Short answer: Responsible gaming is to keep the game as entertainment only, not spend more than you can afford to lose, and stop when it starts to cost you money, time, relationships or health.
bd99No results are guaranteed. The game is not a substitute for income, savings or investment. Never use borrowed money, daily expenses, rent, medical or emergency savings to play.
A simple measure of control is: set limits in advance, don't change decisions during the game, stop at set times whether winning or losing, and review your performance regularly.
