. The downfall of many online slots players is the downfall of many gamblers in general: Greed.  Many gamblers have told how they were up in profit after winning one or several big payoffs, but in their quest to win even more, ended up vanquishing their entire bankroll.  Whether chasing one's losses, or playing recklessly with one's bankroll, the usual suspect and deciding cause is a players greed.  This is why many players advise to quit when a slot win generates at least a 25% in bankroll revenue.  For some players this percentage is more.  All in all, a good stopping point is when the player has profited one hundred times their wager amount.  For $1 bets, this means a $100 win is a good time to wrap it up. (Even if this means breaking even) If winnings are not so much of an issue, the player may opt to continue gambling - And when half of the initial $100 profit is lost, may decide to quit.  Whatever the player is expecting to get out of the gambling session (as set forth in Tip #1) will decide what action the player should take. Just remember to be satisfied with a humble take, and to never - under any circumstances - chase after losses.
