All casinos offer free spins in some form. When you register with the likes of Bitstarz, Cryptowild, Betchain, Fortune Jack or Betcoin to mention but a few, you will be guaranteed of being rewarded with all three types of free spins that can be had.
Free Spin Rounds
Most slot games offer a free spin round where you will be awarded spins for getting 3 or more of a symbol, usually the Scatter symbol.
Free Spin Bonus
Once you make a deposit, the casino will offer you a set amount of free spins as a thank you. These usually range from 20 to 100 free spins but can vary from casino to casino.
No Deposit Free Spin Bonus
These are completely free spins where you are able to navigate around the Bitcoin casino and become familiar with its offerings without depositing your own money. These are typically offered alongside other bonuses and are a great introduction to the platform.
Besides the Welcome Bonus free spins, you will often find that casinos offer free spins periodically, e.g., For VIP guests, particular days of the week or to introduce a new slot.
