Welcome Offers
New players at Slot Boss can claim a free spins welcome offer, giving them a batch of wager-free spins on a specific slot game after making a qualifying deposit.
Conditions Explained
You must opt in to this offer during registration, not after. Once registered, you have 7 days to deposit and then a further 7 days to meet the wagering condition. The wagering requirement means you must bet your deposit once (1x) on eligible casino games before the free spins are released. Table games and live casino games don't count towards that requirement. The spins are tied to a single game, Big Bass Splash, and can't be used elsewhere. Once the spins arrive in your account, they expire after 3 days, so don't leave them sitting there. Winnings from the free spins are yours to keep and can be withdrawn without further wagering.
