A free spins plus match bonus offer will give you a helping of spins, but the online casino will also match your deposit up to a specified amount. For example, a typical offer might look like: 100% up to $200 plus 50 free spins.
In this example, if you deposited $20, the casino would give you $20 in bonus credits and activate a set of free spins. The spins might be given out all at once, or they might be delivered in batches every 24 hours.
This is best suited to players who want to make sizable deposits to take full advantage of the matched cash amount. The bonus terms on these offers tend to be more lenient than no deposit bonuses, so you should be able to extend your gameplay even further.
That said, be aware that you’ll usually have wagering requirements and other restrictions for both the free spins and the bonus cash, which can complicate things somewhat.
