How casino sign-up bonuses actually work
A welcome bonus is a one-time offer for new players — you get it once, on your first deposit (sometimes just on registration). The deal usually looks like "200% up to $200 + 150 free spins", which means if you deposit $100, the casino adds another $200 on top, plus hands you 150 spins to use on selected slots.
The promo code is what tells the system which offer to apply. Without it, you might still get a generic bonus — but entering the right code at sign-up is usually how you unlock the enhanced version. Some casinos hide their best offers behind exclusive codes that don't appear anywhere on their site.
What to check before you claim
- Wagering requirement — how many times you need to play through the bonus before you can withdraw. 30x is reasonable, 50x+ is steep.
- Time limit — most bonuses expire in 7 to 30 days. Free spins often have a shorter window, sometimes just 24–72 hours.
- Minimum deposit — usually $10–$20 to activate a welcome offer. Check before you fund the account.
- Game restrictions — bonus funds often can't be used on live casino tables or certain slots. Free spins are almost always tied to one specific game.
- Max bet rule — while playing with a bonus, there's typically a cap (e.g. $5 per spin). Going over it can void the bonus entirely.
