain this more clearly. Let's imagine a situation where the house advantage on a particular game is placed at 1%, and a player starts off with a bankroll of $100. In the event that the gambler never bets any of his accumulated winnings, theoretically he can expect to take home $99 of his original 100. On a speculative basis, should he continue to gamble and use his winnings, at this point -$99, he would lose 1% on average for the rest of the games he will play, and his winnings would go down to $98.01. This downfall 'will inevitably carry on until the player has no money left at all' - that is 'gambler's ruin'!
