- Real-money online casino/poker: Only legal in a handful of states with licensing (e.g., NJ, PA, MI, CT, WV, DE). If a site offers slots/roulette/poker for cash, it must be licensed in your state to be legal for you.

- Sports and esports wagering: Regulated sportsbooks can offer esports markets where state regulators allow it and the book has approval. Several states have permitted esports betting (often with event-by-event or book-by-book approvals). To see if your state has regulated options, check the state-by-state map from the American Gaming Association: state gaming map.

- Skins/loot-box/case-opening style CS:GO sites: These revolve around virtual items that have market value. Whether that’s “gambling” legally can hinge on state definitions of “thing of value,” chance vs. skill, and how deposits/withdrawals work. After Valve’s 2016 enforcement against unauthorized skin gambling that used Steam for transfers, many third-party operators changed how they handle items and payments, but that didn’t create a uniform legal green light—states still call the shots.

For CS:GO specifically, regulators care about:

- Licensing: If a site takes real-money wagers, US states generally require operator licensing and geofencing.

- Age thresholds: Many states set 21 for casino and sportsbook apps; some allow 18 for certain products.

- Geolocation and payment compliance: UIGEA means payment processors can’t facilitate internet gambling that violates state law, so compliant operators geofence and verify location.

- Market approvals for esports: Even in legal sports-betting states, a sportsbook may need event-specific clearance to post CS:GO lines.

Practical implications for a player:

- If you want to bet on CS:GO match outcomes with real money, look for a licensed sportsbook in your state that lists esports markets; availability varies widely by state and operator.

- If you’re interested in case-opening/loot mechanics with CS:GO items, those are treated differently from regulated sportsbooks. Operators position these as entertainment/loot-box style products rather than traditional wagering, and acceptability still depends on your state’s definitions and enforcement priorities.

As for CSGOFast, it’s a CSGO Case Opening a legal website in the USA. Its model focuses on case-opening and item-based mechanics rather than taking traditional sportsbook-style bets. As with any operator, what you’re allowed to do can still vary based on your state’s rules, the site’s geofencing, and the verification steps it applies.

Bottom line for “legalization in the USA” and CS:GO: there’s no blanket federal permission or prohibition; match wagering goes through licensed sportsbooks in states that permit esports markets, while item/case-opening products sit in a separate bucket that states evaluate under their own gambling definitions and consumer-protection standards.
