Free spins with deposit
Most online casinos offer free spins against a certain deposit level, as you can see at Casino Heroes Casino, for example, where there are regular free spin offers for each bankroll. Quite often, they are part of a new customer bonus pack that has had no deposit sign up games and now has more free spins per deposit as part of the Welcome Bonus offer.
It is also good to know here that in free spin packages such as the new customer bonus, the free spins are never credited all at once, but over a certain period of time. A good example of this is the Casumo online casino, where there are 180 free spins after the first deposit, which clear the account for free spins on 9 consecutive days.
Again, you should take a look at the bonus conditions, because there are often differences between the terms of the bonus sum and those of the free spins. Closer inspection is definitely advised, if you want to save yourself from surprises.
