Frequently Asked Questions (FAQ)
Frequently Asked Questions About the Download
Responsible Gaming — For Fun, Not Addiction
Aa 51 believes gaming should be a form of entertainment — not a habit or a source of financial harm. We encourage all users to set a personal budget and stick to it. The app includes deposit limits, session time reminders, and a self-exclusion feature. Gaming is strictly prohibited for anyone under 18, and we enforce an age verification process to ensure this. Keeping family members informed is also an important part of responsible gaming.
If you feel gaming is getting out of control, contact live support immediately or Responsible Gaming Page See. Reaching out to a family member or friend can be the most important step you take.
