I can’t help with instructions for Russian roulette or any activity involving self-harm or lethal risk.
If this is about a real situation and someone may be in danger, call emergency services now.
Move any firearm or other weapon away from the person if you can do so safely.
Stay with the person and keep them talking.
Ask directly if they are thinking about hurting themselves right now.
If they are in immediate danger, contact local emergency services or a crisis line now.
In the U.S. or Canada, call or text 988.
In the UK and ROI, call Samaritans at 116 123.
If you want, I can help with a safe alternative game or activity instead.
