Yes and No. The rules on withdrawing money will be stipulated within the Terms and Conditions. More often than not, you will be asked to pay a wagering requirement. This being a multiple of the bonus money/winnings, that must be paid before you can withdraw the winnings.
If for example, you win ₹500 through your Free Spins and the wagering requirement is 35 X. You will have to deposit and wager ₹17,500 until that ₹500 can be recouped and withdrawn.
Find a Free Spins bonus without a wagering requirement and all the winnings are yours to instantly withdraw without any restrictions.
