I'm amazed to have discovered three to four clone websites with identical games and website layouts (sattaking would be one example). You always receive a bonus feature when you receive free spins on these websites. But you'll become much less fortunate after you make a deposit. Maybe the terms and conditions include that as well? The unknown. For what it's worth, the odds in the game won't likely change whether you play with free spins or actual money. Since the game engine is unaware of whether real money is being wagered or not, statistically speaking, reaching bonus rounds will be just as likely.
