Problem gambling can affect anyone. Warning signs include:
Spending more money or time gambling than you intended
Chasing losses — betting more to win back what you lost
Hiding gambling activities from family or friends
Borrowing money, selling possessions, or going into debt to gamble
Gambling interfering with work, school, or personal relationships
Feeling anxious, irritable, or depressed when not gambling
Failed attempts to cut back or stop gambling
Using gambling to escape stress, anxiety, or depression
Self-Exclusion
Every licensed US sportsbook is required to offer a self-exclusion program. If you want to stop gambling, you can self-exclude from individual sportsbooks or through your state's gaming commission.
DraftKings: Available through account settings or call 1-888-987-6828
FanDuel: Available through account settings or contact their responsible gambling team
BetMGM: Self-exclusion available through account settings
State programs: Many states offer statewide self-exclusion. Contact your state's gaming commission or visit NCPG's self-exclusion resource.
Responsible Gambling Guidelines
PromoGrind is designed for matched bettors and promo hunters who treat sportsbook promotions as a math exercise. To keep it that way:
Set a bankroll limit — only use money you can afford to lose entirely
Never chase losses — promo conversion is about guaranteed math, not chasing results
Take breaks — set time limits on your sessions
Keep records — use PromoGrind's P/L Ledger to track actual outcomes vs projected
Understand the math — this tool shows guaranteed conversion values; any variance beyond that is gambling, not promo hunting
Talk to someone — if gambling is causing problems, reach out to the helplines above
About PromoGrind
PromoGrind is a math calculator tool that helps users understand and calculate the conversion value of sportsbook promotional offers (bonus bets, deposit matches, profit boosts). It performs arithmetic on numbers you enter. It does not place bets, access sportsbook accounts, connect to the internet during calculations, or handle money of any kind.
This tool is analogous to a mortgage calculator or tax estimator. Using a calculator to understand a promotion is not gambling. Placing the actual bets is gambling, which is why responsible gambling practices still apply.
Age Restriction
PromoGrind is intended for users who are 21 years of age or older (18+ in states where permitted). Sportsbook accounts require age verification and are strictly 18+/21+. If you are under the legal gambling age in your jurisdiction, do not use sportsbook accounts or place bets.
Core calculators are available now with a free Vault membership. Live scanning, AI help, and other backend-dependent surfaces remain in beta until their services are activated.
