Free spins are a great way in which you can play slots games without risking anything. You can score good and make nice levels of profits from these spins.
However, there are certain requirements placed on these free spins which make some providers better than others.
One of these parameters is the length of time in which you have to use the spins before they expire. The majority of casinos will give you 7 days to use them. Some will give you less.
ClubWorld Casino and Karamba provide free spins that never expire.
Many free spins allow you to instantly keep all of the profits generated, whereas others will require you to meet certain wagering requirements before you can withdraw these bonus funds.
BitStarz and Slots Magic have no wagering requirements while the majority of online casinos will require you to turn over the bonus funds at least 11 times. Slots Million only makes you do so 3 times.
The majority of casinos will credit the free spins to your account automatically, meaning that you do not need to enter any code or activate the bonus in some other fashion.
