Usually, free spins are issued with a deposit or no deposit bonus and give the opportunity to make several free spins in such well-known slot machines as Starburst and many others.
You will not be able to withdraw the bonus immediately. To do this, you need to fulfill the wagering requirements, for example, wager the bonus 50 or 100 times. Pay attention to the payout percentage as well. If it is low, then your chances of a successful withdrawal may be close to zero. The only sure way to withdraw the bonus is to win a large amount in any slot and fulfill the wagering requirements. If you fail to win, the casino will set a limit on the maximum withdrawal of funds. The most common limit is € 100 or less. Frequently, free spins are also used for marketing purposes. Each spin can be wagered at the minimum bet (for example, 0.10 €). Of course, 35 free spins sounds better than the € 3.50 bonus, but in fact both bonuses have the same value.
Free spins are created and managed by game providers, so they are not available in the casino itself. You can get free spins only after starting a game, for example online slot Starburst . But there is one more nuance. Bonuses are credited to the game account only after the wagering conditions are met.
Free spins can really be profitable. But remember that they should by no means be the main criterion when choosing one or another online casino . The likelihood that real money will actually be credited to your account after meeting the conditions is very low.
