A new player welcome bonus is one that is made available only to those who have not registered and played with the casino before. They are generally rather large bonuses, usually 100% or more, and may at times include free spins as an extra bonus. They are designed to entice new players to register with the casino and make a deposit, the hope is, in doing so, those players will return often to the casino and deposit into their accounts or ultimately, become loyal members who play weekly.
