Free spins usually look tempting, but in reality, they are mostly a waste of time. I haven't heard once in many years of anyone winning anything significant from them. The winnings are usually measly. Generally, casinos aren't going to give away real money for nothing. In most cases, free spins are just a way to keep players interested.
It's commun between all casinos to rewrd loyal active users with free bonuses or upon registration for newcomers. All casinos requires high wagering bonuses to eliminate possible abuses and to encourage users to deposit as well. What is different with 1win is the wide range of games to use the bonus, as with other casinos the bonus usually available to use only with selective games. Not impossible to win with free bonus but luck is in your side if you can complete the wagering requirement.
Free spins might be attractive, and in actual sense they do not make much profit. The size of most winnings is small and the withdrawal is not easy due to large wagering requirements. They are not being used by casinos to give away easy money but rather to attract and retain their players. Nonetheless, it does not mean that they cannot be helpful in experimenting with new games.
The ability to play more games using bonus is also a benefit with 1win when compared to most other sites. Nevertheless, one should not have too high expectations. One can be a winner but one must be lucky, play well and make sure one wagers well.
Nothing new with all this as we become used to the concept of the bonus as a part of marketing strategy rather than a real bonus to offer it as free money. But I would like to address the free bonus in 1win which is a little bit different because of the wide range of games available to use the bonus with. Usually using the bonus is limited to few games but 1win let the user chose between many choices which might give a great experience to try many games even if the bonus won't let him win a big money.
