Also as far as I know they have that loss limit feature although I'm not sure since I usually gamble manually and don't set anything as I gamble the amount which I can always afford to lose. Maybe they should explore this and see for their selves to know if they can set something that can remind them that they need to stop when their limit has been hit.
They have something similar. If you go to your account settings, you can scroll down until you find "Responsible Gambling." Click on that and you will see "Time Alert." You can set a time limit for your account starting at 15 mins and going up to 3 hours. After you have played for that amount of time, you will be notified and asked to stop. The other option they have is self-exclusion. I don't see deposit limits or loss limits, though.
