If the welcome offer for your country has free spins too, then you will get them after you've made the corresponding deposit. The free spins are usually credited on the next day, or in batches, depending on the offer.
You also might have to enter a Guts bonus code to avail yourself of this incentive and once you have done so you will receive a notification that the Guts free games are available.
Remember, that free spins need to be activated within 24 hours, and they are valid for 72 hours, after which they will be removed from your account. Guts also has regular special promotions where you can get free s pins.
The best thing about the Guts free spins is that all winnings are wager free and credited as cash!
