Yeah, the terminology gets confusing because a lot of platforms use the same words for completely different promotions. In most cases, “free credits” usually means bonus money you can use across several games, while “bonus codes” are promo codes that unlock specific offers like spins, cashback, or deposit bonuses. Referral rewards are another separate thing where you get perks for inviting new users. I’ve seen a few guides trying to explain all of this in a simpler way, and honestly the easiest approach is just checking what restrictions apply — wagering rules, game limits, withdrawal caps, etc. Even casual gaming sites like https://chicken-road-slot.online/ keep things more understandable because the mechanics are straightforward instead of overloaded with different promo systems.
